Relational database based generation method of J2EE code

Abstract

The invention discloses a relational database based generation method of J2EE codes, comprising the following steps: 1. object code template definition setting: defining an invariable code as a template and a variable code as a macro according to an existing frame; 2. external data acquisition: acquiring a relational database list structure parameter, database object annotation information, a structuralized query command, a code generation configuration parameter and an operating system parameter; 3. logic operation: obtaining the macro related to an object code through logic operation according to the acquired parameters; and 4. code generation: applying the macro to the code template to generate the object code of an MVC three-layer frame. The invention realizes an integral technical proposal to generate the J2EE codes on the basis of the relational database, guided by a two to eight principle of J2EE software development and according to a two to eight principle of the Barrett law that 80 percent of a total result is formed by 20 percent of total consumed time.

Description

technical field [0001] The invention relates to a method for generating J2EE codes, in particular to a method for generating J2EE codes based on a relational database. Background technique [0002] In addition to the early implementation of informatization in finance and telecommunications, the pace of informatization in various industries such as e-government, e-commerce, and enterprise informatization is also accelerating. The most prominent among them is that a large number of information management projects developed according to the J2EE (JAVA 2 Enterprise Edition) standard emerged as the times require. Such projects often appear in a certain period of time and the development time is urgent. Most of them are WEB application systems based on the B / S structure of the relational database system; the purpose of this application system is to solve business problems in a certain field. Configuration is also a real problem. In the process of software development and mainten...

Problems solved by technology

In the process of software development and maintenance, there are a large number of basic data object maintenance in any information system, most of which are simple maintenance functions, and the business logic is not complicated. However, due to the large number of basic data objects, even if the same and similar modules are copied, Pasting also requires a lot of work to complete; program debugging and program code maintenance are cumbersome, how to help developers free themselves from cumbersome coding technical details, reduce the workload of repetitive code development, and make them focus on Focusing on business issues and logic processing, and improving development efficiency and quality are the subjects that technicians in the field have been studying
