JEECG micro-cloud quick development platform

Latest Version: 3.6.2 (released on: 20160315)

Preface:

As the web ui framework (EasyUI/Jquery UI/Ext/DWZ) Gradually matures, the system interface is gradually unified, and the code generator can also generate a unified and standardized interface! Code Generation + manual MERGE semi-intelligent development will be a new trend. The single-table data model and the addition, deletion, modification, and query function of a pair of multi-data models are directly generated and used, saving 60% of the workload, quickly improve development efficiency !!!

Introduction

JEECG (J2EE Code Generation) is an intelligent development platform based on Code generators. Leading the new development mode (Online Coding mode-> code generator mode-> manual MERGE intelligent development) can help solve the repetitive work of Java project 60%, so that development pays more attention to business logic. It can quickly improve development efficiency, help the company save manpower costs, and at the same time without losing flexibility.

JEECG is designed to provide simple functions configured by generation Online Coding. complex functions are generated by code generators for manual Merge. complicated process businesses are customized by forms, business processes use workflows to implement and expand task interfaces for development and writing of business logic. The flexible configuration of Process Task nodes and task interfaces ensures the confidentiality of the company's processes and reduces the workload of developers.

Applicable Projects

The JEECG quick development platform can be used in the development of any J2EE project. It is especially suitable for enterprise information management system (MIS), internal office system (OA), and enterprise resource planning system (ERP) customer Relationship Management System (CRM), its semi-intelligent manual Merge development method can significantly improve development efficiency by more than 70%, greatly reducing development costs; JEECG particularly supports SAAS enterprise-level application development, and the plug-in mechanism better supports SAAS cloud application requirements.

Why choose JEECG?

• 1. It is easy to get started with the mainstream framework. The code generator has low dependence and convenient scalability, and can fully implement secondary development;
• 2. High development efficiency. The Code Generator, single-table data model, and one-to-many (parent-child table) data model are used to automatically generate the addition, deletion, modification, and query functions. The menu configuration is directly used;
• 3. automatic page verification (required input, digit verification, amount verification, and time space );
• 4. encapsulated basic user permissions, powerful data permissions, data dictionary, and other basic functions, directly used without modification
• 5. Common encapsulation and various tools (such as scheduled tasks, SMS interfaces, email sending, and Excel export) can meet the needs of 80% projects.
• 6. Integrated with simple report tools, it is very convenient to export image reports and data, and can generate pdf, excel, word, and other reports with great convenience;
• 7. the activiti workflow is integrated, and the development of jbpm workflows can be greatly simplified by simply switching the page configuration process. The process trend is drawn using the jbpm process designer, A workflow is basically completed, and only a small amount of java code needs to be written;
• 8. UI tag library, which is a standard encapsulation for web ui. The page uses custom tags for functions: List data display and page verification. labels are simple, clear, and easy to maintain.
• 9. Online process design, using the open-source Activiti process engine, implements online painting processes, Custom forms, forms affiliated, and Business Flow
• 10. query filter: the query function is automatically generated, and the SQL query conditions are dynamically added in the backend. Multiple matching methods are supported (full match/fuzzy query/include query/unmatched query );
• 11. multiple data sources: it is easy to use. You can configure data sources online to easily capture data from other data sources;
• 12. Internationalization: it supports multiple languages and is very convenient to develop international projects;
• 13. Data permissions (refined data permission control, control to row-level, list-level, form field-level, enable different people to view different data, and different people to operate different fields on the same page
• 14. Multiple homepage styles are switched to support custom homepage styles. (Classic style, Shortcut style, ACE bootstrap style, cloud desktop style)
• 15. Online report configuration (no code is required. Online reports such as graphs, bars, and data are implemented through online configuration)
• 16. Easy Excel Import and Export. Single-Table export and one-to-many table export are supported. The generated code comes with the import and export function.
• 17. custom forms: supports custom form la s, single tables, one-to-many forms, select, radio, checkbox, textarea, date, popup, list, macros, and other controls. JEECG Applicability

  The JEECG intelligent development platform can be used in the development of any J2EE project.
