本文介绍了如何使用Java连接到IBM MQ的Topic，包括在MQ上定义Topic的步骤以及Java代码示例，展示了发送和接收消息的过程。

1：java 连接ibm mq的topic首先需要在mq上建立topic,命令如下
     DEFINE TOPIC(TOPIC_xx_2) TOPICSTR(NBA/LAKER) DESCR('This is a TOPIC') PUB(ASPARENT) SUB(ENABLED) WILDCARD(PASSTHRU)
至于队列管理器的创建见日志中的MQ队列管理建立日志
2：java连接程序

import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQGetMessageOptions;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQPutMessageOptions;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.MQTopic;
import com.ibm.mq.pcf.CMQC;
