Spring MVC + Spring + Hibernate + mysql 注册登陆入门实例
Spring MVC + Spring + Hibernate + mysql 注册登陆入门实例
（1） 结构
（说明目的是要做在线聊天室的，也包含登陆注册部分，先用这部分做个例子）开发环境用的是STS（spring tool suite）基于Eclipse开发的spring整合开发环境。
主要的几个文件说明：userbean.java 用户的bean文件，userbean.hbm.xml是他的hibernate映射文件。application-config.xml文件是spring的配置文件，里面包含数据源配置（连数据库），bean设置等。mvc-config.xml文件是springmvc 的配置文件。
（2）代码
userbean.java

（3）效果截图
注册页面
提交后数据库显示
（4）其他
注册页面还包含邮箱验证等，关于在线聊天室的开始会在这个的基础上后期进行开发。
