方法详细资料

• beforeDelivery

  public void beforeDelivery​(@Nullable
                             Method method)
                      throws ResourceException

  This beforeDelivery implementation starts a transaction, if necessary, and exposes the endpoint ClassLoader as current thread context ClassLoader.

  Note that the JCA 1.7 specification does not require a ResourceAdapter to call this method before invoking the concrete endpoint. If this method has not been called (check hasBeforeDeliveryBeenCalled()), the concrete endpoint method should call beforeDelivery and its sibling afterDelivery() explicitly, as part of its own processing.

  指定者:

  beforeDelivery 在接口中 MessageEndpoint

  抛出:

  ResourceException

• getEndpointClassLoader

  protected abstract ClassLoader getEndpointClassLoader()

  Template method for exposing the endpoint's ClassLoader (typically the ClassLoader that the message listener class has been loaded with).

  返回:

  the endpoint ClassLoader (never null)

• hasBeforeDeliveryBeenCalled

  protected final boolean hasBeforeDeliveryBeenCalled()

  Return whether the beforeDelivery(java.lang.reflect.Method) method of this endpoint has already been called.

• onEndpointException

  protected void onEndpointException​(Throwable ex)

  Callback method for notifying the endpoint base class that the concrete endpoint invocation led to an exception.

  To be invoked by subclasses in case of the concrete endpoint throwing an exception.

  参数:

  ex - the exception thrown from the concrete endpoint

• afterDelivery

  public void afterDelivery()
                     throws ResourceException

  This afterDelivery implementation resets the thread context ClassLoader and completes the transaction, if any.

  Note that the JCA 1.7 specification does not require a ResourceAdapter to call this method after invoking the concrete endpoint. See the explanation in beforeDelivery(java.lang.reflect.Method)'s javadoc.

  指定者:

  抛出:

  ResourceException
