Class ExceptionMappingAuthenticationFailureHandler

java.lang.Object

org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler

org.springframework.security.web.authentication.ExceptionMappingAuthenticationFailureHandler

All Implemented Interfaces:

AuthenticationFailureHandler

public class ExceptionMappingAuthenticationFailureHandler
extends SimpleUrlAuthenticationFailureHandler

Uses the internal map of exceptions types to URLs to determine the destination on authentication failure. The keys are the full exception class names.

If a match isn't found, falls back to the behaviour of the parent class, SimpleUrlAuthenticationFailureHandler.

The map of exception names to URLs should be injected by setting the exceptionMappings property.
