handleMessage

public void handleMessage(Message<?> message)

Description copied from interface: MessageHandler

Handles the message if possible. If the handler cannot deal with the message this will result in a MessageRejectedException e.g. in case of a Selective Consumer. When a consumer tries to handle a message, but fails to do so, a MessageHandlingException is thrown. In the last case it is recommended to treat the message as tainted and go into an error scenario.

When the handling results in a failure of another message being sent (e.g. a "reply" message), that failure will trigger a MessageDeliveryException.

Specified by:

handleMessage in interface MessageHandler

Parameters:

message - the message to be handled
