jms - 骡子 ESB : Setup JMS Endpoint for WMQ Queue

Question

目前我正在使用骡子，需要在 WMQ 队列中写入。但是我不想使用 WMQ 端点，而是想通过使用 JMS 端点来实现。这是我的配置:

我已使用 JMS 端点成功从 WMQ 队列读取消息。但是，当我尝试使用 JMS 端点在 WMQ 队列中写入一些消息时，我的服务器出现以下错误:

2014-07-22 10:11:27,064 [Axis2 Task] ERROR WMQMsg - Expected MQ message format ' MQSTR ', but received 'MQHRF2 ' 2014-07-22 10:11:27,064 [Axis2 Task] WARN QMgrConnection - Moving msg into dead letter queue after 1 try/tries: 414D51206C6F63616C6D616E616765721A0CCE5320003C0 2 [Fatal Error] :1:1: Content ist nicht zulõssig in Prolog. ERROR: 'Content ist nicht zulõssig in Prolog.' 2014-07-22 10:11:27,064 [Axis2 Task] WARN ESBMsg - Error prettifying ESBMsg for log printing

我知道发生此错误是因为我尝试写入非 JMS 队列。我也知道我必须通过设置“?targetClient=1”来解决它。但是，当我尝试将 targetClient 属性添加到我的队列 URL 中时，我仍然收到错误消息(似乎该属性也被 WMQ 识别为 URL)。

然后，通过我的研究，我发现我不能直接在 url 中设置“？targetClient”。取而代之的是，我需要创建一个 Java 类来设置“？targetClient”。要创建这些类，我按照以下 URL 中的一些说明进行操作

Create Custom JMSSupport Class

但不幸的是，它也对我不起作用。任何人都知道我该如何解决它？谢谢。

注意:在 Apache Camel 中，我可以通过添加以下内容来简单地解决它:

<setHeader headerName="CamelJmsDestinationName">
    <constant>queue:///LSMH.ZKSEAP.SERVICEBUS?targetClient=1</constant>    
</setHeader>

Mule ESB中是否有类似的东西？

刚刚解决了这个问题:

没错，我们需要创建一个java类来设置targetClient。为此，我们可以按照我上面提供的链接进行操作。但是，我们需要稍微更改一下代码。
这是正确的代码:

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Session;

import org.mule.api.endpoint.ImmutableEndpoint;
import org.mule.transport.jms.Jms11Support;
import org.mule.transport.jms.JmsConnector;

import com.ibm.mq.jms.JMSC;
import com.ibm.mq.jms.MQQueue;

/**
* Implements WebSphere MQ specific JMS support for Mule. The class
* overrides the createDestination method to intercept JMS Queue object
* creation and sets the targetClient=1 property on created MQQueue
* objects. This is necessary to prevent non-JMS consumers from being
* choked by RFH2 headers.
*/
public class CustomJms11Support extends Jms11Support {

    public CustomJms11Support(JmsConnector connector) {
        super(connector);
    }

    @Override
    public Destination createDestination(Session session, String name, boolean
    topic, ImmutableEndpoint ie) throws JMSException {
        Destination destination = super.createDestination(session, name, topic, ie);
        if (destination instanceof MQQueue){
            ((MQQueue) destination).setTargetClient(JMSC.MQJMS_CLIENT_NONJMS_MQ);
        }
        return destination;
    }
}

然后，在将请求发送到 JMS 端点之前，我们需要设置一个名为“JMS_IBM_Character_Set”的属性(如果没有，我们将收到“Expected MQ message characterSet '819', but received '1208'”错误)。这是我如何配置它:

<set-property propertyName="JMS_IBM_Character_Set" value="ISO8859_1" doc:name="Property"/>

仅供引用，通过将 WMQ 端点更改为 JMS 端点，可以确保提高性能。

希望它会有用:D
