Technical field
The present invention relates to the service end technical field, particularly a kind of Distributed Services end frame based on message queue of the Internet service architecture.
Background technology
In traditional service end, be all often by foreground client and memory interface customized.Therefore, the versatility of such service end, extensibility are all poor, and the cost compare of safeguarding is high.In case new demand and service occur, will spend many time go to safeguard and revise original code.
Now, the diversification of the quick change of demand and service is more and more general.Originally the single service end of tradition has been difficult to satisfy the demand of society.On the contrary, the service end of general high scalability loose coupling structure will become the main flow of service end technical field gradually.Solving the effective method of aforementioned technical problem is exactly a kind of general skeleton of design, cancels service end to the dependence of foreground client and memory interface, and it is therefrom spun off.
IoC(Inversion of Control), say intuitively, be exactly the relation between the container control program, and in non-traditional realization, directly controlled by program code.This is the concept place of so-called " controlling counter-rotating " namely.IoC also has another one name DI---and " rely on and inject (Dependency Injection) ".Relative IoC, " rely on and inject " described the design concept of IoC more exactly.The so-called dependence injected, and namely the dependence between assembly is determined in the runtime by container, figuratively speaking, namely dynamically certain dependence is injected among assembly by container.From in essence, IoC and DI change into present depending on " container " with the dependence of the relation between assembly and assembly by original dependence " target element ".
AOP (Aspect-Oriented Programming), towards tangent plane programming, the current programming technique that has become a kind of comparative maturity can be used for solving well the intersection focus problem that is distributed in modules in application system.In other words, can realize adding a kind of technology of function to the program dynamic unity in the situation that do not revise source code by precompile mode and runtime dynamic proxy exactly.Its mechanism comes from proxy mode, and it is related that purpose allows object and the relation between object (module and module) not come by code exactly, all by the management of configuration class declaration.
In the control counter-rotating with in the use of tangent plane programming technology, the Spring framework is undoubtedly most typical successful example, is used for management object.
Summary of the invention
One of technical problem that the present invention solves is for portability and the reusable degree of service end assembly low, and the problem of flexibility and extensibility deficiency provides a kind of loose coupling general Distributed Services end frame.Realization is carried out separating of dynamic binding, logic module and Common Services Components to client-requested with stores service, thereby greatly improves flexibility, transplantability and the extensibility of this framework.

Two the technical scheme that the present invention solves technical problem is: after the locating information of the dependence between solicit operation and method of servicing and parameter all is written to the configuration information of framework, service end is the message resolution module of the part of the Message Processing take request message as the parameter call framework just, returns to analysis result; The invocation of procedure part of service end take analysis result as the parameter call framework, corresponding method of servicing is called in reflection, returns and calls result; Service end is returned to response results to call result as the response package module of the Message Processing part of parameter call framework; Each part of framework can read configuration information automatically, thereby makes correct processing.
Three the technical scheme that the present invention solves technical problem is: the loose coupling interactive mode that adopts asynchronous message; When client need to be called service, to message center transmit operation message, the message subscribing client is obtained message from formation, the message subscribing client encapsulates this three steps by Interface realization message parse, the invocation of procedure and the response of calling this framework, at last the response of returning in framework is sent it back message center.
Four the technical scheme that the present invention solves technical problem is: request message is first resolved through the message resolution module of Message Processing part, give the invocation of procedure after resolving and partly call the respective service interface, to call again result and give the response package module of Message Processing part, result is packaged into request institute wants the form that obtains, return at last the response results after encapsulation; In addition, provide the dependence configuration information by dynamic dependency binding part to other two parts.
The present invention is based on the thinking of generic service end message call framework, service end is spun off pattern one to one from tradition, become the programming framework of the general loose coupling structure of a kind of light-type.The technology that this framework provides a kind of " Message Processing and the invocation of procedure " is carried out unified Message Processing and the invocation of procedure in a kind of general mode to dissimilar operation information.And can revise dynamically the dependence between request and service, make service end can respond rapidly different demand changes.Aspect framework, improved portability and the reusable degree of assembly, inject the machine-processed dependence that has alleviated between assembly because rely on; Aspect realizing, programming that can be more succinct realizes.Framework of the present invention not only can management object, can also be used to do message parse, carries out the work such as distributed process calls, and belongs to a distributed programming framework.The main feature of this framework of the present invention and method is: decoupling zero mainly contains the embodiment of two forms:
First embodiment is: between the various piece in framework, comprise between the core classes code of framework and between the framework platform at framework and place, form a kind of structure of loose coupling as far as possible, make framework that more flexibility be arranged, thereby replace certain layer and do not affect overall architecture if reach.
