t3用户-角色-权限hibernate经典配置
用户-角色-权限hibernate经典配置。既然有人问起，我就写下说明吧。在文章中间的配置文件那里。权当回忆一下，也帮助更多人。这是以前学校时写的，没有注释。都是贴的代码笔记。看到的莫要见怪。欢迎学习交流。

用户-角色-权限关系如下：
一个用户user对应多个角色role，一个角色对应多个用户，关系为多对多many-to-many
一个角色role对应多个权限functions,一个权限也对应多个角色。
这个自不必说。
主要是如何维护呢。
如下所示：
多对多必然产生中间表进行关联。
user与role产生中间表userRole。则user与userRole的关系为one-to-many。理解为一个用户可以有多个权限对应。role与userRole的关系为one-to-many。理解为一个权限可以有多个用户对应。
其次就是角色role与权限function，中间表为roleFunction,他们之前的关系如上。
只不过role表在中间，即与user表是多对多的关系，又与function表是多对多的关系。所以role会产生2张中间表，一张userRole，一张roleFunction而已。
role与这2张中间表都是one-to-many的关系，反之，它们与role却都是many-to-one的关系。
user->userRole->role->roleFunction->function
user->userRole一对多,role->userRole一对多,则user->role多对多
role->roleFunction一对多，function->roleFunction一对多，则role->function多对多
说白了就是把2个多对多，分解成了4个一对多【其实就是2对一对多】而已。
这样写来。再看配置，则是一目了然了。
