Fig. 3 is the structural representation of the single application server in the embodiment of the invention.As shown in Figure 3, the main frame process is the background monitoring process that is deployed on every application server, is responsible for carrying out downloading-running and the deployment of application service.The main frame process can be set up long a connection with central server, accepts system commands such as deployment, renewal, monitoring by this length.The several application service may operate in the application process in an application server, and this application process also can be called the service shell.On the application server a plurality of application processes can be arranged.
In the present invention, based on application service platform system illustrated in figures 1 and 2, provide the application service development mode based on application component (AppBean).In the present invention, the exploitation of application service need be undertaken by the good several AppBean of expansion customization, a kind of AppBean is for the treatment of one type service request, and service request may be called from user client software, browser, internal reference or outside signaling.
In the exploitation moment of application service, AppBean can think an abstract base class, and all application services all can be derived from from this base class of AppBean.Below AppBean is introduced.
The abstraction interface of AppBean
-setup () realizes from installing
-prepare () realizes initializing resource
-run () realizes operation
Several subclasses of AppBean, each subclass may be handled multi-form signaling, and the application developer need select suitable subclass to go to realize the application of oneself, and wherein main subclass has following several:
-RemoteAppBean: each RemoteAppBean handles a specific Rpc request;
-HttpAppBean: handle a specific Http request;
-MessageAppBean: handle a specific message transaction;
Below above several AppBean are illustrated:
RemoteAppBean
Handle a specific Rpc request, may derive from following several scene
-derive from quoting of other AppBean;
-derive from proxy;
-derive from other system's external service;
Parameter interpretation
-﹤ A ﹥ required parameter, the strongly-typed definition;
-﹤ R ﹥ replys parameter, the strongly-typed definition;
The application service context AppContext of-﹤ C ﹥ particular type;
When calling an application service of deriving from from RemoteAppBean, must provide the application service context (AppContext) of the particular type that this application service states when realizing, for example:
The following statement of application service meeting of obtaining user profile:
1. from RemoteAppBean ﹤ GetOption, UserInfo derives among the UserContext ﹥;
A. required parameter ﹤ A ﹥ is GetOption, for obtaining some option parameter of user
B. replying parameter ﹤ R ﹥ is UserInfo, is the set of user profile
C. application service context ﹤ C ﹥ is UserContext, is the user profile of current context, and UserContext is used for identifying user ID
2. realize the process method logic of managing business
HttpAppBean
HttpAppBea is for the treatment of a specific Http request, and the Http request may come from:
-from the direct request of subscription client and browser, the request meeting is carried out the reverse proxy conversion by 7 layers of load of intelligence of HAP
-be directed to the request of other servers
Realize that a specific application service based on HttpAppBean need customize following parameter:
-application service context ﹤ C ﹥: the context of particular type;
-Context source: from where obtaining context ﹤ C ﹥;
-URL prefix: the URL prefix that this application service is handled.(the URL prefix is passed through
HttpPrefix metadata mark is handled, and back extended meeting is mentioned)
For example: develop one and be used for the flow process that the user unifies the application service of login authentication and be:
1. the base class from HttpAppBean derives from;
2. specifying application service context type ﹤ C ﹥ is SessionContext;
3. specify the Context source to be the ssic field among the cookie;
4. realize the process method, read HttpRequest, return HttpResponse after the processing and give client.
MessageAppBean
MessageAppBean is for the treatment of the message transaction of loose coupling, and a MessageAppBean handles the Message of a particular type, and MessageAppBean can monitor the message queue of this type, and begins to handle when message queue arrives;
Realize that a specific MessageAppBean need specify following parameter
-application service context ﹤ C ﹥: the context of particular type;
-type of message ﹤ A ﹥: specify strongly-typed Message;
-event title (Message Name): an overall unique name that is used for mark one class message;
MessageAppBean adopts the producer/consumer's pattern
-the producer can be pressed into message queue with the Message that produces
MessageQueueService.Enqueue(context,entity);
-can when starting, get back to registration in the message queue service as consumer's MessageAppBean, and subscribe to the Queue of particular type, begin to accept the content among the Queue;
-producers and consumers allows one-to-many, the mapping relations of multi-to-multi.
More than three kinds of AppBean have been carried out introducing for example.
By above-mentioned illustrating as can be seen, the parameter of each AppBean is all not quite alike, but all comprises this parameter of AppContext.
AppContext
In application service platform of the present invention system, application service context (AppContext) is the key of application call and resource location.Here application call comprises that acting server calls application service, and the application service of calling other in the application service, and these two kinds of application all need AppContext to realize the location of target application service.AppContext is divided into two parts from the data formation:
Uri: be string format, comprised user's index information, be responsible for the location, for example:
-id:230302023
-session:13910000001
Data: additional data
The strongly-typed data structure that-predefine is good;
-in some occasion, additional data can be offered the application service of back by Proxy.
