测试代码：

import java.io.File;

public class BlobMessageTest {

	/**
	 * topic方式，必须先启动消费者，然后是生产者，否则接收不到消息。 queue方式，最好先启动生产者，然后启动消费者，否则也容易收不到消息。
	 * 
	 * @param args
	 */
	public static void main(String[] args) throws Exception {

		BlobMessageSendTest producer = new BlobMessageSendTest();
		BlobMessageReceiveTest consumer = new BlobMessageReceiveTest();

		String fileName = "D:/装Win7后装XP.txt";
		// String fileName = "d:/JAVA+开发视频会议系统详细设计.doc";
		File file = new File(fileName);
		producer.produceMessage(file);

		producer.close();
		// 延时500毫秒之后停止接受消息
		Thread.sleep(2000);
		// 开始监听
		consumer.consumeMessage();
		// 延时500毫秒之后发送消息
		Thread.sleep(2000);
		consumer.close();
