Abnormal details:
DoGetAuthenticationInfo in the implementation of the method of the custom realm, with NullPointerException exception information
Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - zhangsan,
rememberMe=false]. Possible unexpected error?
(Typical or expected login exceptions should extend from AuthenticationException).
the reason:
Many emergence of this unusual reason, certainly not because of wrong password, the password is wrong because it will not throw an exception at this point.
I encountered this entity because UserModel model class does not implement the serialization interface, the Serializable; implement this interface after the problem is solved.
