Objective:

With the gradual maturation of the WEB UI Framework (Easyui/jquery UI/EXT/DWZ), the system interface is gradually unified, and the code generator can generate a uniform and standardized interface! Code generation + Manual Merge semi-intelligent development will be a new trend, single-table data model and a one-to-many data model of the deletion and modification of the function directly generated use, can save 60% of the workload, quickly improve development efficiency!!!

Brief introduction

JEECG (Java EE code Generation) is an intelligent development platform based on the code generator. Leading the new development model (Online coding mode, code generator mode, manual merge Intelligent development) can help solve the repetitive work of Java Project 60%, allowing development to focus more on business logic. It can quickly increase development efficiency and help companies save on labor costs without sacrificing flexibility.

JEECG purpose is: simple function by the generation of online coding configuration features, complex functions by the code generator generated by the manual merge; The complex process business uses form customization, and the business process uses workflow to implement and extend the task interface for development and writing business logic. It realizes the flexible configuration of the Process task node and the task interface, which not only guarantees the confidential line of the company's process, but also reduces the workload of the developer.

Applicable projects

JEECG Rapid development platform, can be applied in the development of any EE project, especially suitable for enterprise information Management System (MIS), internal Office System (OA), Enterprise Resource planning system (ERP), Customer Relationship Management System (CRM), its semi-intelligent manual merge Development method, Can significantly improve the development efficiency of more than 70%, greatly reduce development costs; JEECG is particularly supportive of SaaS enterprise application development, and the plug-in mechanism is a better support for SaaS cloud application needs.
