红帽全球峰会383.3. unmarshal
在本例中，我们从名为 MY_QUEUE 的 ActiveMQ 队列到其原始格式，并将它转发到 UnZippedMessageProcessor，并将它转发到 UnZippedMessageProcessor。请注意，在 marshalling 期间使用的压缩级别应该与在 unmarshalling 期间使用的相同，以避免错误。
from("activemq:queue:MY_QUEUE").unmarshal().zip().process(new UnZippedMessageProcessor());
from("activemq:queue:MY_QUEUE").unmarshal().zip().process(new UnZippedMessageProcessor());
