Class ExceptionTranslationFilter

java.lang.Object

com.codename1.backend.security.ExceptionTranslationFilter

All Implemented Interfaces:

SecurityFilter

public final class ExceptionTranslationFilter
extends Object
implements SecurityFilter

Turns the security exceptions thrown by what follows it -- the authorization rules, a controller, a service the controller calls -- into answers.

• An AuthenticationException goes to the AuthenticationEntryPoint: a 401 with a challenge, or a redirect to the login page.
• An AccessDeniedException for an anonymous caller goes there too, after the address is remembered, because the remedy is to sign in.
• An AccessDeniedException for a signed-in caller goes to the AccessDeniedHandler: 403.

Anything else is not this filter's and is thrown on.
