我是靠谱客的博主开放荔枝，最近开发中收集的这篇文章主要介绍SpringBoot，Maven集成JSP简单实现用户登录，列表增删改查，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

SpringBoot，Maven集成JSP简单实现用户登录，列表增删改查

- 项目结构
- pom.xml
- springboot启动类
- controller
- entity
- mapper
- service 及实现
- applicati.xml
- mapper.xml
- 前端：login.jsp
- userAdd.jsp
- userEdit.jsp
- userList.jsp

只是简单实现了SpringBoot，Maven集成JSP的一个基本项目，仅做学习。有不对的地方请大佬指正

项目结构

在这里插入图片描述

pom.xml

大部分包其实不需要，根据自己需求选择即可
