public class OpenPersistenceManagerInViewFilter extends OncePerRequestFilter
This filter makes JDO PersistenceManagers available via the current thread,
which will be autodetected by transaction managers. It is suitable for service
layer transactions via JdoTransactionManager
or JtaTransactionManager as well
as for non-transactional read-only execution.
Looks up the PersistenceManagerFactory in Spring's root web application context.
Supports a "persistenceManagerFactoryBeanName" filter init-param in web.xml;
the default bean name is "persistenceManagerFactory".

doFilterInternal(HttpServletRequest request,

FilterChain filterChain)
Same contract as for
doFilter, but guaranteed to be
just invoked once per request within a single request thread. |
protected java.lang.String |
getPersistenceManagerFactoryBeanName()
Return the bean name of the PersistenceManagerFactory to fetch from Spring's
root application context.
|
protected javax.jdo.PersistenceManagerFactory |
lookupPersistenceManagerFactory()
Look up the PersistenceManagerFactory that this filter should use.
|
protected javax.jdo.PersistenceManagerFactory |
lookupPersistenceManagerFactory(HttpServletRequest request)
Look up the PersistenceManagerFactory that this filter should use,
taking the current HTTP request as argument.
|
void |
setPersistenceManagerFactoryBeanName(java.lang.String persistenceManagerFactoryBeanName)
Set the bean name of the PersistenceManagerFactory to fetch from Spring's
root application context.
|
protected boolean |
shouldNotFilterAsyncDispatch()
Returns "false" so that the filter may re-bind the opened
PersistenceManager
to each asynchronously dispatched thread and postpone closing it until the very
last asynchronous dispatch. |
protected boolean |
shouldNotFilterErrorDispatch()
Returns "false" so that the filter may provide an
PersistenceManager
to each error dispatches. |
