Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
JSON data transfer device provided by the present application, can be applicable in the application environment such as Fig. 1, wherein client is
The computer terminal of JSON data, including but not limited to browser, cell phone application, PC host are sent, server, intelligence is eventually
End etc..Server-side is the computer equipment converted to JSON data or component, can be by server or server
Cluster composition.Destination client is the computer equipment or virtual terminal for having request of data to server-side, can be taken with cell phone application
Business device etc.；The JSON data after conversion are sent destination client by server-side.Between client and server-side, server-side and mesh
It marks by network connection between client, network can be cable network or wireless network.It is provided in an embodiment of the present invention
JSON data transfer device is applied to server-side.
In one embodiment, as shown in Fig. 2, providing a kind of JSON data transfer device, specific implementation flow includes
Following steps:
S1: the JSON data that client is sent are received, and JSON data instance is melted into JSON object.
In the present embodiment, JSON data can be stored in a manner of JSON file.JSON file is with ASCII
(American Standard Code for Information Interchange, ASCII) coding
Mode stores, and independent of operating system, quickly can be read or be generated by computer program, be a kind of common data exchange
Format.
Wherein, ASCII is a set of computer code's system based on the Latin alphabet, is mainly used for showing current english and other
Western-European languages are single byte coded systems most general now.
JSON data are made of key-value pair (key-value), and key-value pair includes a key name and corresponding with the key name
Key assignments.One JSON data includes at least one key-value pair；It is separated between key name and key assignments by colon；Each key-value pair with
Comma terminates；Key name need to add quotation marks；Add quotation marks if key assignments is character type data, quotation marks are not added in non-character type data；One
There can be sub- JSON data in JSON data, each data in sub- JSON data using left bracket as starting, make by right bracket
To terminate.JSON file starts using opening brace as file, right braces is as the end of file, and sub- JSON data are included greatly with a left side
End as sub- JSON data of beginning, right braces number as sub- JSON data.
For example, a JSON file about student information can be expressed as follows:
Instantiation refers in the programming of object-oriented, creates the process of object.Object is data in Object-Oriented Programming
The basic unit of storage and processing, object include attribute-name and method.
JSON data instance is melted into JSON object by server-side, i.e. server-side creates new object, using JSON data as
The data flow of input carries out the process of assignment to newly-built object；After JSON object is newly-built to server-side and instantiation
The common name of object.
Server-side instantiates the JSON data of the JSON document form received, is converted into JSON object.
Specifically, JSON data being carried out unserializing can also be can be used by calling inside Java from tape function
Ready-made third party's tool, such as JSON-LIB, the FastJson of Ali company, the Gson of Google, the Jackson of open source
Deng.
Still by step S1 about the JSON file of student information for, by calling inside Java from tape function or third
Side's parsing JSON tool, the JSON object after instantiation are student's object, in the attribute and JSON file which includes
Key name corresponds, including " student name ", " age ", " class "；The object further includes a subobject " interim achievement ", son
The attribute of object includes " Chinese language " and " mathematics ".Key assignments corresponds in student's object's property value and JSON file.
S2: using reflection mechanism, obtains the attribute-name of JSON object, and corresponding with each attribute-name in the JSON object
Attribute value.
Reflection (Reflection) mechanism refers to accessible program, detection and modification itself state or one kind of behavior
Ability.Language based on reflection mechanism includes Python, OpenC++, MetaXa, Java etc..By taking Java reflection mechanism as an example,
In operating status, for any one class, it can determine the whole attributes and method of this class by Java reflection mechanism；For
Any one object can call its any one method and attribute, it might even be possible to modify the privately owned of an object
The value of private attribute.It, can be in the type of test object at runtime based on reflection mechanism；Pair of some class of dynamic construction
As；Detect the attribute and method of class；Any method for calling object；Modify the visibility of constructed fuction, method, attribute.
Server-side is by reflection mechanism, the attribute-name of available JSON object, and with each category in the JSON object
The property corresponding attribute value of name.
