代码延续地址：Shiro+springboot+mybatis(md5+salt+散列）认证与授权-01
1.创建t_role角色表(比如管理员admin，普通用户user等），创建t_pers权限表（比如add,update,delete等），t_user_role与t_role_pers作为三个表的中间表（因为这三个表之间是多对多的关系)
2.UserMapper.xml新增sql查询
<select id="findByRolesUserName" parameterType="String" resultMap="userMap">
select u.id uid,u.username,r.id rid,r.name
from t_user u
left join t_user_role ur
on u.id=ur.userId
left join t_role r
on ur.roleId=r.id
where u.username=#{username};
</select>
<select id="findPermsByRoleId" parameterType="String" resultType="com.hao.springboot.entity.Pers">
select p.id,p.name,p.url,r.name
from t_role r
left join t_role_pers rp
on r.id=rp.roleId
left join t_pers p
on p.id=rp.persId
where r.id=#{id}
</select>
3.UserDao新增方法
//根据用户名查询所有角色
User findByRolesUserName(String username);
//根据角色id查询权限集合
List<Pers> findPermsByRoleId(String id);
4.Service层新增方法（接口代码省略）
@Override
public User findByRolesUserName(String username) {
return userDao.findByRolesUserName(username);
}
@Override
public List<Pers> findPermsByRoleId(String id) {
return userDao.findPermsByRoleId(id);
}
5.改变自定义realm
/**
* @author:抱着鱼睡觉的喵喵
* @date:2020/12/29
* @description: 自定义realm完成用户认证和授权
*/
public class CustomerRealm extends AuthorizingRealm {
/**
* 用户授权
* @param principalCollection
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("调用权限认证："+principalCollection);
String primaryPrincipal = (String) principalCollection.getPrimaryPrincipal();
//调用身份信息获取角色和权限信息
UserService userService = (UserService) ApplicationContextUtils.getBean("userService");
//根据主身份获取角色和权限信息
User users = userService.findByRolesUserName(primaryPrincipal);
//授权角色信息
if (!CollectionUtils.isEmpty(users.getRoles())){
SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
users.getRoles().forEach(role -> {
simpleAuthorizationInfo.addRole(role.getName());
List<Pers> perms = userService.findPermsByRoleId(role.getId());
if (!CollectionUtils.isEmpty(perms)){
perms.forEach(pers -> {
simpleAuthorizationInfo.addStringPermission(pers.getName());
});
}
});
return simpleAuthorizationInfo;
}
return null;
}
/**
* 用户认证
* @param authenticationToken
* @return
* @throws AuthenticationException
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
String principal = (String) authenticationToken.getPrincipal();
//在工厂中获取业务对象
UserService userService = (UserService) ApplicationContextUtils.getBean("userService");
User user = userService.findByUserName(principal);
if (!ObjectUtils.isEmpty(user)){
return new SimpleAuthenticationInfo(user.getUsername(),user.getPassword(), ByteSource.Util.bytes(user.getSalt()),this.getName());
}
return null;
}
}
