Is the method
public void messageReceived(final IoSession session, final Object
message) throws Exception {
threadsafe per IoSession?
That is can the same IoSession under any circumstance receive messages
at the same time?
If it is threadsafe, then i am curious if this should work for accessing
EM in a threadsafe way?
And if it is assured to close? And/or under what circumstances
sessionDestroyed might not be called?
ie OutOfMemoryError, etc
public void sessionCreated(final IoSession session) throws Exception {
session.setAttribute("EM",
entityManagerFactory.createEntityManager());
public void sessionDestroyed(final IoSession session) throws Exception {
final EntityManager entityManager = (EntityManager)
session.getAttribute("EM");
entityManager.close();
public void messageReceived(final IoSession session, final Object
message) throws Exception {
final EntityManager entityManager = (EntityManager)
session.getAttribute("EM");
// do something with EM
I am also wondering, bar Spring, etc, thoughts on whether this would be
considered a good practice?
Assuming the above plays out.
Thanks,
Jason
