        Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:shiro.ini");
        // 获取securityManager实例
        SecurityManager securityManager=factory.getInstance();
        // 把securityManager实例绑定到SecurityUtils
        SecurityUtils.setSecurityManager(securityManager);
        // 得到当前执行的用户
        Subject currentUser=SecurityUtils.getSubject();
        // 创建token令牌，用户名/密码
        UsernamePasswordToken token=new UsernamePasswordToken("root", "123456");
        try{
            // 身份认证
            currentUser.login(token);    
            System.out.println("身份认证成功！");
        }catch(AuthenticationException e){
            e.printStackTrace();
            System.out.println("身份认证失败！");
        }
        // 退出
        currentUser.logout();
    }
}
