public class NoSessionCreationFilter extends PathMatchingFilter
PathMatchingFilter that will disable creating new Sessions during the request. This is a useful
filter to place in the front of any filter chains that may result in REST, SOAP or other service invocations that
are not intended to participate in a session.
This filter enables the following behavior:
Subject does not yet have a Session by the time this filter is called, this filter effectively
disables all calls to subject.getSession() and
subject.getSession(true). If either are called
during the request, an exception will be thrown.Subject already has an associated session before this filter is invoked, either because it
was created in another part of the application, or a filter higher in the chain created one, this filter has no
effect.
subject.getSession(false) (i.e. a false boolean value) will be unaffected
and may be called without repercussion in all cases.appliedPaths, pathMatcherALREADY_FILTERED_SUFFIXfilterConfig| Constructor and Description |
