JEECG BOOT Low Code Development Platform

Current version: 3.7.1 (Release date: 2024-09-12)

Project introduction

Java Low Code Platform for Enterprise web applications

JeecgBoot is a low code development platform based on code generators! Front and back end separation architecture SpringBoot2.x, SpringCloud, Ant Design&Vue, Mybatis plus, Shiro, JWT, support for microservices. The powerful code generator makes the front and back end of the code generation, low code development! JeecgBoot leads a new low-code development paradigm (OnlineCoding-> Code Generator -> Manual MERGE) that helps resolve 70% of the duplication in Java projects and makes development more business-focused. Not only can quickly improve efficiency, save research and development costs, but also do not lose flexibility!

JeecgBoot provides a series of low code modules to make Online development truly zero code: Online form development, online reports, report configuration capabilities, online chart design, large screen design, mobile configuration capabilities, form designer, online design flow, process automation configuration, plug-in capabilities (pluggable) and more!

The purpose of JEECG is: simple functions are implemented by OnlineCoding configuration, so that zero code development; Complex functions are generated by code generator and manually Merge to achieve low code development, which ensures both intelligence and flexibility. The implementation of low code development and support flexible coding at the same time, to solve the current low code products are generally not flexible drawbacks!

JEECG Business process: Using workflow to implement and extend the task interface for developing and writing business logic, forms provides a variety of solutions: form designer, online configuration form, and coding form. At the same time, the separation design of process and form (loose coupling) is realized, and the flexible configuration of task nodes is supported, which not only ensures the confidentiality of the company's process, but also reduces the workload of developers.

Why JeecgBoot?

Adopt the latest mainstream front and back separation framework (Springboot+Mybatis+antd), easy to use; Code generator has low dependency, flexible expansion ability, and can quickly realize secondary development;
Support microservices SpringCloud Alibaba(Nacos, Gateway, Sentinel, Skywalking), and provide switching mechanism to support free switching between single and microservices
High development efficiency, using code generator, single table, tree list, one-to-many, one-to-one and other data models, add, delete, change and search function one-key generation, menu configuration directly use;
Code generator provides powerful template mechanism, support custom template, currently provide four sets of style template (single table two sets, tree model one set, one to many three sets)
Code generator is very intelligent, online business modeling, online configuration, WYSIWYG support 23 kinds of controls, a key to generate front and back end code, greatly improve the development efficiency, no longer worry about repeated work.
Low code ability: Online online form (without coding, through online configuration of the form, to achieve the addition, deletion, change and check of the form, support single table, tree, one-to-many, one-to-one model, to achieve everyone can code)
Low code ability: Online online report (without coding, through online configuration, to achieve data report, can quickly extract data, reduce development pressure, to achieve everyone can code)
Low code ability: Online online chart (without coding, through online configuration, to achieve graphs, bar graphs, data reports, etc., support custom layout, to achieve everyone can code)
