以下是一个解决方法的代码示例：

import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;
import com.ibm.mq.MQQueueManager;

public class QueueManagerExample {

    private static final String QUEUE_MANAGER_NAME = "QMGR";
    private static final String CHANNEL_NAME = "CHANNEL";
    private static final String HOST_NAME = "localhost";
    private static final int PORT = 1414;

    public static void main(String[] args) {
        MQEnvironment.hostname = HOST_NAME;
        MQEnvironment.port = PORT;
        MQEnvironment.channel = CHANNEL_NAME;

        try {
            MQQueueManager queueManager = new MQQueueManager(QUEUE_MANAGER_NAME);
            System.out.println("Connected to Queue Manager: " + QUEUE_MANAGER_NAME);

            // Use the queue manager here...

            queueManager.disconnect();
            System.out.println("Disconnected from Queue Manager: " + QUEUE_MANAGER_NAME);
        } catch (MQException e) {
            System.err.println("Failed to connect to Queue Manager: " + e.getMessage());
            e.printStackTrace();
        }
    }
}

请注意，上述代码仅用于演示目的。您需要根据实际情况修改主机名、通道名称和队列管理器名称等参数。另外，您需要确保您的项目中包含了所需的MQ相关的jar文件。