The context that in system of the present invention, has some to pre-define:
-NullContext: predefined empty context, being used in does not need contextual occasion;
-SessionContext: predefined the context of preserving session id.
Except standard A ppContext, when using application service system platform of the present invention to carry out regarded as output controlling, need some relevant bases of first custom service, AppContext is exactly one of them.Exemplify one below about the specific embodiment of AppContext.
For example: use application service platform of the present invention system to open an instant message (IM) system, user in this IM system adopts an integer id to position, can customize the AppContex of this IM system so according to following mode, derive from called after UserContext from AppContext:
Uri part: " id:230302023 ", expression user's id, the id by this user so, application service position and database memory location that can consumer positioning;
The Data part:
-user's logging in network address;
-client type etc.;
As the UserContext that has customized the user, the AppBean that operates based on the user in all these systems can use UserContext as the ﹤ C ﹥ parameter of AppBean, as:
-obtain subscriber data;
-subscriber data is set;
-obtain buddy list etc.;
In addition, in application service platform of the present invention system, except the AppContext based on unique user is provided, type of service based on group also is provided, and exploitation also needs to customize the AppContext based on group based on the application service of group, the IM system uses an integer to be used for sign group, derive from from AppContext, called after GroupContext, the structure of GroupContext is as follows:
The Uri part: " group:123123 ", the sign id of group, expression user's id, by the id of this group, we can locate the application service position of group, with the database memory location so;
The Data part:
The session parameter of-group;
The mandate of-group etc.;
Behind the GroupContext that has customized based on group, all AppBean that operate based on group in this system can use GroupContext as the ﹤ C ﹥ parameter of AppBean, as:
-group name is set;
-renewal group authority;
-obtain group deferred information etc.
The apply metadata mark
In the present invention, an application service may comprise following metadata mark:
1.AppName(the name of application service and systematic name)
Name and the systematic name of statement AppBean;
-AppName(category="Core",name="AddBuddy")
Here xxx is that Java language is to the mark of program metadata.
The Category:name overall situation is unique;
Category can be used for the classification of AppBean;
-make things convenient for the O﹠M personnel to be configured and classify;
-in a Category, if allow the AppBean can be by other
AppBean visit among the Category must be with this AppBean statement
Become open or friendly;
Public (): allow all AppBean visits;
Friendlly (" Core "): only allow to specify the Category visit;
Friendlly (" Core:AddBuddy "): only allow to specify application access;
2.Stateful(the state information of application service)
Stateful("Presence")
An AppBean has state when statement, and then this AppBean can be kept at state in this machine internal memory;
The application that does not mark Stateful all is considered as stateless and uses, and this machine internal memory of banning use of carries out the preservation of state;
If the Stateful parameter the same (" Presence ") of a plurality of AppBean statements among Category, then these several AppBean start in the process, and do not allow separately heat to upgrade;
The heat that is applied in of Stateful can lost condition when upgrading, so go to replace with the memcache mode as far as possible, suggestion is only in the very high field startup of some performance requirement;
When certain AppBean is declared as Stateful, can adopt the mode of consistency Hash of the AppContext binding of this AppBean to carry out route at the visit of this AppBean;
3.BeforeHandler(the front service processing item)
Priority treatment front service before certain AppBean takes over control is judged daily record record, security audit etc. such as quota;
This Handler can interrupting service operation, revise professional suction parameter, can asynchronous process;
BeforeHandler(type=SecurityQuotaHandler.class,params=("AddBuddy“))；
Realize that a BeforeHandler need realize emoteAppBeanHandler＜A, R, C〉interface;
–void?run(RemoteAppHandlerTx<A,R,C>tx)；
4.AfterHandler(rearmounted Business Processing item)
Handle after can specifying in professional success, or carry out after the failure, or no matter successfully failure is all carried out;
AfterHandler(type=OperationLogHandler.class,result=OpResults.All,params=("AddBuddy“));
Handler can take complete required parameter, and is applied in the context data that adds among the context;
The result of Handler can not have influence on the return results of AppBean again
Implementation method is identical with BeforeHandler.
5.
