insert into roles(role_name) values('项目经理');
insert into roles(role_name) values('测试人员');

• 角色-权限数据

--超级管理员权限
insert into role_permission values(1,1);
insert into role_permission values(1,2);
insert into role_permission values(1,3);
insert into role_permission values(1,4);
insert into role_permission values(1,5);
insert into role_permission values(1,6);
insert into role_permission values(1,7);
insert into role_permission values(1,8);
insert into role_permission values(1,9);
insert into role_permission values(1,10);
insert into role_permission values(1,11);
insert into role_permission values(1,12);
insert into role_permission values(1,13);
insert into role_permission values(1,14);
insert into role_permission values(1,15);
--测试人员权限
insert into role_permission values(3,1);
insert into role_permission values(3,7);
insert into role_permission values(3,14);
insert into role_permission values(3,15);

• 用户数据

insert into users(username,password) values('admin','admin1234');
insert into users(username,password) values('guet','guet1234');

• 用户-角色数据

insert into user_role values(1,1);
insert into user_role values(2,3);

如果此时用户是guet，写一条SQL来获取guet 的所有菜单

--涉及多表查询
select p.*
from users u,user_role ur,roles r,permissions p,role_permission rp
where u.user_id=ur.user_id and ur.role_id=r.role_id and
r.role_id=rp.role_id and p.permission_id=rp.permission_id
and u.username='guet'

后端代码运行

利用Generator快速生成SpringMVC框架中的相关代码

• 配置applicationContext.xml
  
• Generator函数生成
  
  

创建SQL语句

• 查找用户guet的所有菜单

select p.*
from users u,user_role ur,roles r,permissions p,role_permission rp
where u.user_id=ur.user_id and ur.role_id=r.role_id and
r.role_id=rp.role_id and p.permission_id=rp.permission_id
and u.username='guet'

• 在UserMapper中添加getPermissionByUsername()方法
  
• 在xml文件中实现该方法
  

创建UserController

• 调用getPermissionByUsername()进行查询

• 配置applicationContext.xml
  

Postman进行测试

• 结果：

• 发现数据不全，解决如下
  resultType换成resultMap="cn.edu.guet.mapper.PermissionMapper.BaseResultMap"
  
  结果如下：
