前言

关于 pine-manage-system，是用于学习和使用一些java技术，和自己对某些业务的理解与落地的验证。

这是一个多模块项目，里边集成了不少后端常见的功能。

🌈 接口文档

Doc 接口文档：http://localhost:8080/pine-manage/doc.html
Actuator监控地址：http://localhost:8080/pine-manage/actuator
Api导入地址：http://localhost:8080/pine-manage/v3/api-docs

🚀 项目启动

检查java环境，需要使用java17
检查maven是否正常安装，正常使用
数据库初始化，执行 pine-manage.sql
修改配置信息，比如数据库连接信息，redis信息等
启动项目 pine-manage-start 里的启动类 PineManageApplication

如果使用 java -jar 的方式启动，可以采用项目中提供的脚本文件start.bat或 start.sh；注意在启动时，需要将jar包和脚本文件放在同一目录下。

项目功能代码示例

1、数据库拦截器-打印sql执行时间