The HttpPrefix(HTTP prefix is only at HttpAppBean)
Be used for the Http request scope that HttpAppBean of mark handles;
As: HttpPrefix ("/login.do ");
It is initial http request that this HttpAppBean of-expression handles with login.do.Message Name(event title is only at MessageAppBean)
The title that is used for a MessageAppBean of mark;
As: Message Name
6.ContextLoader(the load application Service context information)
Be used for AppBean of mark and how load AppContext
As: ContextLoader (name=" CookieParser ")
-expression removes to handle Context by the program of CookieParser by name;
-CookieParser program is built in the middle of the Proxy, removes to load user related information by the Cookie field of handling among the Http Request.
The application service development process based on AppBean has been introduced in the front.The minimum particle size of the exploitation of application service in the present invention is AppBean as can be seen.Next introduce application service that exploitation finishes how in the process of application service system platform deploy and operation.
The application server that the front is mentioned in the server cluster in the application service system platform can be divided into a plurality of groups, and an application service can be deployed on one group of application server, therefore at first introduces the packet configuration situation of the application server among the present invention.
In the present invention, the application server that can move application service need be tabulated and the server packet tabulation at the application server of the center service configuration overall situation specifically in the unified configuration of the overall situation.
The application server tabulation is as shown in table 1:
| Field name | The space segment type | Major key | Describe |
| ServerName | VarChar | Y | The application server title |
| ServerGroup | VarChar | ? | The server packet title |
| ServerAddress | VarChar | ? | Application server address |
Table 1
By table 1 as seen, the application server tabulation comprises following information: group names, application server address under application server title, the application server.
The server packet tabulation is as shown in table 2:
| Field name | Field type | Major key | Describe |
| GroupName | VarChar | Y | The server packet title |
| GroupDesc | VarChar | ? | The application server descriptor |
Table 2
By table 2 as seen, the server packet tabulation comprises: the application server descriptor in server packet title, the grouping.
Central server is deployed to this application service on the single application server according to external command when receiving the application service of uploading the outside, perhaps is deployed on a plurality of servers that belong to same group.
In actual applications, many application servers can be divided into different groups, be used for the different application service of operation, the benefit of server packet is as follows: 1. core application is specified application servers group specially, can guarantee that the resource of core application is used and stability; 2. specify independent application servers group to some newly-increased unsettled application, can reduce the risk of whole system; 3. be conducive to carry out the distribution of whole resource and the adjustment of network strategy.
Load application is served the process of application server
In the present invention, the application service meeting finished of exploitation is loaded on the application server in the server cluster and moves, and the route of acting server at this application service is customized on the application server of this application service of load.This process comprises the steps:
-developer compiles the code of the application service that exploitation is finished, and generates the deployment bag (jar bag) that is used for deployment;
-O﹠M personnel are by loading tool (being generally AppLoader), application type and the metadata of searching in the automatic analysis deployment bag by metadata mark, the data that analyze are write in the application service configuration information tabulation on the central server, and deployment wrapped pass on the central server.
Application service configuration information tabulation (hereinafter referred to as the Application table) is as shown in table 3:
Table 3
In table 3, can be by analyzing the metadata mark that Java application class and application class comprise about Annotations field: AppLoader, and extract type information and the metadata markup information of each AppBean, and the character string by JSON (JavaScript Object Notation) form is kept at the Annotations field of Application table, and concrete form is as follows:
The Annotations field comprises classInfo son field and classAnnotations son field;
Comprise current type, type of foundation, and the general shape parameter of type of foundation in the classInfo field;
The classAnnotations field comprises each metadata mark that this AppBean comprises, each parameter of metadata mark, by " key ", " value " mode is stored.
In table 3, except the bag title is disposed in the WorkerPackage(application service), the ServerGroup(application servers group) and Enabled(whether enable) field, the data of remaining field write in the application service configuration information tabulation in the central server automatically by loading tool.This has been avoided the trouble and the risk of errors that manually write.
The option whether-O﹠M personnel selection application service is disposed bag title, application servers group and enabled upgrades Application table table.
-central server is under O﹠M personnel's instruction, and each application server in the application servers group shown in the Application table sends the load instructions that loads the indicated application service deployment bag of Application table.
After the main frame process receives load instructions on the-application server, download the deployment bag of corresponding application service, and startup application process (AppWorker), this application process is moved this application service, and the running status of this application service is write in the application service operation information tabulation in the central server.
Application service operation information tabulation (hereinafter referred to as Running Worker table) is as shown in table 4:
Table 4
The application process of each startup all can connect with central server, and adds a running status record as shown in table 4 in the application service operation information tabulation of the overall situation.
In table 4, an application service path form can for:
rpc=tcp://192.168.1.100:8000;http=http://192.168.1.100:8080。
The routing policy of application service
Acting server (proxy) need call certain application service, when perhaps an application service need be called the Another application service, positions by the tabulation of application service configuration information and the tabulation of application service operation information just.
