java – 如何解决消息有效负载的类型为：BufferInputStream Mule中的异常

我已经转换为字节数组但我不断收到此错误：

ERROR 2015-02-25 11:12:30,517 [[ESR].HTTP_Request_Listener.worker.01] org.mule.exception.DefaultMessagingExceptionStrategy:

    + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

这是我的流程：

<sub-flow name="requestBeanCreate">
    <object-to-byte-array-transformer />
    <set-payload value="#[app.registry.messageBean.createServiceRequest(message.inboundProperties['http.uri.params']['name'],payload)]"/>
</sub-flow>

<flow name = "RequestsEntryFlow" >
    <http:listener allowedMethods="POST"  parseRequest="false"  config-ref="HTTP_Request_Listener" path="/{name}" doc:name="HTTP Entry Flow" />
    <flow-ref name="requestBeanCreate" />
    <choice doc:name="Choice">
        <when expression="#[app.registry.messageBean.isEMCRequired(payload)]">
            <jms:outbound-endpoint connector-ref="jms-connector" ref="EMCRequiredRequestsQueue" />
        </when>
        <otherwise>             
             <flow-ref name="req" />
        </otherwise>
    </choice>
</flow>

<http:request-config parseResponse="false" name="HTTP_Request_Configuration"   />

<sub-flow name = "req">    
    <set-variable variableName="id" value="#[payload]" doc:name="Variable" />
    <set-variable variableName="destination" value="#[app.registry.routerBean.getDestination(app.registry.messageBean.getReceiverID(payload))]"  doc:name="Variable" />
    <set-payload value="#[app.registry.messageBean.sendRequestToDestination(payload)]" />              
    <processor-chain>
    <http:request  parseResponse="false" config-ref="HTTP_Request_Configuration" host="#[flowVars.destination]" port="80" path="/" method="POST" />
        <object-to-byte-array-transformer />
        <expression-component>
            app.registry.messageBean.sendResponseToSender(flowVars.id);
            app.registry.messageBean.messageProcessedSuccessfully(flowVars.id);
        </expression-component>
    </processor-chain>
</sub-flow>

解决方法

<http:request parseResponse="false" config-ref="HTTP_Request_Configuration" host="#[flowVars.destination]" port="80" path="/" method="POST">
        <http:success-status-code-validator values="0..599"/>
    </http:request>