Specifically, server-side is by the forName () method for the Class class for calling Java included, with pair of JSON object
It is inputted as name is used as, the example for obtaining JSON object；GetFields () method is called to obtain with the example of obtained JSON object
Take attribute-name in JSON object；Continue to call get () method to obtain in the JSON object often with the example of obtained JSON object
The corresponding attribute value of a attribute-name.
For example, server-side can obtain its all properties name and category by reflection mechanism if JSON object is student information
Property value.
S3: the preset common java class set of traversal, and obtained in preset common java class set using reflection mechanism
The attribute-name of each common java class.
Common Java object is referred to as POJO (Plain Ordinary Java Object/Pure Old Java
Object).POJO is for special Java object, and POJO is used to emphasize that it is a common Java object, without
It is a special object.Special object, which is mainly used to refer to those, defers to specific Java object model, agreement or frame
The Java object of (such as EJB), and POJO is one other than Java language specification, unrestricted Java object.
Common Java object is the example of common java class, and the set of common java class is to be needed to carry out according to pre-set business
The set of the class of division.For example, if server-side needs the operation that accesses to three databases or tables of data, each database or
Tables of data needs different data as input, then usual server-side define three different POJO respectively to three databases or
Tables of data accesses operation, and therefore, server-side needs in the process of running, and preset three different common java class are real
Example turns to three POJO.
Still by taking the student information in step S1 as an example, server-side needs the operation that accesses to three tables of data, three numbers
It is Basic Information Table, preference blank, summary respectively according to table.Wherein, the field that Basic Information Table includes has student's
Name, age, class etc., the field for including in preference blank have the hobby etc. of student, include in summary
Field has the title etc. of the every subject of student.Three classes can be preset by system or developer, be essential information class respectively, emerging
Interest hobby class, achievement class；The attribute-name of three classes is corresponded with the field in three tables of data.Server-side uses reflection machine
System, obtains the attribute-name of each general category.
Specifically, common java class set can be defined in the form of static array, each element generation in array
The class name of one, table common java class.Server-side is by traversal array, using the class name of each common java class as input, and
The getDeclaredFields () method of calling is to obtain attribute all in such, until having traversed member all in array
Element.To obtain the attribute-name of all common java class.
S4: for each common java class in preset common java class set, by the attribute-name of common java class with
The attribute-name of JSON object is compared one by one, if all properties name of common java class is included in the attribute-name of JSON object
In, then the common java class is instantiated as common Java object, and by category identical with the common java class in JSON object
The property corresponding attribute value of name is assigned to common Java object.
Server-side needs to instantiate them after the attribute-name for obtaining each common java class, i.e., to each common
The attribute of java class carries out assignment.
Specifically, a preset common java class is taken, its all properties name is traversed, by the attribute of each common java class
Name is compared with the attribute-name in JSON object, if the attribute-name of common java class and some attribute famous prime minister in JSON object
Together, then server-side calls new () method, creates common Java object, and by attribute corresponding with the attribute-name in JSON object
Value is assigned to newly created common Java object.And so on, it is common until all common java class whole examples to be melted into
Until Java object.
In the present embodiment, the JSON data that client is sent are received, and the JSON data instance is melted into JSON pairs
As；Using reflection mechanism, the attribute-name and attribute value of JSON object are obtained in real time；Preset common java class set is carried out
Traversal obtains the attribute-name of each common java class in preset common java class set using reflection mechanism, then by JSON
The attribute-name of object is compared with the attribute-name of each common java class, if the attribute-name of JSON object and common java class
Attribute-name is equal, then the common java class is instantiated as common Java object, and will be corresponding to the attribute-name of the JSON object
Attribute value be assigned to the common Java object, JSON data are split to realize, and be mapped to multiple common Java
On object.Due to using reflection mechanism, the conversion process of entire JSON data is real-time dynamicly；According to the need of practical application
It wants, the JSON data fractionation that structure is complicated, data volume is big is converted into common Java object, system memory resource is saved and opens
Pin, improves system response time.
