我想保留原始请求的原始有效负载并将其放在 xslt-transformer 或其他操作中。我失去了它，因为我使用了 xslt-transformer，而我只需要转换中的一些元素。所以我的情况是：

1.inbound-gateway（传入 WS 请求）-> 2.xslt-transformer（用于调用外部 WS 的映射）-> 3.outbound-gateway（调用外部 WS）-> 4.xslt-transformer（从分别是外部 WS 和原始请求）

在第 4 步，我没有原始请求，但我需要它，因为我必须将其值放入响应中。我怎么能实现它？

谢谢，V。

由于您的原始消息只是文本，您可以将其复制到标题字段。只要您在存储和检索它之间没有做任何特殊的事情，这应该可以工作。

所以我会尝试的是：

<int:header-enricher input-channel="authenticated-channel" output-channel="pre-routing-channel">
   <int:header name="original-payload" expression="payload.toString()" />
</int:header-enricher>

<!-- changed input channel of router -->
<int-xml:xpath-router id="servicetype-router" input-channel="pre-routing-channel" evaluate-as-string="true">

如果这对您不起作用（可能是因为您必须在两者之间做一些更特别的事情或者有效负载太大），您仍然可以选择使用ClaimCheck。这实际上正是您所要求的。为此，您需要一个MessageStore，然后在修改之前存储消息有效负载。因此，您将调用而不是 header-enricher

<int:claim-check-in input-channel="authenticated-channel" output-channel="pre-routing-channel" message-store="payloadstore" />

<!-- MessageStore definition storing payload using in memory map -->
<bean id="simpleMessageStore"
    class="org.springframework.integration.store.SimpleMessageStore"/>
