Question

目前我正在使用mule，需要在WMQ Queue中编写。但是我不想使用WMQ端点，而是希望使用JMS Endpoint来实现。这是我的配置：

我已成功使用JMS端点从WMQ Queue读取消息。但是，当我尝试使用JMS Endpoint在WMQ Queue中编写一些消息时，我的服务器出现以下错误：

2014-07-22 10：11：27,064 [Axis2 Task] ERROR WMQMsg - 预期的MQ 消息格式'MQSTR'，但收到'MQHRF2'2014-07-22 10：11：27,064 [Axis2 Task] WARN QMgrConnection - 将msg移动到死区 1次尝试/尝试后的字母队列： 414D51206C6F63616C6D616E616765721A0CCE5320003C0 2 [致命错误]：1：1：内容是prolog中的nichtzulõssig。错误：'内容非常重要 zologõssiginProlog。' 2014-07-22 10：11：27,064 [Axis2任务] WARN ESBMsg - 错误美化ESBMsg以进行日志打印

我知道发生此错误是因为我尝试写入非JMS队列。另外我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（似乎WMQ也将该属性识别为URL）。

然后，根据我的研究，我发现我无法在网址中直接设置“？targetClient”。而不是那样，我需要创建一个Java类来设置“？targetClient”。要创建这些类，请按照以下URL中的说明进行操作

Create Custom JMSSupport Class

但不幸的是，它对我来说也不起作用。任何人都知道如何解决它？感谢。

注意：在Apache Camel中，我可以通过添加：

来解决它

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

Mule ESB中有类似内容吗？

刚刚解决了问题：

我们需要创建一个java类来设置targetClient是正确的。为此，我们可以按照上面给出的链接。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，我们需要设置一个名为＆＃34; JMS_IBM_Character_Set＆＃34;的属性。（如果不是，我们将在向JMS端点发送请求之前获得＆＃34;预期的MQ消息characterSet＆＃39;＆＃39;，但是收到＆＃39; 1208＆＃39;＆＃34;错误）。以下是我配置它的方法：

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

仅为了您的信息，通过将WMQ端点更改为JMS端点，确保它可以提高性能。

希望它有用：D
