Referring to Fig. 1, it is the flow chart of method that a kind of template that the embodiment of the present application provides renders；In the embodiment,
With WEB development modes, i.e., exemplified by MVC pattern, methods described includes：
Step 101：Obtain the web page browsing request of user；
Service platform receives the web page browsing request of user, and generally carries the system that user specifies in web page browsing request
One URLs (URL, Uniform Resource Locator, also known as web page address)：Service in the embodiment is put down
Platform, can be controller (Controller) in server or controller, such as MVC pattern etc..
Step 102：Determine template corresponding to the web page browsing request；
In the step, service platform can be asked according to web page browsing in carrying URL come template corresponding to determining, its
In, template, can be Velocity templates etc. by taking Java language as an example.
Step 103：The data for calling business service to return based on the template carry out template and rendered, webpage corresponding to generation
The page；
In the embodiment, it is as follows that a kind of template renders specific implementation process：Template is resolvable to abstract syntax tree, by time
Go through and render each node in abstract syntax tree to complete rendering for full page.During traversal, a node is often encountered,
With regard to being searched with the variable name of this node in template rendering context object (context), if it is found, just using variate-value
Go to render this node.This is the way of general template rendering engine, and the application is the base in the template rendering engine of routine
Certain extension is carried out on plinth, i.e., if not finding the variable name of the node in context, just with the variable name of the node
Business service corresponding to being searched from service Factory；If finding business service, the business service is carried out, and business will be performed
The returned data of service renders this node as variate-value.Finally, each node in the abstract syntax tree renders
Afterwards, Webpage is generated., wherein it is desired to illustrate, the Webpage in the present embodiment is html source codes.
The specific implementation process of the step refers to Fig. 2, will not be repeated here.
Step 104：The Webpage is returned to the user.
Also just say, the Webpage is returned to the user browser, in order to which the browser turns to Webpage
The user is shown to after changing.
In the embodiment, because the page obtained after rendering is html source codes, the html source codes only pass through browser
User can be shown to, therefore, it is necessary to which the html source codes first are returned into user browser, browser is shown by the page of conversion
Give the user.
In the embodiment of the present application, by the extension to rendering engine, the corresponding pass between template and business service is established
System, template renders can directly perform the data returned using business service, and it need not be that template enters industry to make Controller
The assembling for data of being engaged in, but allow the business service data of operation layer to be directly filled into the template of determination, so not only subtract significantly
Few Controller written in code, and improve the execution efficiency of template Rendering operations.
Also referring to Fig. 2, a kind of flow chart of the template render process provided for the embodiment of the present application, in the embodiment,
By service platform by taking controller as an example, specifically include：
Step 201：Read the template；
Step 202：The template of reading is resolved into abstract syntax tree；
Step 203：Each node in ergodic abstract syntax tree；
Step 204：Judge the node type of each node traversed, if variable, then perform step 205；Such as
Fruit is text data, performs step 210；
Step 205：Judge whether the variable name of the node is searched pair in template rendering context object (context)
The variate-value answered；If found, step 206 is performed；Otherwise, step 207 is performed；
Step 206：Go to render the node using the variate-value, render end afterwards；
Step 207：Judge corresponding business service whether is searched from service Factory using the variable name；If search
Arrive, perform step 208；Otherwise, step 209 is performed；
Step 208：Perform the business service, and using performing the data of the business service as variate-value to render
State node；
Step 209：Render exception；
Step 210；Go to render the node using the text data；
Step 211：After rendering each node in the abstract syntax tree, Webpage is generated.
That is, in the embodiment, template is resolvable to abstract syntax tree, is rendered by traversal in abstract syntax tree
Each node renders to complete full page.During traversal, a node is often encountered, just existed with the variable name of this node
Searched in template rendering context object (context), if it is found, just being gone to render this node with variate-value.This is one
As template rendering engine way, be to have carried out one on the basis of the template rendering engine of routine and in the embodiment of the present application
Fixed extension, i.e., if not finding the variable name in template rendering context object (context), variable name is just used from service
Business service corresponding to being searched in factory；If finding business service, the business service is carried out, the return number of business service
This node is rendered according to as variate-value.With velocity rendering engines, (for example a template of increasing income of Java language renders
Engine) exemplified by, the implementation that amended trigger-type template renders is as follows：
There is aforesaid way to understand that template can be parsed into abstract syntax tree by Velocity, and the abstract syntax tree includes：Become
Node is measured, such as, ASTReference etc., corresponding to variable node is used for representing that the node can be replaced by render process
Variate-value, for example the parameter variable of getVariableValue methods is exactly variable name.The embodiment of the present application is in parsing mould
During plate, the realization for replacing original Velocity is realized with this new variable node, to realize that velocity renders function
Enhancing and extension.
