HTTPSESSION Returó el objeto NULL para Spring_Security_Context

Question

Estoy tratando de integrar el Spring Saml Library en una aplicación web de muestra, utilizando Shibboleth como IDP. Soy capaz de cargar la página de inicio de sesión, para iniciar sesión y mostrar la página de índice.

El problema es que cuando haga clic en Otros Enlaces, la WebApp me redirige a la página de inicio de sesión, entonces el IDP me reconoce y redirige a la página solicitada (si la red es rápida, es muy difícil ver esto). Es como si no hubiera iniciado sesión para Spring Security.

Revisé el registro y encontré esto:

org.springframework.security.web.context.httpsessionsecuritycontextrepository - httpsession devuelto el objeto null para Spring_Security_Context org.springFramework.security.web.context.httpsessionsecurityContextrepository - Ningún SecurityContext estaba disponible en la sesión HTTPSESSION: org.apache.catalina.session.standardsessionfacade@fde8fb. Se creará una nueva.

Este es el web.xml

Answer 1

He experimentado el mismo problema.Después de la depuración se dio cuenta de que SecurityContext se borra antes de que esté persistido.Después de googling encontré esto: https://jira.springsurce.org/browse/sec-2027 Mudarse a la versión de seguridad de primavera 3.1.2 resolví para mí.

Espero que ayude a alguien.

If you are not particular about using Spring, or you can try something that works first and move to Spring later, here is a good tutorial. I have tried this, it works:

The blog author Filip is very responsive, you can get clarifications from him if necessary.
