Spring Security：如何从 <sec:form-login> 标签

Question

Hi I'm trying to get the login-page value from the <sec:form-login> that can be set in the application-context.xml :

<beans>
...
<sec:form-login login-page="/login.html" 
    authentication-failure-url="/failed.html"
    default-target-url="/secure/index.jsp" />
...
</beans>

Eg I've got a KerberosFailureHandler which implements the AuthenticationFailureHandler Interface. This handler should redirect to the loginpage that is configured in my application-context.xml. But I don't know how to get the parameter. Is it possible to inject the value with an @Autowired or something?

I think the normal way to do that would be to extract the login page value to an external configuration (eg properties file, but it could be in .java just as well, especially if you use @Configuration ). Then inject the same value into the AuthenticationFailureHandler and the login configuration.
