1、shiro授权角色、权限

权限表设计图：

ShiroUserMapper:

Set<String> getRolesByUserId(Integer uid);

    Set<String> getPersByUserId(Integer uid);

ShiroUserMapper.xml：

<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 = #{uid}
</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 = #{uid}
</select>

MyRealm:

前面讲了认证，这次只重写了授权方法

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

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        info.setRoles(roleIds);
        info.setStringPermissions(perIds);

        return info;
    }

然后在测试就好了！

2、Shiro的注解式开发

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

ShiroUserController:

  /**
     * 身份认证
     * @param req
     * @param resp
     * @return
     */
    @RequestMapping("/passUser")
    public String passUser(HttpServletRequest req, HttpServletResponse resp){
        return "admin/addUser";
    }

    /**
     * 角色认证
     * @param req
     * @param resp
     * and : 必须同时具备
     * or:有其一即可
     * @return
     */
    @RequiresRoles(value = {"1","4"},logical = Logical.AND)
    @RequestMapping("/passRole")
    public String passRole(HttpServletRequest req, HttpServletResponse resp){
        return "admin/listUser";
    }

    /**
     *  权限认证
     * @param req
     * @param resp
     * @return
     */
    @RequiresPermissions(value = {"user:update","user:view"},logical = Logical.OR)
    @RequestMapping("/passPer")
    public String passPer(HttpServletRequest req, HttpServletResponse resp){

        return "admin/resetPwd";
    }


    /**
     * 认证失败后的处理请求方式
     * @param req
     * @param resp
     * @return
     */
    @RequestMapping("/unauthorized")
    public String unauthorized(HttpServletRequest req, HttpServletResponse resp){
        System.out.println("错误认证处理！！！");
        return "unauthorized";
    }

在springmvc-servlet.xml添加:

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
          depends-on="lifecycleBeanPostProcessor">
        <property name="proxyTargetClass" value="true"></property>
    </bean>
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
        <property name="securityManager" ref="securityManager"/>
    </bean>

    <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
        <property name="exceptionMappings">
            <props>
                <prop key="org.apache.shiro.authz.UnauthorizedException">
                    unauthorized
                </prop>
            </props>
        </property>
        <property name="defaultErrorView" value="unauthorized"/>
    </bean>

jsp中添加：

<ul>
    shiro注解
    <li>
        <a href="${pageContext.request.contextPath}/passUser">用户认证</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passRole">角色</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passPer">权限认证</a>
    </li>
</ul>

测试：
