Automatic generation realizing method and device for entity classes

Abstract

The invention discloses an automatic generation realizing method and an automatic generation realizing device for entity classes. The method comprises the steps of deploying a configuration document including field data information of a plurality of entity classes; reading and parsing the configuration document when an information system is started, and storing the name information of the parsed entity classes and the corresponding field data information into an entity information management interface; acquiring a user input, and transmitting the names of the corresponding target entity classes to an entity information management interface; acquiring the field data information of the target entity classes according to the names of the target entity classes by the entity information management interface, compiling class codes after the class codes are generated by at least one entity class rule, acquiring non-parameter constructors of the entities after the compiling, and executing the non-parameter constructors to generate and return a target entity object. By adopting the invention, a developer does not need to generate the entity classes by manual compiling or a third party tool, therefore the working efficiency of the developer can be improved.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a method and device for realizing the automatic generation of entity classes. Background technique [0002] At present, in the process of information system development, it will involve the processing of a large amount of data and information, and most of the data and information need to be written by developers into entity classes, so that the system can use entity classes in different The attributes and relationships of these entity classes are needed for a long time, sometimes even in the entire life of the information system. Therefore, the entity class is particularly important for the development of the information system. [0003] The so-called entity class refers to the class used to model the information and related behaviors that must be stored. Its main responsibility is to store and manage data and information inside the information system. Enti...

Problems solved by technology

[0004] 1. The entity class must be a public class, and its access attribute must be set to public;

[0005] 2. The entity class must have a parameterless public constructor;

In the existing technology, these entity classes are manually written by developers, and the workload faced by developers is often very huge, which causes a large increase in labor costs to a certain extent, and its work efficiency is also low

In some applications, changes in requirements and business may also be involved. However, these changes in requirements and business will also involve the modification of entity classes, so that at this time developers need to manually modify entity classes. In addition, all associated The business code of the modified entity class must also be modified synchronously, which undoubtedly further increases the development workload of developers

In addition, if the modification of the entity class occurs after the information system has been launched, it will have to face the problem of disconnecting the information system for system upgrade. This will affect the continuity of the user's business and reduce the user experience