For example, in one embodiment of the invention, the flow process of address of searching a Http application service is as follows:
1. acting server receives the Http request that client or browser send;
2. acting server visit central server from the Annotations field (application service metadata mark field) of Application table, finds HttpPrefix(metadata markup information) record conforming to request URL during Http asks;
Specifically, enumerate the record in all Application table, find the HttpPrefix metadata mark among the Annotations, and whether the URL that judges request is initial with the value of HttpPrefix;
3. acting server generates AppContext according to the information of the Annotations field in the determined record in the step 2 (application service metadata mark field); Specifically, find the ContextLoader information of Annotations field, find the assignment function that meets the ContextLoader value, information extraction is as the input of function from the Cookie field of Http request message, the operation function obtains AppContext;
4. acting server is found out the record that AppWorkerName field (the application process title of operation) conforms to it according to the WorkerName field in the determined record in the step 2 (application process name section) from Running Worker table; Can there be many records to conform to it.
5. acting server disposes according to the Stateful in the Annotations field in the determined record in the step 2 and carries out following selection:
If a. be ' true ', then use the mode of consistency Hash from many RunningWorker, to select a record by AppContext information; Here, the consistency Hash is to calculate cryptographic Hash by the Uri character string of AppContext, selects the corresponding record of cryptographic Hash; Concrete hash algorithm can adopt the KETAMA algorithm;
If b. be ' false ', then select a RuningWorker record at random;
6. extract the address information in the ServiceURLs field (application service path field) in the selected RuningWorker record, according to realizing calling of application service to address information.
In the above example, acting server receives is request at HttpAppBean, therefore looks for the HttpPrefix of the correspondence in the Application table according to the URL in this request, to find the application service of correspondence.If what acting server received is the Rpc request corresponding with RemoteAppBean, far call service name (RemoteAppName) in then directly asking according to this Rpc is searched the consistent Application table with it of application service title (AppName) field, the table that this Application table generates when being the RemoteAppBean that disposes this Rpc request correspondence.If what acting server received is the Message message corresponding with MessageAppBean, then according to the event title in this message, the record that the Annotations field of showing from Application finds MessageName to conform to described event title, this record are the applied form data of application service of handling this message.
In the present invention, define and realize an application service with certain business function, this application service certainly will will visit various resources, provides application service as database, file server, memory object buffer server or other.In one embodiment of the invention, these resources are not the single-point services, just may there be the example of a plurality of vertical fractionations in the database of same type, in the present embodiment, an application service can accessed resources be bundled on the AppContext that states when realizing.
For example, we have stated an application service of obtaining user profile in front, and title GetUserInfoApp reads customer data base (UserDB) at the realization link of this application service, and the result is returned.Detailed process is as follows:
1. acting server receives the Http request that comes from client;
2. acting server is judged the application service that this request is corresponding by the URL of Http request; Be specially acting server by each the Application table on the orient core server, find the HttpPrefix Application table consistent with the URL of Http request in the Annotations field, the application service that this table is corresponding is this Http asks corresponding application service;
3. identifying the corresponding application service of this request according to the judgement acting server in the 2nd step is the request of GetUserInfoAPP, and needs UserContext as context parameters;
4. acting server is by the Application tabulation of the correspondence on the visit central server, according to the ContextLoader information creating UserContext of its Annotations field;
5. acting server adds the UserContext data of creating in the Http request from client, behind the path by inquiry Application tabulation and RunningWorker tabulation acquisition GetUserInfoAPP, the Http request is forwarded to the application server at GetUserInfoAPP place;
6. after the application process of the operation GetUserInfoAPP on the application server receives the Http request, extract UserContext, and give GetUserInfoAPP and handle;
7.GetUserInfoAPP read UserDB, when reading UserDB, carry out the location of UserDB by the id information among the UserContext;
8.GetUserInfoAPP organize returned packet, and return to acting server;
9. acting server returns to client with returned packet.
In the step 7 of said process, position by resource (Resource) table.Resource table in one embodiment of the invention is as shown in table 5:
Table 5
Can realize the different locate modes at different resource by realizing different mapping functions (Locator).For example in last example, the concrete configuration of resource table is as shown in table 6:
| Field name | Explanation of field | The example value |
| ResourceName | Resource name | UserDB |
| ResourceType | Resource type | Database |
| ContextType | The Context that the location relies on | UserContext |
| LocatorName | Location algorithm | ModDatabaseLocator |
| LocatorParams | The parameter of location algorithm | 5 |
Table 6
When then using id:1001 location UserDB in step 7, ModDatabaseLocator can take out 1001, and with 1001 except 5, getting remainder is 1, returns the database instance of UserDB.1 by name.
