授权

Mapper

  Set<String> getRolesByUserId(@Param("userid") Integer userid);

    Set<String>  getPersByUserId(@Param("userid") Integer userid);

<select id="getRolesByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
  select r.roleid from t_shiro_user u,t_shiro_user_role ur,t_shiro_role r
    where u.userid = ur.userid and ur.roleid = r.roleid
    and u.userid = #{userid}
</select>
  <select id="getPersByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
  select p.permission from t_shiro_user u,t_shiro_user_role ur,t_shiro_role_permission rp,t_shiro_permission p
  where u.userid = ur.userid and ur.roleid = rp.roleid and rp.perid = p.perid
  and u.userid = #{userid}
</select>

service层：

 public Set<String> getRolesByUserId(Integer userId);

    public Set<String> getPersByUserId(Integer userId);

@Service("shiroUserService")
public class ShiroUserServiceImpl implements ShiroUserService {
    @Autowired
    private ShiroUserMapper shiroUserMapper;

    @Override
    public Set<String> getRolesByUserId(Integer userId) {
        return shiroUserMapper.getRolesByUserId(userId);
    }

    @Override
    public Set<String> getPersByUserId(Integer userId) {
        return shiroUserMapper.getPersByUserId(userId);
        }
        }

重写自定义realm中的授权方法

 /**
     * 授权
     *
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String uname = principalCollection.getPrimaryPrincipal().toString();
        ShiroUser shiroUser = this.shiroUserService.queryByName(uname);
        Set<String> perids = this.shiroUserService.getPersByUserId(shiroUser.getUserid());
        Set<String> roleIds =this.shiroUserService.getRolesByUserId(shiroUser.getUserid());
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        info.setRoles(roleIds);
        info.setStringPermissions(perids);

        return info;
    }

注解式开发

常用注解介绍

@RequiresAuthenthentication:表示当前Subject已经通过login进行身份验证;即 Subject.isAuthenticated()返回 true

  @RequiresUser:表示当前Subject已经身份验证或者通过记住我登录的

  @RequiresGuest:表示当前Subject没有身份验证或者通过记住我登录过，即是游客身份

  @RequiresRoles(value = {"admin","user"},logical = Logical.AND):表示当前Subject需要角色admin和user

  @RequiresPermissions(value = {"user:delete","user:b"},logical = Logical.OR):表示当前Subject需要权限user:delete或者user:b

注解的使用

 @RequiresUser
    @ResponseBody
    @RequestMapping("/passUser")
    public String passUser() {
        return "身份认证成功";
    }
@RequiresRoles(value={"1","4"},logical = Logical.OR)
    @ResponseBody
    @RequestMapping("/passRole")
    public String passRole() {
        return "角色认证成功";
    }
@RequiresPermissions(value={"user:update","user:create"},logical = Logical.AND)
    @ResponseBody
    @RequestMapping("/passPer")
    public String passPer() {
        return "权限认证成功";
    }