Second embodiment is: the decoupling zero of the upper layer application system at framework and its place.
Aspect the embodiment that realizes these two kinds of forms, the decoupling zero between the class of framework inside mainly realizes by the technology that control is reversed, and the decoupling zero of framework and upper layer application system realizes by the technology towards tangent plane.
The configuration of this framework by " dynamic dependency binding " this part defines tangent plane one by one, just belong to towards the enhancing of cutting into slices in programming as for " Message Processing " part, actual logic during he has defined tangent plane is such as the actual code of message parse and response encapsulation.In " invocation of procedure " part, carry out the tangent plane logic by the agency at last, wherein the agency refers to the agent object of practical business object.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1 is framework overall construction drawing of the present invention;
Fig. 2 is the exchange method block diagram between framework of the present invention and other application and service;
Fig. 3 is the data flow block diagram that framework internal request of the present invention is carried out.
Embodiment
As shown in Figure 1, represented the overall construction drawing of this framework, universal information is processed and invocation of procedure framework is made of dynamic dependency binding, Message Processing, these three parts of the invocation of procedure.Wherein the dynamic dependency binding comprises the configuration information class and relies on binding class; Message Processing comprises message parse and response encapsulation.In addition, message subscribing client of this framework and the common formation of other assemblies.
Following 3 basic principles of following when this framework carries out design and development:
1. directly do not create destination object in code, but describe the mode that creates them.
2. directly be not connected with the service object in code, need which service but describe which assembly with configuration data.
3. program when operation, is responsible for these object associations together by container.
The dynamic dependency binding:
Locating information, response locating information, these four elements of ISP that this part is injected operation requestor, parameter by dependence dynamically connect, and form a new integral body.Inject the machine-processed dependence that has alleviated between assembly because rely on, this is also that the J2EE platform is advocated the system development requirement of " Song Ouhe ".Can reduce widely like this requestor of object to the dependence of ISP's specific implementation logic, because concrete " locating information " that we will rely on separated from the requestor.Relevant example is described as follows shown in table:
Message Processing:
This part comprises message parse and two modules of the encapsulation of the response after the invocation of procedure before the invocation of procedure, designs according to the thought towards tangent plane programming, all belongs to the applied logic assembly that is separated.Their topmost effects are exactly to unify to carry out Message Processing according to the dependence that dynamic dependency binding part provides, thereby reduce duplicated code, build graceful solution.
The invocation of procedure:
Relating generally to of this part is proxy mode, singlet pattern and JAVA reflection calling technology.It is respectively general-purpose interface, agency, real object that proxy mode has three roles.What agency, real object were realized is same interface, with the attribute of real object as the agency, disclosed to client is the agency, when client call agency's method, the agency is in conjunction with the reflection calling technology of JAVA, call the real object method, provide relevant service after before calling.In order to guarantee only to exist in whole framework an agency's example as for the singlet pattern.
Use method of the present invention to be: after the locating information of the dependence between solicit operation and method of servicing and parameter all is written to the configuration information of framework, service end is the message resolution module of the part of the Message Processing take request message as the parameter call framework just, returns to analysis result.The invocation of procedure part of service end take analysis result as the parameter call framework, corresponding method of servicing is called in reflection, returns and calls result.Service end is returned to response results to call result as the response package module of the Message Processing part of parameter call framework.Each part of framework can read configuration information automatically, thereby makes correct processing, and Here it is controls counter-rotating and embodies towards the core of microtomy.
As shown in Figure 2, represent the interactive mode between this framework and other application and service, adopt the loose coupling interactive mode of asynchronous message.When client need to be called service, to message center transmit operation message, the message subscribing client is obtained message from formation, the message subscribing client just can realize that by the interface that calls this framework message parse, the invocation of procedure and response encapsulate this three steps, last only need to send it back message center to the response of returning in framework, the interacting activity between just having completed once request and having served.Operation as for framework inside is all that the dependence that automatically reads in configuration information is carried out.
As shown in Figure 3, represent the data flow that this framework internal request is carried out.Request message is first resolved through the message resolution module of Message Processing part, give the invocation of procedure after resolving and partly call the respective service interface, to call again result and give the response package module of Message Processing part, result is packaged into request institute wants the form that obtains, return at last the response results after encapsulation.In addition, dynamic dependency binding part provides the dependence configuration information to other two parts.
