Shiro授权及注解式开发

一、shiro授权角色、权限

shiro权限设计表:

Service

 /**
     * 根据用户id查询角色(用于角色验证)
     * @param uid
     * @return
     */
    Set<String> getRolesByUserId(Integer uid);

    /**
     * 根据用户id查询权限(用于权限判断)
     * @param uid
     * @return
     */
    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>

重写MyRealm中的授权方法

 

 /**
     * 授权
     * @param principals
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        ShiroUser shiroUser = this.shiroUserService.queryByName(principals.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;
    }

 

二、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

 

注解的使用

 

ShrioUserController

 /**
     * 身份认证的注解
     * @param shiroUser
     * @param req
     * @param resp
     * @return
     */
    @RequestMapping("/passUser")
    public String passUser(ShiroUser shiroUser, HttpServletRequest req, HttpServletResponse resp) {

        return "admin/addUser";
    }

    /**
     * 角色认证的注解
     * @param shiroUser
     * @param req
     * @param resp
     *
     * 当前方法必须同时具备1、4的角色id，才能被访问
     * @return
     */
    @RequiresRoles(value = {"1","4"},logical = Logical.AND)
    @RequestMapping("/passRoles")
    public String passRoles(ShiroUser shiroUser, HttpServletRequest req, HttpServletResponse resp) {

        return "admin/listUser";
    }

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

        return "admin/resetPwd";
    }

    /**
     * 如果身份、角色、权限认证失败后的处理方式
     * @param shiroUser
     * @param req
     * @param resp
     * @return
     */
    @RequestMapping("/unauthorized")
    public String unauthorized(ShiroUser shiroUser, HttpServletRequest req, HttpServletResponse resp) {

        System.out.println("错误认证处理方案");
        return "login";
    }

 

在Springmvc-servlet.xml中添加

 

 

<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>

 

main.jsp

<ul>
    shiro注解
    <li>
        <a href="${pageContext.request.contextPath}/passUser">身份认证</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passRoles">角色认证</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passPer">权限认证</a>
    </li>

</ul>
