Class SaveContextOnUpdateOrErrorResponseWrapper

java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

org.springframework.security.web.util.OnCommittedResponseWrapper

org.springframework.security.web.context.SaveContextOnUpdateOrErrorResponseWrapper

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public abstract class SaveContextOnUpdateOrErrorResponseWrapper
extends OnCommittedResponseWrapper

Base class for response wrappers which encapsulate the logic for storing a security context and which store the SecurityContext when a sendError(), sendRedirect, getOutputStream().close(), getOutputStream().flush(), getWriter().close(), or getWriter().flush() happens on the same thread that this SaveContextOnUpdateOrErrorResponseWrapper was created. See issue SEC-398 and SEC-2005.

Sub-classes should implement the saveContext(SecurityContext context) method.

Support is also provided for disabling URL rewriting

Since:

3.0

Constructor Detail

SaveContextOnUpdateOrErrorResponseWrapper

public SaveContextOnUpdateOrErrorResponseWrapper(javax.servlet.http.HttpServletResponse response,
                                                 boolean disableUrlRewriting)

Parameters:

response - the response to be wrapped

disableUrlRewriting - turns the URL encoding methods into null operations, preventing the use of URL rewriting to add the session identifier as a URL parameter.

Method Detail

disableSaveOnResponseCommitted

public void disableSaveOnResponseCommitted()

Invoke this method to disable automatic saving of the SecurityContext when the HttpServletResponse is committed. This can be useful in the event that Async Web Requests are made which may no longer contain the SecurityContext on it.

saveContext

protected abstract void saveContext(SecurityContext context)

Implements the logic for storing the security context.

Parameters:

context - the SecurityContext instance to store

onResponseCommitted

protected void onResponseCommitted()

Calls saveContext() with the current contents of the SecurityContextHolder as long as () was not invoked.

Specified by:

onResponseCommitted in class OnCommittedResponseWrapper

Specified by:

encodeRedirectUrl in interface javax.servlet.http.HttpServletResponse

Overrides:

isContextSaved

public final boolean isContextSaved()

Tells if the response wrapper has called saveContext() because of this wrapper.
