Question

我在Mule中有一个要求，我需要在其中公开SOAP Web服务。现在我在2个流程中实现它： -

<flow name="ServiceFlow" doc:name="ServiceFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP" />
<cxf:jaxws-service serviceClass="com.test.services.schema.maindata.v1.MainData" doc:name="SOAP" />
        <object-to-string-transformer doc:name="Object to String"/>
<jms:outbound-endpoint queue="NewQueue" connector-ref="Active_MQ" doc:name="JMS"/>
</flow>


<flow name="Flow2" doc:name="Flow2" >
<jms:inbound-endpoint connector-ref="Active_MQ" address="jms://tcp:NewQueue" doc:name="JMS" exchange-pattern="request-response"/>
<component class="com.test.services.schema.maindata.v1.Impl.MainDataImpl" doc:name="JavaMain_ServiceImpl" >
<method-entry-point-resolver>
        <include-entry-point method="retrieveDataOperation"/>
        <include-entry-point method="insertDataOperation"/>
        <include-entry-point method="updateDataOperation"/>
        <include-entry-point method="deleteDataOperation"/>
</method-entry-point-resolver>
</component>
<logger level="INFO" message="payload :-#[message.payload]" doc:name="Logger"/>
</flow>

在第一个流程（ServiceFlow）中，我尝试在ActiveMQ队列和第二个流程（Flow2）中发送SOAP请求。我正在尝试使用 MainDataImpl 类中的请求。但我在使用请求时遇到异常： -

Exception stack is:
1. "Message with id "ID:ANIRBAN-PC-49419-1407595657591-1:1:6:1:1" has been redelivered 1 times on endpoint "jms://tcp:NewQueue", which exceeds the maxRedelivery setting of 0 on the connector "Active_MQ".

现在我想知道如何解决这个问题，因为我猜 MainDataImpl 期望消息为对象类型..但是没有办法将String消息转换为Object ...任何针对上述问题的解决方案???请帮忙

在添加对象XML后更新：

<jms:activemq-connector name="Active_MQ" brokerURL="tcp://localhost:61616" validateConnections="true" doc:name="Active MQ"/>

<flow name="ServiceFlow" doc:name="ServiceFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP" />
<cxf:jaxws-service serviceClass="com.test.services.schema.maindata.v1.MainData" doc:name="SOAP" />
        <mulexml:object-to-xml-transformer doc:name="Object to XML"/>

<!-- <vm:outbound-endpoint exchange-pattern="request-response" path="Flow1-WT-Main" doc:name="VM"/> -->

   <jms:outbound-endpoint queue="NewQueue" connector-ref="Active_MQ" doc:name="JMS"/>
</flow>


<flow name="Flow2" doc:name="Flow2" >
<!-- <vm:inbound-endpoint exchange-pattern="request-response" path="Flow1-WT-Main" doc:name="VM"/> -->

<jms:inbound-endpoint connector-ref="Active_MQ" address="jms://tcp:NewQueue" doc:name="JMS" exchange-pattern="request-response"/>
        <mulexml:xml-to-object-transformer doc:name="XML to Object"/>
        <async doc:name="Async">
            <logger message="Payload :-#[message.payload]" level="INFO" doc:name="Logger"/>
        </async>
<component class="com.test.services.schema.maindata.v1.Impl.MainDataImpl" doc:name="JavaMain_ServiceImpl" >
<method-entry-point-resolver>
        <include-entry-point method="retrieveDataOperation"/>
        <include-entry-point method="insertDataOperation"/>
        <include-entry-point method="updateDataOperation"/>
        <include-entry-point method="deleteDataOperation"/>
</method-entry-point-resolver>

</component>

<logger level="INFO" message="ccccccc :-#[message.payload]" doc:name="Logger"/>
    </flow>

现在例外是： -

Answer 1

正如您所猜测的那样，问题是您将入站消息对象序列化为具有object-to-string-transformer的String，并通过JMS队列尝试将其提供给MainDataImpl对象，该对象接收对象作为其不同操作的输入参数。

解决方案是简单地将入站对象序列化为XML，通过JMS发送，然后将其反序列化为对象。

为此，将object-to-string-transformer替换为object-to-xml-transformer，并在xml-to-object-transformer之后添加jms:inbound-endpoint。

修改我没有意识到你以NewQueue方式使用request-response，因为你实际上并不一致地声明它。在jms:outbound-endpoint上，您没有提供默认为exchange-pattern的{{1}};在one-way设置jms:inbound-endpoint到exchange-pattern时，会触发执行request-response的响应阶段。

所以：保持一致，在两个JMS端点上使用相同的Flow2，或者更好的是，使用正确的exchange-pattern声明一个全局JMS端点并从中引用它jms：入站和出站端点。

如果您决定留在exchange-pattern，那么您需要对响应做同样的事情，即。将调用request-response（一个MainDataImpl对象）的结果序列化回XML，并在DataResponse中将其反序列化回对象。

Answer 2

因此，工作解决方案是（根据大卫的建议） 1.需要在JMS出站之前添加<mulexml:object-to-xml-transformer doc:name="Object to XML"/>，在JMS入站之后添加<mulexml:xml-to-object-transformer doc:name="XML to Object"/> 2.需要在两个JMS端点上使用相同的exchange-pattern
