Shiro登陆异常 did not match the expected credentials.

错误如下：

 threw exception [Request processing failed; nested exception is org.apache.shiro.authc.IncorrectCredentialsException: Submitted credentials for token [org.apache.shiro.authc.UsernamePasswordToken - admin, rememberMe=true] did not match the expected credentials.] with root cause

解决方案：

1. 这是shiro返回的密码校验结果不一样，要么你把shiro校验的令牌规则重写，就是按什么方式去校验。
2. 要么你自己把密码加密好传给shiro。

• 白话文讲：
  当你登陆的时候，你会创建一个UsernamePasswordToken对象，或者UsernamePasswordToken的子类对象，并且赋予账号、密码、rememberMe，这里的密码你需要和数据库一直，比如你做了md5加密，那么你先做md5加密然后再创建UsernamePasswordToken对象.
  然后你在校验完毕后：

  return new SimpleAuthenticationInfo(token,memberSecurity.getLoginPswd(), getName());

  • 这里的第二个参数为密码，shiro会把第二个参数和你开始传进来的参数按规则对比，如果错误（或者是同一个引用对象）就返回上面的错误。
