Method Detail

containsContext

public boolean containsContext(javax.servlet.http.HttpServletRequest request)

Description copied from interface: SecurityContextRepository

Allows the repository to be queried as to whether it contains a security context for the current request.

Specified by:

containsContext in interface SecurityContextRepository

Parameters:

request - the current request

Returns:

true if a context is found for the request, false otherwise

loadContext

public SecurityContext loadContext(HttpRequestResponseHolder requestResponseHolder)

Description copied from interface: SecurityContextRepository

Obtains the security context for the supplied request. For an unauthenticated user, an empty context implementation should be returned. This method should not return null.

The use of the HttpRequestResponseHolder parameter allows implementations to return wrapped versions of the request or response (or both), allowing them to access implementation-specific state for the request. The values obtained from the holder will be passed on to the filter chain and also to the saveContext method when it is finally called. Implementations may wish to return a subclass of SaveContextOnUpdateOrErrorResponseWrapper as the response object, which guarantees that the context is persisted when an error or redirect occurs.

Specified by:

loadContext in interface SecurityContextRepository

Parameters:

requestResponseHolder - holder for the current request and response for which the context should be loaded.

Returns:

The security context which should be used for the current request, never null.

saveContext

public void saveContext(SecurityContext context,
                        javax.servlet.http.HttpServletRequest request,
                        javax.servlet.http.HttpServletResponse response)

Description copied from interface: SecurityContextRepository

Stores the security context on completion of a request.

Specified by:

saveContext in interface SecurityContextRepository

Parameters:

context - the non-null context which was obtained from the holder.
