已经被这个问题困扰了几个小时了，有人有什么想法吗？

java.lang.NoSuchMethodError: com.ibm.mq.MQException.(Ljava/lang/String;Ljava/lang/String;II)V 在 com.ibm.msg.client.wmq.common.internal.Reason.createException(Reason.java:223) 在 com.ibm.msg.client.wmq.internal.WMQMessageConsumer.checkJmqiCallSuccess(WMQMessageConsumer.java:123) 在 com.ibm.msg.client.wmq.internal.WMQConsumerShadow.getMsg(WMQConsumerShadow.java:1198) 在 com.ibm.msg.client.wmq.internal.WMQSyncConsumerShadow.receiveInternal（WMQSyncConsumerShadow.java:233）在 com.ibm.msg.client.wmq.internal.WMQConsumerShadow.receive（WMQConsumerShadow.java:922）在 com.ibm.msg.client.wmq.internal.WMQMessageConsumer.receive(WMQMessageConsumer.java:450) 在 com.ibm.msg.client.jms.internal.JmsMessageConsumerImpl.receiveInboundMessage（JmsMessageConsumerImpl.java:742）在 com.ibm.msg.client.jms.internal.JmsMessageConsumerImpl.receive(JmsMessageConsumerImpl.java:423) 在 com.ibm.mq.jms.MQMessageConsumer.receive(MQMessageConsumer.java:258)

当我使用 MQ 本机库放置消息并使用 JMS API 读取它们时，出现此错误。 jms 读取失败，抛出上述异常。我也在使用 jms Selector，这似乎是导致问题的原因。没有选择器一切正常。 TIA。

最后我能够解决这个问题，这一切都与选择器的创建方式有关。不同之处在于 MQ API 将相关 ID 作为字节数组，而 JMS 将其作为字符串。因此，选择器无法选择消息并抛出已发布的错误。该错误根本不适合调试，因此必须进行大量的试验和错误。不管怎样，现在这有效了，所以我很高兴。下面是我为此必须做的代码更改：

//字符串选择器 = "JMSCorrelationID = '" + corleationID + "'";更改前

        StringBuffer fBuf = new StringBuffer("JMSCorrelationID = 'ID:");
        byte[] correlBytes = corleationID.getBytes();
        for(int i=0; i<24; i++) {
          if (i>=correlBytes.length) {
            fBuf.append("00");
          } else {
            byte b = correlBytes[i];
            String hexStr = Integer.toHexString(b);
            // -ve values produce 8 char results
            if (hexStr.length()>2) hexStr = hexStr.substring(hexStr.length()-2);
            // small values produce 1 char results
            if (hexStr.length()<2) fBuf.append("0");
            fBuf.append(hexStr);
          }
        }
        fBuf.append("'");
        String filter = fBuf.toString();
        System.out.println("creating receiver with filter: "+filter);
        QueueReceiver queueReceiver = queueSession.createReceiver(inQueue,filter);

// QueueReceiverqueueReceiver =queueSession.createReceiver(inQueue, 选择器);

参考了IBM文档中的代码。

Finally i was able to resolve this, it all had to do with how the selector is created. The difference was that MQ API's have correlation id as bytes array where as JMS takes it as a string. Due to this the Selector was unable to select the message and was throwing the posted error. The error is not at all debug friendly hence had to do a lot of trial and error. Anyways now this works so i am glad. Below is the code change i had to do for this:

//String selector = "JMSCorrelationID = '" + corleationID + "'"; before change

        StringBuffer fBuf = new StringBuffer("JMSCorrelationID = 'ID:");
        byte[] correlBytes = corleationID.getBytes();
        for(int i=0; i<24; i++) {
          if (i>=correlBytes.length) {
            fBuf.append("00");
          } else {
            byte b = correlBytes[i];
            String hexStr = Integer.toHexString(b);
            // -ve values produce 8 char results
            if (hexStr.length()>2) hexStr = hexStr.substring(hexStr.length()-2);
            // small values produce 1 char results
            if (hexStr.length()<2) fBuf.append("0");
            fBuf.append(hexStr);
          }
        }
        fBuf.append("'");
        String filter = fBuf.toString();
        System.out.println("creating receiver with filter: "+filter);
        QueueReceiver queueReceiver = queueSession.createReceiver(inQueue,filter);
