Method and device for generating codes

Abstract

The invention provides a method and device for generating codes. The method comprises the steps that service object models are created for all services of the Web application, wherein creation of the service object models comprises creation of service entities of the services and creation of associated relations of all service entities; an interface model is created for the Web application, wherein the interface model comprises interface templates corresponding to the service entities in the service object models; the codes are generated by a code generation engine according to the service object models and the interface model. Due to the fact that the service object models of all services of the application are created, the interface model of the application is created, and then the codes are generated by the code generation engine according to the service object models and the interface model, developers can obtain needed program codes through the code generation engine after creating the service object models and determining display forms of all services in the interface of application software, a large amount of programming work of the developers is omitted, and further application development efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the field of programming, and more specifically, relates to a code generation method and device. Background technique [0002] In the prior art, the concept of layering is generally applied in the development of Web applications to increase the scalability and reusability of the application system; a typical layering method is to divide Web applications into presentation layer, business logic layer and persistence layer There are three levels in total. Among them, the presentation layer is the definition of some common Web components, including forms, lists, trees, buttons, etc.; the business logic layer is for adding, deleting, modifying, and checking operations for different business objects; the persistence layer is for different persistent objects. Data access operations, including insert, query, modify, and delete. [0003] For each of the above three layers, the corresponding open source framework can be used to...
