org.springframework.jms.listener.serversession
Class SimpleServerSessionFactory

java.lang.Object
  org.springframework.jms.listener.serversession.SimpleServerSessionFactory

All Implemented Interfaces:: ServerSessionFactory

public class SimpleServerSessionFactory
extends Object
implements ServerSessionFactory
extends Object
implements ServerSessionFactory

The simplest possible implementation of the ServerSessionFactory SPI: creating a new ServerSession with a new JMS Session every time. This is the default used by ServerSessionMessageListenerContainer.

The execution of a ServerSession (and its MessageListener) gets delegated to a TaskExecutor. By default, a SimpleAsyncTaskExecutor will be used, creating a new Thread for every execution attempt. Alternatives are a TimerTaskExecutor, sharing a single Thread for the execution of all ServerSessions, or a TaskExecutor implementation backed by a thread pool.

To reuse JMS Sessions and/or to limit the number of concurrent ServerSession executions, consider using a pooling ServerSessionFactory: for example, CommonsPoolServerSessionFactory.

Field Summary

static String DEFAULT_THREAD_NAME_PREFIX
          Default thread name prefix: "SimpleServerSessionFactory-".

Constructor Summary

SimpleServerSessionFactory()


Method Summary

void close(ListenerSessionManager sessionManager)
          This implementation is empty, as there is no state held for each ListenerSessionManager.

ServerSession getServerSession(ListenerSessionManager sessionManager)
          Creates a new SimpleServerSession with a new JMS Session for every call.

protected TaskExecutor getTaskExecutor()
          Return the TaskExecutor to use for executing ServerSessions.

void setTaskExecutor(TaskExecutor taskExecutor)
          Specify the TaskExecutor to use for executing ServerSessions (and consequently, the underlying MessageListener).
