1. Old group was taken down, new group:

This version significantly improves the usability of the workflow, as follows:

Introduced designer support, added support for Solon.
Added listener SpEL expression support with extensibility.
Added global listeners for the entire system, accessible via interface.
Process variable expressions now support collection replacement.

2. Detailed Updates:

  • Changelog

  • [feat] Added SpEL expression support for listeners with extensibility.

  • [feat] Added global listeners for the entire system, accessible via interface.

  • [feat] Added an API to retrieve current assignees before approval, similar to Satoken style @huangjian

  • [feat] Process variable expressions now support collection replacement @huangjian

  • [feat] Designer introduction, added support for Solon.

  • [feat] Added default node initialization when creating process definitions.

  • [feat] Added API to query process instance collections based on process definition ID sets.

  • [update] Modified process variable passing method; subsequent assignees can now be initialized via assignee variable expressions or assignment listeners.

  • [update] Removed lazy loading for handler loading; refactored test project.

  • [update] Removed strategy prefix from assignee variable expressions; distinguished by $ and #.

3. Project Introduction

Warm-Flow is a domestic workflow engine🎉, characterized by its simplicity, lightweight design, and extensibility. It is a workflow that can integrate a designer via JAR.

  1. Simple and Easy to Use: Only 7 tables, minimal code, quick to learn and integrate.

  2. Approval Functions: Supports pass, return, arbitrary jump, transfer, termination, countersign, vote sign, delegation, add/reduce sign, mutual exclusion, and parallel gateways.

  3. Listeners and Process Variables: Supports four types of listeners with varying granularity, SpEL expressions, flexibility, extensibility, parameter passing, and dynamic permissions.

  4. Flowchart: The workflow engine includes a built-in flowchart and can be used without integrating a designer.

  5. Process Designer: Can be quickly integrated into projects via JAR, reducing tedious code migration and adaptation. Supports Solon and Spring Boot.

  6. Condition Expressions: Built-in common and SpEL condition expressions, with support for custom extensions.

  7. Assignee Variable Expressions: Built-in ${handler} and SpEL format expressions to meet various scenarios, flexible and extensible.

  8. ORM Framework Extensions: Currently supports MyBatis, MyBatis-Plus, MyBatis-Flex, and JPA. Community will provide support for others in the future; easy to extend.

  9. Database Support: Currently supports MySQL, Oracle, and PostgreSQL. Support for other or domestic databases will be added later.

  10. Multi-Tenancy and Soft Delete: The workflow engine maintains its own multi-tenancy and soft delete implementation, but can also use the corresponding ORM framework's methods.

  11. Supports both Spring and Solon.

  12. Compatible with Java 8 and Java 17 (theoretically Java 11 as well).

  13. Officially provides a practical project based on Ruoyi-Vue encapsulation.
