-# SpringBoot 项目初始模板
-
-> by [程序员鱼皮知识星球](https://yupi.icu)
-
-Java SpringBoot 项目初始模板，整合了常用框架和示例代码，大家可以在此基础上快速开发自己的项目。
-
-## 模板功能
-
-- Spring Boot 2.7.0（贼新）
-- Spring MVC
-- MySQL 驱动
-- MyBatis
-- MyBatis Plus
-- Spring Session Redis 分布式登录
-- Spring AOP
-- Apache Commons Lang3 工具类
-- Lombok 注解
-- Swagger + Knife4j 接口文档
-- Spring Boot 调试工具和项目处理器
-- 全局请求响应拦截器（记录日志）
-- 全局异常处理器
-- 自定义错误码
-- 封装通用响应类
-- 示例用户注册、登录、搜索功能
-- 示例单元测试类
-- 示例 SQL（用户表）
-
-访问 localhost:7529/api/doc.html 就能在线调试接口了，不需要前端配合啦~
