系统配置、审计通知与WebSocket完整实施计划

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

Goal: 完成系统配置（字典管理、系统参数）、审计中心（登录日志、操作日志、异常追踪）、通知中心（系统公告、消息推送WebSocket）、文件管理（上传/下载/预览）的完整功能实现，包括数据库持久化、REST API、WebSocket实时推送和E2E测试验证

Architecture: 基于Spring WebFlux响应式架构，遵循现有分层模式（Handler->Service->Repository->Dao->Entity），使用PostgreSQL + R2DBC，消息推送采用WebSocket，文件预览支持多种格式

Tech Stack: Spring WebFlux 3.4.1, Spring Data R2DBC, PostgreSQL, WebSocket, Lombok, Reactor

第一阶段：Repository层（8个Repository）

第五阶段：修复E2E测试认证问题

Task 19: 检查并修复SecurityConfig

Files:

Modify: config/SecurityConfig.java

Step 1: 检查SecurityConfig配置

查看现有SecurityConfig，确保：

JWT认证过滤器正确配置
受保护端点需要认证
公开端点（如登录、注册）允许匿名访问

Step 2: 更新SecurityConfig（如需要）

根据实际情况调整配置，确保：

/api/auth/** 允许匿名访问
/ws/** 允许匿名访问（WebSocket）
其他端点需要认证

Step 3: 编译验证

Run: cd novalon-manage-api/manage-sys && mvn clean compile

Expected: BUILD SUCCESS

Step 4: 提交

git add config/SecurityConfig.java
git commit -m "fix: 修复SecurityConfig认证配置"

Task 20: 运行E2E测试验证

Files:

Test: e2e_tests/

Step 1: 启动后端服务

Run: cd novalon-manage-api/manage-sys && mvn spring-boot:run

Expected: 服务启动成功，监听8080端口

Step 2: 运行E2E测试

在另一个终端运行：

Run: cd e2e_tests && pytest -v

Expected: 测试执行，显示通过/失败结果

Step 3: 检查测试结果

查看测试报告，重点关注：

认证测试是否通过
用户管理测试是否通过
角色管理测试是否通过
字典管理测试是否通过
系统配置测试是否通过
通知公告测试是否通过
文件管理测试是否通过
审计日志测试是否通过

Step 4: 修复失败的测试（如有）

根据测试失败原因，修复相关代码：

API端点不匹配：更新测试用例或Handler
响应格式不一致：调整Handler返回格式
认证问题：检查SecurityConfig和JWT配置

Step 5: 重新运行测试

Run: cd e2e_tests && pytest -v

Expected: 所有测试通过

Step 6: 生成测试报告

Run: cd e2e_tests && pytest --html=report.html --self-contained-html

Expected: 生成HTML测试报告

Step 7: 提交测试修复

执行总结

本计划共包含23个任务，分为6个阶段：

Repository层（Task 1-8）：创建8个缺失的Repository
Handler层（Task 9-12）：创建4个缺失的Handler
WebSocket消息推送（Task 13-16）：实现WebSocket配置、处理器和服务
Service层集成（Task 17-18）：集成WebSocket到Notice和UserMessage服务
E2E测试验证（Task 19-20）：修复认证问题并运行测试
最终验证与文档（Task 21-23）：编译验证、更新文档、生成总结报告

预计总时间: 3-4小时

关键里程碑:

Task 8: Repository层完成
Task 12: Handler层完成
Task 16: WebSocket功能完成
Task 20: E2E测试全部通过
Task 23: 文档和总结完成

Plan complete and saved to docs/plans/2026-03-12-system-config-audit-notice-websocket-complete-plan.md.

Two execution options:

1. Subagent-Driven (this session) - I dispatch fresh subagent per task, review between tasks, fast iteration

2. Parallel Session (separate) - Open new session with executing-plans, batch execution with checkpoints