Further, in one embodiment, as shown in figure 3, after step s4, that is, being directed to preset common java class collection
Each common java class in conjunction, compared with the attribute-name of common java class is carried out one by one with the attribute-name of JSON object, if commonly
The all properties name of java class is included in the attribute-name of JSON object, then the common java class is instantiated as common Java pairs
As, and by the corresponding attribute value of attribute-name identical with the common java class in JSON object be assigned to common Java object it
Afterwards, JSON data transfer device further includes following steps:
S5: if receiving the data acquisition request of destination client, common Java object is converted into data transmission pair
As.
Data connection object is referred to as DTO (Data Transfer Object), is between not homologous ray or system
Different software layer between the data medium that carries out data transmission or exchange.
Destination client is the computer equipment or virtual terminal for having request of data to server-side.Usually for safety
Consider, server-side only passes information related with the request of data that destination client proposes, to guarantee other information
Safety.
For example, a tables of data of server-side has 50 fields, then corresponding common Java object has 50 attributes.But
It only needs to show 10 fields on the interface of destination client, then when destination client proposes data acquisition request, must not
Entire common Java object is transmitted to destination client, therefore, server-side is extracted from common Java object and obtained with data
Relevant 10 attributes of request are taken, and are converted into data connection object.
Specifically, the data acquisition request that destination client is sent can submit data acquisition request, number by Web page
According to the class name in acquisition request including data transmission class.Server-side uses reflection mechanism, using the class name of data transmission class as defeated
Enter parameter, obtains the attribute-name of data transmission class；Then by the attribute-name of the attribute-name of common Java object and data transmission class
It is compared, if the attribute-name of common Java object is identical as the data transmission attribute-name of class, calls new () method newly-built
Data connection object, and attribute value corresponding with the attribute-name of the common Java object is assigned to data connection object, thus
Complete the instantiation of data connection object.
S6: target data corresponding with data acquisition request in common Java object is sent to using data connection object
Destination client.
Data connection object after instantiating in step S5, it is corresponding to contain destination client data acquisition request
Target data.Data connection object can be sent to destination client by Web page or socket by server-side.
In the present embodiment, server-side uses reflection mechanism, by number relevant to the data acquisition request of destination client
According to, extracted from common Java object, generate data connection object simultaneously return to destination client.Due to common Java pairs
The attribute-name of elephant and the field name of tables of data are correspondingly, to be carried out data transmission by data connection object, will not be exposed
The data structure of entire tables of data, is conducive to data safety.
Further, as shown in figure 4, in one embodiment, for step S1, that is, receiving the JSON number that client is sent
According to, and JSON data instance is melted into JSON object, specifically comprise the following steps:
S11: the JSON data that client is sent are received.
Server-side can receive JSON data by Web page.In Web page preset service end need received data and
The data type of the data.It is such as defined in the list of Web page field " student name ", " age " and " class ", and
Corresponding data type is character type, integer and character type etc..
In addition, a marker bit can also be preset in Web page, this time sent belonging to JSON data for representing client
Request type.By insuring, for surrender and continuation of insurance for insurance, have in Web page insure, item is chosen in surrender or continuation of insurance, use
Family is chosen when submitting JSON data by client, so that the backstage Web is able to know which the JSON of the secondary submission belongs to
Request type.
Specifically, the JSON data received can be stored as JSON file by server-side.
S12: according to the request type of JSON data, interception corresponding with request type is read from preset configuration file
Path.
A global configuration table can be preset except server-side local or server-side, which can be
Simple text formatting is closed for recording the JSON data that server-side receives with class name, request type, the corresponding of interception path
System.Wherein, intercepting path is a file directory name in server-side.The corresponding class name of every JSON data, it is corresponding a kind of
Request type, a corresponding interception path.
For example, the received JSON data of server-side are about policy information, about supplier information, about member
Work information etc..Be declaration form object about the corresponding object naming of policy information, corresponding interceptions path is " baodan "；
Be supply quotient object about the corresponding object naming of supplier information, corresponding interceptions path is " gongyingshang "；With
It is employee's object about the corresponding object naming of employee information, corresponding interception path is " yuangong ".
