Hi,
I've created a GAE web application using Spring 3.0 and Spring
Security 2.0.5.
After a little heartache and help from reading the posts on the forum,
I managed to get it all working locally, with users able to register,
validate their accounts via email and login in securely.
When a user logs in, I wanted to make their details available across
the site. I did this by creating an Interceptor, responsible for
pulling the prinicipal from the Spring Security Authentication class
(retrieved from the SecurityContextHolder) and then placing the object
in the HttpServletRequest object. Below is a snippet of code from the
interceptor.
public void postHandle(
HttpServletRequest request,
HttpServletResponse response,
Object handler,
ModelAndView modelAndView) {
try {
Member member = securityContext.getMember();
request.setAttribute("user", member);
log.info("injecting user into request");
} catch(SecurityRuntimeException e) {
// do nothing - will be thrown if no user is logged in
}
}
The user's information is wrapped in a 'Member' object, with the
securityContext responsible for retrieving it from the
SecurityContextHolder.
Locally, on the GAE development environment, everything works fine!
The interceptor correctly places the principal in the request and my
JSP's can readily access it. However, when I deploy the application to
the app engine, it does not appear to work. The logs have not provided
any clue as to why the request does not appear to have the principal
in it.
Is there any reason why the interceptor would not work on the app
engine? Or, is it ill-advised to add objects into the
HttpServletRequest?
I'm tearing my hair out with why it's not working, and it's the only
thing within my application that isn't! So any help or advice offered
is much appreciated. I'm hoping to have my code up in the Google Code
repository so if anyone wants to have a look, they're more than
welcome.
Thanks!
Sully
