Description

Rapid development platform based on separation of front end and rear end of engine mode and use method thereof
Technical Field
The invention relates to the technical field of software development, in particular to a rapid development platform based on separation of a front end and a rear end of an engine mode and a using method thereof.
Background
Informatization is a continuously evolving process, accompanied by the construction of a large number of information system projects. In these information systems, there are many businesses with similar processes. These similar businesses are repeatedly developed by front-end and back-end developers, and in the case of very urgent project delivery time, the developers are required to overtime or invest more personnel, and a lot of manpower, material resources and financial resources are consumed. The basic functions of the information background management system of the current enterprise level and government projects are similar, the displayed content and form are relatively fixed, the customized service module occupies a small percentage of the whole background project, and the reusability of the service function is relatively low. Under the condition of fully considering the current situation, if the project of the whole background system can be commercialized with the aim of 'development', the project development time can be greatly reduced, and most basic general functions of various projects can be realized through configuration. Meanwhile, independent modular development can also meet the customization service of the project, and the work is finished more efficiently. After development platforms are generated, although a large amount of programming time of programmers is reduced, the effects of many development platforms are not ideal, for example, some development platforms are complex and difficult to master; some development platforms have poor universality; some codes need to be generated, and no perception updating can be realized; still further, many codes still need to be written, and so on.
The existing technical scheme provides a visual development mode, and a platform comprises a JSP configuration module, a JAVA configuration module, a process configuration module and a menu configuration module. The method realizes the rapid configuration of a front-end display interface, a back-end service processing logic and a service processing flow, not only supports common page elements, components and common service processing methods, but also keeps sufficient expandability, provides the introduction of self-defined js, css and java methods, and greatly enhances the flexibility and the applicability. JSP + Java technology is adopted for development, codes are generated through the code generator, research and development personnel do not need to write the codes, and development efficiency is improved. However, the above solution has the following disadvantages: the style of the front-end interface is old, the adopted technology is outdated, the interface layout is fixed, the configuration is not flexible enough, the mode of generating codes is adopted to realize rapid development, although the customized service is more convenient, the codes are regenerated when the configuration is modified, the project needs to be redeployed to take effect, and the method is not simple and convenient and cannot be rapidly delivered. And a front-end and rear-end separation framework is not adopted, the coupling is too high, the code maintenance cost is high, and the concurrency pressure of a background cannot be relieved.
Another existing technical scheme provides a J2EE rapid development platform based on a code generator, and adopts a front-end and back-end separation architecture: SpringBoot2.x, Ant Design & Vue, Mybatis-plus, Shiro, JWT. The powerful code generator enables front and rear end codes to be generated in a one-key mode, and the method does not need to write any codes, supports a user-defined form, supports form dragging configuration, supports a form template and supports large-screen display. The strong form configuration function can generate a form management page without compiling codes, and simple services can be quickly set up. JeecgBoot leads to a new development mode (Online Coding mode- > code generator mode- > manual MERGE intelligent development), helps to solve 70% of repeated work of Java projects, and gives more attention to business logic. The development efficiency can be rapidly improved, the cost is saved, and meanwhile, the failure activity is avoided. However, this method has the following disadvantages: the page can not be used by any combination of the components, and only can be a list page, a form page and a detail page. The list page can only be a fixed table component and layout, is only suitable for a fixed simple service scene, cannot be used for rapidly developing a complex service scene, and is not flexible and abundant. The information management system which is rapidly generated lacks the fusion function with other service systems, cannot be seamlessly butted with other systems or embedded and used by other existing service information systems, and has insufficient expansibility.
