WebSphere MQ的配置请参考配置IBM WEBSPHERE MQ触发器中的方法二，唯一要改的是定义进程，定义进程改为如下：
DEFINE PROCESS('JAVA.PROCESS') REPLACE +
DESCR('Process to test triggering') +
APPLICID('java -classpath E:/MQTrigger/MQTrigger.jar com.bijian.study.JavaTrigger')
由java -classpath E:/MQTrigger/MQTrigger.jar com.bijian.study.JavaTrigger可知，我将如下工程代码导出为MQTrigger.jar放到了E盘的MQTrigger目录下。
