hibernate实现多表关联查询的例子
hibernate实现多表关联查询的例子：
1.HQL语句:
select new cn.u6.contoller.bean.UserBean(model1.userId,model1.userName,model1.passWord,model1.isEnable,model2.groupName) from User as model1, Group as model2, UserGroup as model3 where model1.userId=model3.userId and model3.groupId=model2.groupId
?
2.UserBean相当大家所说的VO即值对象，里面必须要有对应的构造方法
?
