I want to use spring integration to replace my old webservice gateway. in old gateway, program receive the request and send out by httpclient.
here is my old webservice gateway's send part

 DefaultHttpClient httpClient = null;

    Map<String,String> map = new HashMap<String,String>();

    httpClient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost(dynamicUrl);

    String soapRequestData =dynamicXMLString;

    HttpEntity re = new StringEntity(soapRequestData, HTTP.UTF_8);

    httppost.setHeader("Content-Type","application/soap+xml; charset=utf-8");

    httppost.setEntity(re);

    try {

        HttpResponse response = httpClient.execute(httppost);

        if(response.getStatusLine().getStatusCode() == 200) {  

            String xmlString = EntityUtils.toString(response.getEntity());

            System.out.println("-------------------------");

            System.out.println(xmlString);

        }

    } catch (IOException e) {

        e.printStackTrace();

    }

Now I want to use spring-integration-http to replace the httpclient part.
I use int-http:inbound-gateway to receive the request,use service activator to treat the request and send out by int-http:outbound-gatewy.
inbound-gateway:

    <int:channel id="inchannel"/>

<int:channel id="respReply"/>

<int-http:inbound-gateway request-channel="inchannel" path="**" supported-methods="POST,GET"

                          reply-channel="respReply">

    <int-http:cross-origin/>

</int-http:inbound-gateway>

<int:service-activator input-channel="receiveChannel" ref="serviceActivator" method="serviceActivator"

                       output-channel="respReply"></int:service-activator>

my spirng integration outbond gateway is like this:

    <int:channel id='reply.channel'>

    <int:queue capacity='10'/>

</int:channel>

<int:channel id='request.channel'/>





<int-http:outbound-gateway id="outbound.gateway"

                           request-channel="request.channel" url-expression="headers.fwdUrl"

                           http-method-expression="headers.reqMethod"

                           charset="UTF-8" reply-timeout="5000" reply-channel="reply.channel"

>

my java code in activator

 private GatewaySerive gatewaySerive;

public Message<?> serviceActivator(Message<String> msg){

    MessageChannel outRequestChannel = context.getBean("request.channel", MessageChannel.class);

    PollableChannel outReplyChannel = context.getBean("reply.channel", PollableChannel.class);

    gatewaySerive.getSendOutMsg(msg); // add headers.fwdUrl headers.reqMethod in msg head

    try{

        outRequestChannel.send(enhanceMsg);

    }catch (Exception e){

        e.printStackTrace();

        System.out.println(e.getMessage());

    }

    Message<?> replyMesg = outReplyChannel.receive();

and I get the exception when send webservice request:

org.springframework.messaging.MessageHandlingException: HTTP request execution failed for URI [http://xxx.asmx]; nested exception is org.springframework.web.client.HttpServerErrorException: 500 Internal Server Error, failedMessage=GenericMessage [payload=60,63,120,109,108,32,118,101,114,115,105,111,xxxxxxxxxxx, headers={content-length=317, http_requestMethod=POST, errorChannel=org.springframework.messaging.core.GenericMessagingTemplate$TemporaryReplyChannel@348c0b2c, httpMethod=POST, replyChannel=org.springframework.messaging.core.GenericMessagingTemplate$TemporaryReplyChannel@348c0b2c, respUrl=http://xxx.asmx, host=localhost:8080, http_requestUrl=http://localhost:8080/httpGateway/ws/findPhonePlace, connection=Keep-Alive, id=7450b3a9-7432-8740-f5fa-0914dcbb1b81, contentType=application/soap+xml;charset=utf-8, accept-encoding=gzip,deflate, user-agent=Apache-HttpClient/4.5.6 (Java/1.8.0_131), timestamp=1547907719856}]

how can I slove this? I want to send webservice by spring-integration-http
