CN102012821A - Secondary development adaptation method - Google Patents

Abstract

The invention discloses a secondary development adaptation method, which comprises the following steps that: 1, a controller acquires original page data contents; 2, the controller establishes a document parsing interface and puts the interface into a script engine library simultaneously; 3, the controller calls a script engine to extract effective data, and in the process of calling the script engine, the engine automatically loads a corresponding script file for parsing, writing and executing work; and 4, the controller calls a template engine. By using the script engine and the template engine to extract data and generate a page, the adaptation method avoids a chaotic development mode and can greatly improve the development efficiency of secondary development personnel. Because the development of the data extraction and page generation is performed in different files, the development coupling is reduced, and the expansibility and maintainability of the system are improved.

Description

A kind of secondary development adaptation method

Technical field

The present invention relates to a kind of exploitation adaptation method, be specifically related to a kind of secondary development adaptation method.

Background technology

At present at the B/S system transplantation in the process of mobile phone mobile platform, need that secondary development is adaptive to be write on data extract and page layout code among the same XML.So just cause two kinds of different business logics of data extract and page layout to combine closely, cause code confusion in the adaptive process, extendability and maintainability have also fallen at the end simultaneously in the error rate height.

The page generates and need carry out from top to bottom, and this has just lost the maximum characteristics that data are applied in a flexible way.Can not carry out intercommunication with internal system, can't add other external informations.

Prior art has adopted DOM to add the principle that template instruction generates the page, but the technology that adopts data extract and page layout to combine closely can cause confusion, the error rate height, and can not carry out inter access to system.Simultaneously, data extract and page layout element are combined closely, and page layout has been lost dirigibility.DOM adds template instruction, and to generate the mode of the page higher to the cost of being familiar with development language.Data generate and page layout is finished in identical file, have lost extendability and maintainability fully.

Summary of the invention

In view of this, the object of the present invention is to provide a kind of secondary development adaptation method, data are extracted for script engine and template engine and the page generates, and has avoided chaotic development mode, can improve the development efficiency that secondary is opened personnel greatly.

The present invention is by the following technical solutions:

A kind of secondary development adaptation method comprises the steps:

Step 1 gets access to original page data content by controller;

Step 2, controller is created document and is resolved interface, simultaneously interface is put into the script engine storehouse;

Step 3, controller invoke script engine comes extracted valid data, and in the process of invoke script engine, engine loads automatically that the corresponding script file is resolved, compiling, execution work;

Step 4, controller calls template engine, and template engine obtains the template corresponding file by loading the template file storehouse, and template engine generates the new page by template file and corresponding data.

The invention has the beneficial effects as follows:

The present invention uses script engine and template engine is extracted by data and the page generates, and has avoided chaotic development mode, can improve the development efficiency that secondary is opened personnel greatly.

Script and template instruction have adopted Rhino and two frameworks of increasing income commonly used of Freemarker respectively, do not need important study just can develop, and have therefore reduced secondary development personnel's study threshold, have saved the cost of personnel training.

Because data extract is carried out in different files with the exploitation that the page generates, reduced the coupling of exploitation, improved the extendability and the maintainability of system.

Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can obtain instruction from the practice of the present invention to investigating hereinafter.Target of the present invention and other advantages can realize and obtain by specifically noted structure in following instructions or the accompanying drawing.

Description of drawings

Fig. 1 is a schematic diagram of the present invention.

Embodiment

Below in conjunction with drawings and Examples the present invention is further described:

As shown in Figure 1, the present invention includes script engine, template engine and document and resolve three modules of interface, script engine is to resolve interface by the script language calling document to extract data content.Script has adopted dynamic language storehouse Rhino to carry out script and has resolved.

Template engine has used template instruction Freemarker framework that the Page Template model is resolved.

Document is resolved interface and is converted original content of pages the label of standard to by HTMLParser, and is defined as good data extraction interface.

It can also be seen that by Fig. 1 the inventive method step is as follows:

Step 1 gets access to original page data content by controller;

Step 2, controller is created document and is resolved interface, simultaneously interface is put into the script engine storehouse;

Step 3, controller invoke script engine comes extracted valid data, and in the process of invoke script engine, engine loads automatically that the corresponding script file is resolved, compiling, execution work;

Step 4, controller calls template engine.Template engine obtains the template corresponding file by loading the template file storehouse, and template engine generates the new page by template file and corresponding data.

Claims (1)

1. a double-network communication method is characterized in that: comprise the steps:

Step 1 gets access to original page data content by controller;

Step 2, controller is created document and is resolved interface, simultaneously interface is put into the script engine storehouse;

Step 3, controller invoke script engine comes extracted valid data, and in the process of invoke script engine, engine loads automatically that the corresponding script file is resolved, compiling, execution work;

Step 4, controller calls template engine, and template engine obtains the template corresponding file by loading the template file storehouse, and template engine generates the new page by template file and corresponding data.
