Spring integration int http:inbound gateway consumes="；“应用程序/xml”；和xpathsplitter无法分割消息负载

如果你已经在StackTrace部分编辑了你的文章，那就太好了。它不可读

然而，我最终看到：

原因：org.springframework.messaging.MessaginException:不支持的负载类型[[B]

因此，在

和

之间需要什么呢
<int-http:inbound-gateway id="omega"
    request-channel="requestChannel" error-channel="errorChannel"
    path="/api/mapList" reply-channel="channel9"
    supported-methods="POST">
        <int-http:request-mapping consumes="application/xml"/>
</int-http:inbound-gateway>

<si-xml:xpath-splitter input-channel="requestChannel"
    output-channel="splitterChannel" id="xpathSplitter">
    <si-xml:xpath-expression id="xpathExpression"
        expression="//mapRequests/mapRequest" />
</si-xml:xpath-splitter>
