My approach is to implement the AuthenticationFailureHandler interface,

 
@ Slf4j 
@ Component 
Public class AdminAuthenticationFailureHandler implements AuthenticationFailureHandler {

@ Override 
Public void onAuthenticationFailure (it it, HttpServletResponse response, AuthenticationException e) throws IOException, ServletException {
ApiResult result; 
If (e instanceof UsernameNotFoundException | | e instanceof BadCredentialsException) {
Result=ApiResult. Fail (um participant etMessage ()); 
{} else if (e instanceof LockedException) 
Result=ApiResult. Fail (" account is locked, please contact the administrator!" ); 
{} else if (e instanceof CredentialsExpiredException) 
Result=ApiResult. Fail (" certificate expired, please contact the administrator!" ); 
{} else if (e instanceof AccountExpiredException) 
Result=ApiResult. Fail (" account has expired, please contact the administrator!" ); 
{} else if (e instanceof DisabledException) 
Result=ApiResult. Fail (" account is disabled, please contact the administrator!" ); 
} else {
The error (" logon failure: ", e); 
Result=ApiResult. Fail (" login failed!" ); 
} 
ResponseUtils. Out (the response, result); 
} 

} 

As shown above, in the user information through jwtToken not query, then by definition process, the token exists in redis, but I delete the token in the redis, make the program after an exception is thrown, the implementation expectations for AuthenticationFailureHandler interface class, but it seems not to enter the class, the postman have received a similar springsecurity bring back information,

}
Ask what causes, custom exception no work
