intermediateCustom AuthenticationProvider & Exception Handling
What is the difference between AuthenticationEntryPoint and AccessDeniedHandler, and which HTTP status does each typically produce?
AuthenticationEntryPoint handles AuthenticationException (the caller isn't authenticated at all) and typically results in HTTP 401 Unauthorized. AccessDeniedHandler handles AccessDeniedException (the caller IS authenticated but lacks sufficient permission) and typically results in HTTP 403 Forbidden. Both are invoked centrally by ExceptionTranslationFilter.
