我们可以将我的Java-Spring-mvc服务连接到IBM MQ而不用从队列中生成或使用绑定文件吗？

Question

in my service(built on java8 - springMVC - IBM MQ) we are generating binding file from IBM MQ and and using that binding file to connect to queues and my service. is there any way i could connect with the queue without using that binding file.

The reason is my service is talking with 10 queues and for every queue i have to generate binding file and put them all in one file and use it and we have dev, qa, prod environments so binding files change for each of them and this is big pain.

so is there a way to connect queues without the binding files and possible please attach the code or any reference!

You can use below code with IBM MQ jars.




import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;
import com.ibm.mq.MQGetMessageOptions;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;

public class Test {

    public static void main(String[] args) {
            MQEnvironment.hostname = queue_manager_ip;
            MQEnvironment.port = queue_manager_port;
            MQEnvironment.channel = channel_name;
            MQEnvironment.disableTracing();

            MQQueueManager mqmanager = null;
            MQQueue mqueue = null;

            try {
                mqmanager = new MQQueueManager(" ");
                int i = 8226;

                mqueue = mqmanager.accessQueue(queue_name, i);
            } catch (MQException localMQException) {
                System.out.println(localMQException.getMessage());
            }
            String str1 = "";
            String str2 = "";

            MQGetMessageOptions localMQGetMessageOptions = new MQGetMessageOptions();
            localMQGetMessageOptions.options = 8192;

            MQMessage localMQMessage = new MQMessage();
            mqueue.get(localMQMessage, localMQGetMessageOptions);
            byte[] arrayOfByte = new byte[localMQMessage.getTotalMessageLength()];
            localMQMessage.readFully(arrayOfByte);
            str1 = new String(arrayOfByte);
            System.out.println(str1);
    }

}
