1.springboot集成shiro之登陆加密报错，提示如下：

2.分析经过

主要是这句：java.lang.IllegalArgumentException: Illegal hexadecimal character m at index 0

点进去查看这个地方

进去后debug

查看这个参数，不太对啊，也不是十六进制。

往上debug查看参数是什么，不是加密后的所以错误。

3.结论

在自定义的realm类里的方法doGetAuthenticationInfo处理加密验证的时候，password传成明文的了，应该是密文的。

注意参数：userName明文, password密文。

ByteSource byteSourceSalt = ByteSource.Util.bytes(user.getSalt());
SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(userName, password, byteSourceSalt, getName());
return simpleAuthenticationInfo;
