Answer 1

org.hibernate.MappingException: entity class not found: LoginModel
说的比较清楚啦 看看类在不在，类名字和映射文件名一致嘛？先检查看看

Answer 2

如果把映射文件放在src目录下，就能JSP就能显示数据，可是外面的删掉的话，就报上面的错误！

Answer 3

我想到了很多可能出现的错误：包、配置文件……
却没想到的是 LoginModel.hbm.xml中的
<class name="org.yuboo.hibernate.model.LoginModel" table="login" catalog="mydb">自动生成的为
<class name="LoginModel" table="login" catalog="mydb">忙碌了好久，才搞定！！！！！！！！！！！

Answer 4

嗯，自动生成的不会加包名，工具总有些小BUG，<hibernate-mapping package="org.yuboo.hibernate.model">也可以这样指定包名~
