Interface creating method and platform based on XML document description

Abstract

The invention provides an interface generating method and a platform based on the description of an XML document; the method comprises the following steps: an interface generating engine searches a composed interface request mapping file; a memory address of a description document of styles is obtained and the description document of styles is searched; a style document analytic module is called so as to generate a corresponding style model tree; the interface layout is set according to the attribute of root nodes of the style model tree and is traversed in a mode of depth-first; a reflection mechanism and a script mode are adopted to generate an executing code of the event of a sound monitor of an interface control corresponding to leaf nodes of the model tree, thus generating the interface control and forming the final interface; by adopting the style model cache interface style description document, the times of document reading of the interface generating engine are reduced and the executing efficiency of the interface generating engine is improved; the interface features in the specific application background are analyzed, and a module document which reflects the requirement of the common interface is composed in advance; by introducing the module document, the reusability of the existing work is improved and the workload of a secondary development period is reduced.

Description

technical field [0001] The invention belongs to the field of computer applications, and relates to an interface generation method and platform, in particular to an interface generation method and platform based on XML document description. Background technique [0002] With the continuous development of computer technology, interactive interface generation technology has attracted more and more attention. Reflection technology provides a method for programs to dynamically obtain and maintain class information and call methods of class objects in the runtime environment. The current mainstream programming languages ​​support reflection technology. For example, the java.lang.reflect package in the Java language encapsulates several APIs. Through these APIs, classes unknown to the program during compilation can be loaded and used at runtime. Because the reflection technology has the characteristic that it does not need to compile the target class in advance, it can be used to ...

Problems solved by technology

However, when different interfaces need to be created according to different interface requests, and there are a large number of interface requests, the use of hard coding will lead to low development efficiency, reduced software maintainability and scalability

In addition, the hard-coded interface generation method does not separate the business logic from the interface application logic. The result of mixing the two will lead to confusion in the development process and difficulty in understanding the program logic, mainly in the following two aspects:

[0005] (1) System development efficiency is not high

Due to the large number of interface requests, it is necessary to write its business logic and interface logic for each interface request. In addition, the interface controls of the interface requests show great similarity in appearance, layout or operation, resulting in a lot of simple repetition of coding sex labor

The tight coupling between business logic and interface logic makes system developers not only pay attention to the specific realization of business functions, but also consider the design and presentation of the interactive interface. They cannot concentrate all their energy on the realization of business logic, which affects system development. s efficiency

[0006] (2) System maintainability and scalability are not high

For each new interface request, a set of interface logic needs to be rewritten, the reusability of existing work is very low, and the system needs to be recompiled and deployed, and the secondary development efficiency is low

In addition, because the interface generation model and the business model are used together, when the business model changes, the interface model will also change accordingly, the workload is heavy and new errors are likely to occur; at the same time, with the increase in the complexity of the interface, The complexity of the interface model will also increase, and it will become very difficult to implement the interface model

The maintainability and scalability of the system are very low

[0007] In the case of a large number of interface requests, the currently proposed interface generation method is more complex in the development of customized interface, and the degree of code sharing is low. In particular, it cannot reduce the workload of secondary development, and reduces the maintainability and scalability of the system.
