1. Project Overview

AJ-Gaea is a completely open-source low-code platform.

Origin of the Name

Gaea is the Earth goddess in Greek mythology and the mother of the gods. She possesses infinite creative power.

Introduction to Gaea

Gaea is a JavaEE microservices architecture platform built using the classic technology stack (SpringBoot, SpringCloud, Vue, ElementUI). It currently provides two architectures: monolithic and microservices. Built-in basic features include organizational structure, permission management (Users，Roles，Menu, etc.), system management (Data Dictionaries，Parameter Maintenance，Operation log, etc.), message management, component center (Advanced Search / Custom Column Examples), and export center.

4. Feature Overview

Advanced Technology

Built with the most popular technologies: SpringBoot, SpringCloud, Vue, and Element.

Rich Components

A development platform that includes both front-end and back-end code implementations, along with a foundation framework and rich functional components, such as message push notifications, audit logs, data archiving, export components, and API rate limiting.

Functionally complete

Includes a complete built-in permission architecture, covering menus, roles, users, dictionaries, parameters, monitoring, code generation, and other standard system modules.

System Features

1. The latest and most stable technology stack;

2. High development efficiency. The code generator can generate front-end and back-end code with one click, enabling rapid creation of management interface CRUD APIs;

3. Rich components. Functional components for permissions, archiving, logging, exporting, message push notifications, and more;

4. Strong extensibility. Supports advanced user queries and customizable column interfaces;

Built-in functions

1. Organizational Structure: Configure the system's organizational structure;

2. Permission Management: Includes functions related to permissions, menus, roles, and users;

3. System Management: Includes dictionary management, parameter management, help center, and operation logs;

4. Message Management: Includes message sending and receiving overview and push notification functions;

5. Component Center: Primarily provides examples of advanced search/custom columns and front-end and back-end CRUD components;

6. Export Center: Consolidated information about files exported from the system;

7. Provides project initialization Maven archetypes and an operation manual

8. Code Generation: Generate front-end and back-end code with one click. Supports automatic generation of single-table create, delete, update, query, and detail pages, as well as parent-child table detail pages. The UI supports internationalized versions.

9. The UI provides internationalization management functionality
