测试：

@Test
    public void test01() { 
        //1.初始化shiro的安全管理器
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        //2.设置用户的权限信息到安全管理器
        Realm realm = new IniRealm("classpath:shiro.ini");
        securityManager.setRealm(realm);
        //3. 使用SecurityUtils将securityManager设置到运行环境中
        SecurityUtils.setSecurityManager(securityManager);
        //4. 创建一个Subject实例
        Subject subject = SecurityUtils.getSubject();
        //5. 创建用于认证的认证的token，记录用户认证的身份和凭证即账号和密码
        AuthenticationToken token =
                new UsernamePasswordToken("zhangsan", "123456");
        System.out.println("用户认证状态：" + subject.isAuthenticated());
        //6.主体要进行登录，登录的时候进行认证检查
        subject.login(token);
        // 用户认证状态
        System.out.println("用户认证状态：" + subject.isAuthenticated());
        //7.检查角色的授权状态
        System.out.println("是否拥有admin角色: " + subject.hasRole("admin"));
        System.out.println("是否拥有public角色: " + subject.hasRole("public"));
        //8.检查权限的授权状态
        System.out.println("product:view: " + subject.isPermitted("product:view"));
        System.out.println("product:view: " + subject.isPermitted("product:view", "product:update2")[1]);
        //退出
        subject.logout();
        System.out.println("用户认证状态：" + subject.isAuthenticated());
    }