Optionally, in another embodiment, the embodiment can also include on the basis of examples detailed above：In template wash with watercolours
Before dye, the business service all using injection (Spring) container collection is relied on；Establish between the business service and Service name
Corresponding relation, in order to find corresponding business service according to the Service name.
Wherein, the business service all using injection (Spring) container collection is relied on, including：First hold in Spring
After device initialization, the method for all service objects in traversal Spring containers；Then, judge whether have in methods described specifically
Note mark (such as：Java language explains of this sort ServiceId (" XXX ")) note, if, it is determined that it is described
Method is exactly a method of servicing, and using the value of note as the key (key) in service Factory；Finally, by the method for servicing
A service result agent object is packaged as, the service structure agent object is saved in service Factory as value, so as to
Key (key) when template renders in service Factory searches service result agent object.
That is, in the embodiment, it is necessary to gather all business services in advance before template is rendered, when need
When wanting the implementing result of some service, it can be serviced according to corresponding to being found service name and perform service, obtain implementing result.
The interface for the service Factory that the embodiment of the present application provides is as follows：
In the embodiment, the realization of service Factory can be set according to business needs.The application is described below to carry
A kind of implementation process of the very typical service Factory supplied：
The collection of business service depends on Spring containers, after the initialization of Spring containers, travels through in Spring containers
The method of all service objects, if there is the specific note for explaining mark in method, then it is assumed that this method is exactly one
Method of servicing, then by the use of the value explained as the key in service Factory, method of servicing is packaged as a service result agency couple
As, be saved in by the use of this agent object as value in service Factory, key when being rendered in order to template in service Factory come
Search service result agent object.Wherein, it is specific explain mark (such as：Java language explains of this sort@ServiceId
(" XXX ")) usage it is as follows：
Wherein, it is specific explain mark (such as：Java language explains of this sort@ServiceId (" XXX ")) value phase
When then giving the method for service to take alias, it is consistent with the variable used in template.If with the mode of the application
To render template, then OfferService and SellerService and handle need not be called in Controller (controller)
Returning result is put into template rendering context object (context), directly calls above two to take when template renders automatically
The method of business.Template file content should be such：
<html>
<body>
A total of $ of commodity { offerListService.count } is individual
A total of $ of seller { serllerListService.size } is individual
</body>
</html>
It can be seen that variable name is directly corresponding with the title of the note in method in template.
The effect of service result agent object is to perform service according to current request, obtains final service result.Below
It is a kind of realization of typical service result agent object：
The design of the service result proxy class, service on the one hand is performed using current request (request) object, separately
On the one hand by the result cache of execution into request objects, in case next time calls same service result agent object again
Shi Chongfu calls service.When creating service result agent object, it is necessary to incoming IFaceMethodInvoker and
HttpServletRequest.IFaceMethodInvoker is exactly the packaging of the method serviced in fact,
HttpServletRequest is exactly current request, because the execution of method of servicing depends on current request object
(HttpServletRequest), such as：Different words are searched for, the number of commodity should be different, the business service behind this
Execution can be discussed in detail.
It should be noted that there are two attributes in CachedServiceResultProxy classes：
IFaceMethodInvoker serviceInvoker and HttpServletRequest request, during service execution, only need
The parameter information in request (request object), in the parameter for the method for being injected into service (similar SpirngMVC,
Wire Parameters function in Struts, Webx Open Framework, this is a kind of common technology), you can pass through java reflection modes
Method of servicing is performed, obtains service execution result.
It should be noted that a kind of present MVC (known web development modes) framework has a lot, popular has
Webx that SpringMVC, Struts2 and Ali commonly use etc..The method and apparatus that the template that the embodiment of the present application provides renders are not
