Java code generating method

Abstract

The invention provides a Java code generating method. In the method, a template module, a data analyzing module, a code generating module and a data module are needed, and an automatic source code generating script is defined in the code generating module. A specific operating method comprises the following steps: extracting metadata, defining the metadata to form a metadata file, and storing in the data module; extracting the metadata file by using the data analyzing module, analyzing the metadata, acquiring the code template from the template module, and converting the metadata into a template object, wherein the code template is provided with a named parameter used for identifying the template object; and executing the automatic source code generating script by using the code generating module, assigning the named parameter in the code template by using the template object to generate a plurality of source code files, and storing the source code files at positions corresponding to the metadata file in the data module. The Java code generating method has the advantages of high maintainability, high code consistency, high reusability, higher development efficiency and lower manpower cost.

Description

technical field [0001] The invention specifically relates to a Java code generation method. Background technique [0002] Existing code generation methods are generally divided into two categories: passive code generation methods and active code generation methods. In the passive code generation method, a visual wizard is generally used to configure and generate part of the code, and then software developers make necessary edits and modifications to the code. This generation process is only performed once, and the modified code is not maintained; most of the current An Integrated Development Environment (IDE) or editor includes this method of code generation. However, the limitations of this code generation method are also obvious. The IDE or editor is only responsible for generating once, and the rest of the workload is the responsibility of the software developer. Regeneration will cover the modified code, and it is only applicable to some Scenarios, lack of configurabil...

Problems solved by technology

However, the existing active code generation method is directly performed through the database table, starting from the database table to parse, it must be converted into a table creation script corresponding to a certain database to create a database, which requires the code generation method to be adapted to a variety of mainstream database

In addition, although the code can be generated separately for a single newly added database table, all the generated codes are mixed and placed in packages at various levels, and cannot be generated according to the data correlation sub-package classification, and it is not easy to introduce custom identification in the database model stage , retrieval, exception and other logic
