Question

我通过JMS将以下json消息发送到流：

[{＆＃34; salesOrderId＆＃34;：＆＃34; 00001-2-3＆＃34;，＆＃34; saleName＆＃34;：＆＃34; Car Sale＆＃34;，＆＃34;状态＆＃34;：＆＃34;处理＆＃34;}，{＆＃34; salesOrderId＆＃34;：＆＃34; 00004-5-6＆＃34;，＆＃34; saleName＆＃34;：＆＃34 ;房屋销售＆＃34;，＆＃34;状态＆＃34;：＆＃34;处理＆＃34;}]

这是我的策略：

    <flow name="integration-consumer-client2" doc:name="integration-consumer-client2">
    <jms:inbound-endpoint queue="client2.queue" connector-ref="Active_MQ" doc:name="JMS"/>
    <logger message="Consumes Client 2 = #[payload]" level="INFO" doc:name="Logger"/>
    <logger message="Client 2 Correlation = #[message.correlationId]" level="INFO" doc:name="Logger"/>
    <vm:outbound-endpoint exchange-pattern="one-way" path="response" doc:name="VM"/>
</flow>
<flow name="integration-consumer-client" doc:name="integration-consumer-client">
    <jms:inbound-endpoint doc:name="JMS" connector-ref="Active_MQ" queue="client1.queue">
    </jms:inbound-endpoint>
    <logger message="Consumes Client = #[payload]" level="INFO" doc:name="Logger"/>
    <logger message="Client Correlation = #[message.correlationId]" level="INFO" doc:name="Logger"/>
    <vm:outbound-endpoint exchange-pattern="one-way" path="response" doc:name="VM"/>      
</flow>  
<flow name="integration-flow" doc:name="integration-flow">
    <vm:inbound-endpoint path="response" doc:name="VM">
         <message-properties-transformer>
            <add-message-property key="MULE_CORRELATION_GROUP_SIZE" value="2" />
        </message-properties-transformer>
        <collection-aggregator/>
    </vm:inbound-endpoint>
    <logger message="after vm = #[payload]" level="INFO" doc:name="Logger"/>
     <request-reply doc:name="Request-Reply">
        <jms:outbound-endpoint queue="queue.validation" connector-ref="Active_MQ" doc:name="JMS">
             <jms:object-to-jmsmessage-transformer doc:name="Object to JMSMessage"/>
        </jms:outbound-endpoint>
        <jms:inbound-endpoint queue="queue.validation.response" connector-ref="Active_MQ" doc:name="JMS"/>
    </request-reply>
    <logger message="Siebel Response in ESB = #[payload]" level="INFO" doc:name="Logger"/>
</flow>

因此聚合了两个消费者消息，然后使用JMS通过请求回复将其发送到另一个流。在那个流程中，消息来自as [{＆＃34; salesOrderId＆＃34;：＆＃34; 00001-2-3＆＃34;，＆＃34; saleName＆＃34;：＆＃34; Car Sale＆＃34;，＆＃34; status＆＃34 ;：＆＃34;处理＆＃34;}，{＆＃34; salesOrderId＆＃34;：＆＃34; 00004-5-6＆＃34;，＆＃34; saleName＆＃34;：＆＃34; House Sale＆＃34;＆＃34;状态＆＃34;：＆＃34;处理＆＃34;}]

和流程：

    <jms:activemq-connector name="Active_MQ" username="admin" password="admin" brokerURL="tcp://localhost:61616" validateConnections="true" doc:name="Active MQ"/>
<data-mapper:config name="JSON_To_JSON" transformationGraphPath="json_to_json.grf" doc:name="JSON_To_JSON"/>
<flow name="validation-flow" doc:name="validation-flow">
    <jms:inbound-endpoint doc:name="JMS" connector-ref="Active_MQ" queue="queue.validation" >
        <jms:jmsmessage-to-object-transformer doc:name="JMSMessage to Object"/>    
    </jms:inbound-endpoint>

    <logger message="Payload = #[payload]" level="INFO" doc:name="Logger"/>
    <data-mapper:transform config-ref="JSON_To_JSON" doc:name="JSON To JSON"/>
    <logger message="inside siebel after mapper = #[payload]" level="INFO" doc:name="Logger"/>
</flow>

我想通过mapper发送数据，因为我想将状态更改为＆＃34; Complete＆＃34;。但是在json到json mapper之后，结果是[B @ 2b9f82b。如何将jms消息转换为对映射器更具可读性？

你拥有的是一个完全有效的bytearray。您可以使用对象到字符串转换器再次将其转换为String，或者甚至更好地将字节数组转换为字符串转换器。
