4. Feature Overview

The Snail administration backend is an evolved version of RuoYi/RuoYi-Cloud. It supports multiple tenants, distributed locks, message queues (Kafka, RabbitMQ), workflow approval (flowable), data permissions, and various other functional scenarios, providing an out-of-the-box experience.Built-in WMS management system.

Built-in functions

1. User Management: Users are system operators, this function mainly completes system user configuration.
2. Department Management: Configuring system organizational structures (companies, departments, teams), tree structure presentation supports data permissions.
3. Position Management: Configure system users' positions.
4. Menu Management: Configure system menus, operation permissions, button permissions, etc.
5. Role Management: Role menu permission distribution, set role data range permissions by organization.
6. Dictionary Management: Maintain some fixed data frequently used in the system.
7. Parameter Management: Dynamically configure common parameters in the system.
8. Notification Announcement: System notification and announcement information release and maintenance.
9. Operation Log: Record and query system normal operation logs; record and query system abnormal information logs.
10. Login Log: Record and query system login logs, including login exceptions.
11. Online Users: Monitor the status of active users in the system.
12. Scheduled Tasks: Online (add, modify, delete) task scheduling, including execution result logs.
13. Code Generation: Generate front-end and back-end code (java, html, xml, sql) supporting CRUD download.
14. System Interface: Automatically generate API interface documents based on business code.
15. Service Monitoring: Monitor current system CPU, memory, disk, stack, etc. related information.
16. Online Builder: Drag and drop form elements to generate corresponding HTML code.
17. Connection Pool Monitoring: Monitor the current system database connection pool status, and analyze SQL to find system performance bottlenecks.
18. Serial Number Management: Maintenance of serial number generation rules.
19. MQ Message Management: Records and manages MQ message production and consumption processes, as well as handles abnormal messages.
20. Multi-Tenant Management:

• Data Isolation: Queries different data based on tenants and partitions table data to achieve data isolation.
• Database Isolation: Connects to different databases based on tenants to achieve database isolation.

5. Tech Stack

Snail is a fully open-source rapid development platform, evolved from the RuoYi/RuoYi-Cloud base version into the Snail platform.

• Adopts a frontend-backend separation architecture. The microservices version frontend is (Snail-Antdv).
• The backend uses Spring Boot and Spring Cloud & Alibaba.
• Nacos is used as the service registry and configuration center, while Redis is used for authentication and authorization.
• Sentinel is used for traffic control, and Seata is used for distributed transactions.
• Kafka and RabbitMQ are used as message middleware.
• Flowable is used as the workflow engine.
