Spring integration 在网关中设置标头值

下面是我目前为我们的web服务所做的配置。对于每个服务，我创建一个单独的网关和报头enricher，这样我就可以添加一个报头，告诉路由器要路由到哪个服务。为了简洁起见，我省略了一些配置。我也明白，这可以通过另一个流来完成-但是还有一些其他工作部分（如版本控制、弃用等），所以我需要以这种方式进行设置，并在流中稍后使用自定义路由器

                <prop key="${service.endpoint.url}/SNTWS/service/ContactService">SOAPContactGateway</prop>

            </props>
        </property>

        service type. -->

我需要一个单独的网关和头enricher的原因是，我可以在消息上设置适当的服务头。所有消息都将放在SOAPRequestChannel上，在那里我可以获得版本

理想情况下，为了减少配置，我希望所有端点映射都有一个网关。我可以从URL设置标题，因为我知道最后一部分是服务名称

---

我正在寻找这样做的想法。我可以使用Spel访问URL路径吗

是的，您可以使用

URI

：

<int:header-enricher>
    <int:header name="uri" 
      expression="T(org.springframework.ws.transport.context.TransportContextHolder).transportContext.connection.uri" />
</int:header-enricher>

这样，您就可以基于该

uri

值进行路由，甚至可以分别摆脱这两个

和

值