Intercepting path can configure in file SpringMVC.xml.File SpringMVC.xml is under Spring frame
A configuration file.Spring is the design level frame an of open source code, is the Java exploitation frame an of lightweight
Frame, what he solved is the loose coupling problem of Business Logic He other each layers.For large-scale Web application system, usually first will
Spring is deployed on server, and then further according to the needs of practical application, secondary development is done on Spring.It does so sufficiently
The existing interface of Spring frame is utilized, avoids the development of simple repeatability, and can quickly develop and be suitble to itself industry
The application that business needs.
Specifically, the marker bit in JSON data that server-side detection receives, then according to marker bit in global configuration
Interception path corresponding to the JSON data is inquired in table.For example, search is mvc:mapping in SpringMVC.xml
Value after path field:
<mvc:mapping path="/shouxian/* "/>
Wherein, " mvc:mapping path " is represented in Spring configuration file for defining the label of filtration path；
" baodan " represents the catalogue of declaration form；"/shouxian/* " represents the All Files under baodan catalogue, be configured so that so that
The request event that All Files trigger under baodan catalogue, can be intercepted.
S13: JSON data distribution is given and intercepts the corresponding blocker in path, by JSON data instance in blocker
At JSON object.
Blocker is the corresponding executing subject for intercepting JSON data under path of processing.
Specifically, server-side can search for the value after bean class field in SpringMVC.xml:
<bean class="com.base.baodan"></bean>
Wherein, " bean class " represents the label of the class of blocker；" com.base.baodan " is for interception path
The class name of the blocker of "/baodan/* ".Such method be used under declaration form catalogue All Files trigger request event into
Row intercept process.It is to be appreciated that different interception paths corresponds to different blockers, and different business demands is corresponding different
Interception path, server-side can be handled JSON data distribution to different blocker, to realize the classification to JSON data
And shunting.
In the present embodiment, server-side can classify to the JSON data received according to the request type belonging to it
And shunting, it is handled with the blocker for being given to different, allows to customize more JSON data transformation interfaces, improve simultaneously
Treatment effeciency.
Further, as shown in figure 5, in one embodiment, for step S4, that is, being directed to preset common java class set
In each common java class, compared with the attribute-name of the attribute-name of common java class and JSON object is carried out one by one, if commonly
The all properties name of java class is included in the attribute-name of JSON object, then the common java class is instantiated as common Java pairs
As, and the corresponding attribute value of attribute-name identical with the common java class in JSON object is assigned to common Java object, have
Body may include following specific steps:
S41: it is added to the attribute-name of JSON object as array element in the first array.
Specifically, server-side creates an interim array, as the first array, and the JSON that will be obtained by reflection mechanism
The attribute-name of object is all added in first array.
S42: the attribute-name of common java class each in preset common java class set is added to as array element
In second array, and delete the attribute-name of duplicate common java class in the second array.
Due to the common java class in preset common java class set be according to different business need it is preset, data it
Between the possibility that overlaps, therefore, it is necessary to delete wherein duplicate attribute-name.For example, three relevant to policy information general
Logical java class, is respectively used to different business processings, then the shared attribute-name in three common java class may have declaration form odd numbers,
Insurer's name etc..
Specifically, server-side creates an interim array, as the second array, and will obtain by reflection mechanism common
The attribute-name of java class is all added in second array, and deletes duplicate attribute-name in the second array.
S43: the first array is compared with the second array, if the element of the element number of the first array and the second array
Number is equal, and the element value of the first array is equal with the element value of the second array, then is instantiated as common java class general
Logical Java object, and the corresponding attribute value of attribute-name identical with the common java class in JSON object is assigned to common Java
Object.
Specifically, server-side can call list.size () method to obtain the length and the second array of the first array respectively
Length, to judge whether the element number of two arrays equal；If element number is equal, server-side can call equals
Whether () method compares each element value in array equal；If each element value is equal, common java class is instantiated as
