# 系统配置与审计通知中心实施计划

> **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）的数据库持久化与功能完善

**Architecture:** 基于Spring R2DBC响应式架构，遵循现有分层模式（Handler->Service->Repository->Entity），使用H2/PostgreSQL + Caffeine缓存，消息推送采用WebSocket

**Tech Stack:** Spring WebFlux, Spring Data R2DBC, H2/PostgreSQL, Caffeine, WebSocket, Lombok

import org.springframework.data.annotation.Id;
import org.springframework.data.relational.core.mapping.Column;
import org.springframework.data.relational.core.mapping.Table;

@Table("sys_dict_type")
public class SysDictTypeEntity {

    @Id
    private Long id;

    @Column("dict_name")
    private String dictName;

    @Column("dict_type")
    private String dictType;

    @Column("status")
    private String status;

    @Column("remark")
    private String remark;

    @Column("created_at")
    private LocalDateTime createdAt;

    @Column("updated_at")
    private LocalDateTime updatedAt;

    @Column("deleted_at")
    private LocalDateTime deletedAt;
