Shiro入门2

在上一篇博文中，通过ssm+shiro，可以实现对页面的访问控制，user:"zhang3"角色是"admin",但是没有给他分配"productManager"的角色，所以他可以访问"查看产品","删除订单",但是访问"删除产品"时会提示

而user：“li4”拥有"productManager"的角色，所以他可以访问"删除产品",却不能访问"删除订单"。

这样一来就实现了权限的分配。

但是这个权限的分配过程，是通过在控制器对应方法上添加@RequirePermission和@RequiredRoles注解实现的。

真正项目开发的时候，这种方式就很有局限性了，当权限配置关系发生变化，每次都要修改代码，编译打包重启系统，这肯定是不能够被接受的。
所以，最好的方式，还是通过动态配置，哪个给不同的用户配置不同的角色，权限，修改之后立马生效这种方式。为了实现这个效果，就需要基于URL配置的方式来做了。

接下来要做基于URL配置权限的讲解。但是基于URL配置权限需要自己能够进行权限信息的灵活配置，那么就需要对权限信息一套进行维护。

到这里先看一下整个项目的结构:

1.对表结构进行调整

主要是增加了一些字段

 1 DROP DATABASE IF EXISTS shiro;
 2 CREATE DATABASE shiro DEFAULT CHARACTER SET utf8;
 3 USE shiro;
 4    
 5 drop table if exists user;
 6 drop table if exists role;
 7 drop table if exists permission;
 8 drop table if exists user_role;
 9 drop table if exists role_permission;
10    
11 create table user (
12   id bigint auto_increment,
13   name varchar(100),
14   password varchar(100),
15   salt varchar(100),
16   constraint pk_users primary key(id)
17 ) charset=utf8 ENGINE=InnoDB;
18    
19 create table role (
20   id bigint auto_increment,
21   name varchar(100),
22   desc_ varchar(100),
23   constraint pk_roles primary key(id)
24 ) charset=utf8 ENGINE=InnoDB;
25    
26 create table permission (
27   id bigint auto_increment,
28   name varchar(100),
29   desc_ varchar(100),
30   url varchar(100), 
31   constraint pk_permissions primary key(id)
32 ) charset=utf8 ENGINE=InnoDB;
33    
34 create table user_role (
35   id bigint auto_increment,
36   uid bigint,
37   rid bigint,
38   constraint pk_users_roles primary key(id)
39 ) charset=utf8 ENGINE=InnoDB;
40    
41 create table role_permission (
42   id bigint auto_increment,
43   rid bigint,
44   pid bigint,
45   constraint pk_roles_permissions primary key(id)
46 ) charset=utf8 ENGINE=InnoDB;

1.listUser.jsp

2.editUser.jsp

3.listRole.jsp

4.editRole.jsp

5.listPermission.jsp
