java - 检查 MQ 队列深度

Question

谁能帮忙用 java 编写获取队列深度的代码。我们在 IBM WebSphere MQ 中有 4 个队列，其中有消息。

我想编写一个 jsp 来在运行报告时读取队列名称及其深度。 我该怎么做？

参见 http://blog.guymahieu.com/2008/06/11/getting-the-depth-of-an-mqseries-queue-from-java/ .

我重新实现如下:

import com.ibm.mq.*;

public class QueueManager {

    private final String host;
    private final int port;
    private final String channel;
    private final String manager;
    private final MQQueueManager qmgr;

    public QueueManager(String host, int port, String channel, String manager) throws MQException {
        this.host = host;
        this.port = port;
        this.channel = channel;
        this.manager = manager;
        this.qmgr = createQueueManager();
    }

    public int depthOf(String queueName) throws MQException {
        MQQueue queue = qmgr.accessQueue(queueName, MQC.MQOO_INQUIRE | MQC.MQOO_INPUT_AS_Q_DEF, null, null, null);
        return queue.getCurrentDepth();
    }

    @SuppressWarnings("unchecked")
    private MQQueueManager createQueueManager() throws MQException {
        MQEnvironment.channel = channel;
        MQEnvironment.port = port;
        MQEnvironment.hostname = host;
        MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
        return new MQQueueManager(manager);
    }
}

将以下 jar 放在你的类路径中:

• com.ibm.mq*jar
• j2ee.jar
