本文介绍如何在Eclipse中通过Maven搭建Spring和Hibernate的联合开发环境。首先确保正确安装并配置Spring和Maven，接着基于之前Spring项目的基础上引入Hibernate，详细讲解项目目录结构和必要的配置文件如beans.xml、hibernate.cfg.xml。同时，提到了关键的代码文件如User.java、HibernateUtil.java等，并强调了正确导入和配置Hibernate及MySQL的依赖包。在完成所有设置后，调整数据库连接，运行HelloProgram.java进行测试。适合初学者跟随步骤实践，遇到问题耐心检查配置，多尝试即可解决。

先按照步骤创建一个这个项目，如果你选的没有我的选项你进去百度一下怎么把spring和Maven安装到ecplise上，如果都有的话你就可以直接按照步骤做了是否建立正确看图标画了一个M 和S。只有建立正确的项目下面架包里面你才不会出错。

这里这个beans.xml是我自己加的新建好的项目要有除了 beans.xml 外的所有东西。

我这个案例是基于我上一篇文章 “第一个Spring项目"做出来的在那个基础之上把Hibernate添进去了；

话不多说先上项目目录

这个是项目目录

这里我在说一下我的开发工具是 Ecplise 数据库是mysql Ecplise的东西放到MyEcplise里面也是能用的。

然后就没啥好说的了开始贴代码吧

为了方便看，我把那个类名字写大点这个顺序也是从上往下贴的
