Answer 1

{
//前面是准备管理器和队列
MQQueueManager qMgr = new MQQueueManager(qManager);
int openOptions = MQConstants.MQOO_INPUT_AS_Q_DEF | MQConstants.MQOO_OUTPUT | MQConstants.MQOO_INQUIRE;
MQQueue queue = qMgr.accessQueue(qName, openOptions);
MQMessage rcvMessage = new MQMessage();
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options = gmo.options + MQConstants.MQGMO_WAIT + MQConstants.MQGMO_SYNCPOINT;
//读取五秒超时，这里目的是要有个读取阻塞，和Socket编程类似。
gmo.waitInterval = 5000;
queue.get(rcvMessage, gmo);
//后面就是操作消息的部分【略】
}catch(Exception e){{
