Class AuthenticationProcessingFilterEntryPoint

java.lang.Object
  org.acegisecurity.ui.webapp.AuthenticationProcessingFilterEntryPoint

All Implemented Interfaces:

AuthenticationEntryPoint, InitializingBean

public class AuthenticationProcessingFilterEntryPoint
extends Object
implements AuthenticationEntryPoint, InitializingBean

Used by the SecurityEnforcementFilter to commence authentication via the AuthenticationProcessingFilter. This object holds the location of the login form, relative to the web app context path, and is used to commence a redirect to that form.

By setting the forceHttps property to true, you may configure the class to force the protocol used for the login form to be HTTPS, even if the original intercepted request for a resource used the HTTP protocol. When this happens, after a successful login (via HTTPS), the original resource will still be accessed as HTTP, via the original request URL. For the forced HTTPS feature to work, the PortMapper is consulted to determine the HTTP:HTTPS pairs.

The URL where the AuthenticationProcessingFilter login page can be found. Should be relative to the web-app context path, and include a leading /

Parameters:

loginFormUrl -

getLoginFormUrl

public String getLoginFormUrl()

setPortMapper

public void setPortMapper(PortMapper portMapper)

getPortMapper

public PortMapper getPortMapper()

setPortResolver

public void setPortResolver(PortResolver portResolver)

getPortResolver

public PortResolver getPortResolver()

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:
