批量把XML文件投入MQ，和批量把MQ生成XML文件的java工具

      项目中有大量的MQ接口，尤其是进入结合测试以后，有大量的MQ的投入和取出需求。用Webshpere的MQ资源管理器实现太慢，而且手动作业太多了。手动写了两个工具，一个是VBA对固定格式的接口文件，生成MQ接口测试用的XML文件。一个是java写的，针对MQ的批量XML投入和取出生成XML文件的工具。这里介绍第二个，第一个VBA工具有需要的可以留言。

      思路：因为只是单纯文件读写，不涉及到XML解析，使用apache的 commons.io进行文件读取和写入；MQ的读写使用javax.jms和ibm.mq.allclient。所以除了jdk1.8的库以外，还需要三个jar包。 com.ibm.mq.allclient.jar，commons-io-2.6.jar，javax.jms-api-2.0.1.jar。

      代码实现：MQCommon.java

public static ResourceBundle createResourceBundle() {
		// JMS setting file (mq.properties)
		ResourceBundle bundle = ResourceBundle.getBundle(JMS_PROPERTIES);
		return bundle;
	}

	public static MQQueueConnectionFactory createMQQueueConnectionFactory(ResourceBundle bundle) throws JMSException {
		// Configure QueueConnectionFactory.
		MQQueueConnectionFactory factory = new MQQueueConnectionFactory();
		factory.setTransportType(com.ibm.mq.jms.JMSC.MQJMS_TP_CLIENT_MQ_TCPIP);
		factory.setHostName(bundle.getString(JMS_HOST));
		factory.setPort(Integer.valueOf(bundle.getString(JMS_PORT)));
		factory.setChannel(bundle.getString(JMS_CHANNEL));
		return factory;
	}

	public static QueueConnection createQueueConnection(MQQueueConnectionFactory factory) throws JMSException {
		String password = System.getProperty(MQ_Password_KEY, "");
		String userId = System.getProperty(MQ_UserID_KEY, MQ_UserID);
		System.out.println("user[" + userId + "],password[" + password + "] for connection");

		QueueConnection conn = factory.createQueueConnection(userId, password);
		return conn;
	}

	public static QueueSession createQueueSession(QueueConnection conn) throws JMSException {
		QueueSession session = conn.createQueueSession(true, QueueSession.AUTO_ACKNOWLEDGE);
		return session;
	}

	public static MQQueue createMQQueue( String queueName) throws JMSException {

	}

遇到的坑：

1，用commons.io读取和写入utf8编码问题，都需要特殊指定，否则会按照默认编码去读。

//读utf8文件
inFile = new FileInputStream(file);
String message = IOUtils.toString(inFile,"utf-8");
//写utf8文件
BufferedWriter fileWriter = new BufferedWriter(new OutputStreamWriter (new FileOutputStream(filePath,true),"utf-8"));
fileWriter.write(message);

2，MQ的取出的话，commit也要明确的写，不然读完之后会依然存在。
