cms-登陆

先介绍下登陆的思路：

1.在登陆页面首先前端验证用户名和密码是否正确，如果验证通过，则ajax的方式向后台提交数据。

2.在controller层，将得到的用户名名和密码封装进shiro的token，在提交token过程中如果成功则登陆成功，如果出现异常则登陆失败，并且把登陆情况发送回登陆页面

3.controller层执行subject时候调用realm，realm里面有俩个函数，一个验证权限一个验证身份，在此调用验证身份的函数。在token中得到传过来的用户名，根据用户名查询与该用户名对应的数据，

把查询得到的数据与token做对比，如果正确则登陆成功，如果失败则登陆失败，最后将信息存放在session中
