SpringMVC+Shiro权限管理
博文目录
- 权限的简单描述
- 实例表结构及内容及POJO
- Shiro-pom.xml
- Shiro-web.xml
- Shiro-MyShiro-权限认证,登录认证层
- Shiro-applicationContext-shiro.xml
- HomeController
- 三个JSP文件
什么是权限呢?举个简单的例子:
我有一个论坛,注册的用户分为normal用户,manager用户。
对论坛的帖子的操作有这些:
添加,删除,更新,查看,回复
我们规定:
normal用户只能:添加,查看,回复
manager用户可以:删除,更新
normal,manager对应的是角色(role)
添加,删除,更新等对应的是权限(permission)
我们采用下面的逻辑创建权限表结构(不是绝对的,根据需要修改)
一个用户可以有多种角色(normal,manager,admin等等)
一个角色可以有多个用户(user1,user2,user3等等)
一个角色可以有多个权限(save,update,delete,query等等)
一个权限只属于一个角色(delete只属于manager角色)
我们创建四张表:
t_user用户表:设置了3个用户
-------------------------------
id + username + password
---+----------------+----------
1 + tom + 000000
2 + jack + 000000
3 + rose + 000000
---------------------------------
t_role角色表:设置3个角色
--------------
id + rolename
---+----------
1 + admin
2 + manager
3 + normal
--------------
t_user_role用户角色表:tom是admin和normal角色,jack是manager和normal角色,rose是normal角色
---------------------
user_id + role_id
-----------+-----------
1 + 1
1 + 3
2 + 2
2 + 3
3 + 3
---------------------
t_permission权限表:admin角色可以删除,manager角色可以添加和更新,normal角色可以查看
-----------------------------------
id + permissionname + role_id
----+------------------------+-----------
1 + add + 2
2 + del + 1
3 + update + 2
4 + query + 3
-----------------------------------

使用SHIRO的步骤:
1,导入jar
2,配置web.xml
3,建立dbRelm
4,在Spring中配置
pom.xml中配置如下:

在spring的配置文件中配置,为了区别spring原配置和shiro我们将shiro的配置独立出来。
