Class AbstractAuthenticationTargetUrlRequestHandler

java.lang.Object
  org.springframework.security.web.authentication.AbstractAuthenticationTargetUrlRequestHandler

Direct Known Subclasses:

SimpleUrlAuthenticationSuccessHandler, SimpleUrlLogoutSuccessHandler

public abstract class AbstractAuthenticationTargetUrlRequestHandler
extends Object

Base class containing the logic used by strategies which handle redirection to a URL and are passed an Authentication object as part of the contract. See AuthenticationSuccessHandler and LogoutSuccessHandler, for example.

Uses the following logic sequence to determine how it should handle the forward/redirect

• If the alwaysUseDefaultTargetUrl property is set to true, the defaultTargetUrl property will be used for the destination.
• If a parameter matching the targetUrlParameter has been set on the request, the value will be used as the destination.
• If the useReferer property is set, the "Referer" HTTP header value will be used, if present.
• As a fallback option, the defaultTargetUrl value will be used.

setTargetUrlParameter

public void setTargetUrlParameter(String targetUrlParameter)
