Class NoopLogoutService

java.lang.Object

com.svenruppert.jsentinel.logout.NoopLogoutService

All Implemented Interfaces:

LogoutService

public final class NoopLogoutService
extends Object
implements LogoutService

Default LogoutService — discards every call. Returned by JSentinelServiceResolver.logoutService() when no real implementation has been registered.

Production applications must register a concrete SubjectClearingLogoutService (or an adapter-specific subclass) during startup. The noop fallback exists so the resolver never throws — logout is optional infrastructure, like audit.
