Setting a custom HTTP header dynamically with Spring-WS client

public class AddHttpHeaderInterceptor implements ClientInterceptor {public boolean handleFault(MessageContext messageContext)        throws WebServiceClientException {    return true;}public boolean handleRequest(MessageContext messageContext)        throws WebServiceClientException {     TransportContext context = TransportContextHolder.getTransportContext();     HttpComponentsConnection connection =(HttpComponentsConnection) context.getConnection();     connection.addRequestHeader("name", "suman");    return true;}public boolean handleResponse(MessageContext messageContext)        throws WebServiceClientException {    return true;}}

config:

    <bean id="webServiceTemplate" class="org.springframework.ws.client.core.WebServiceTemplate">    ...    <property name="interceptors">        <list>            <bean class="com.blah.AddHttpHeaderInterceptor" />        </list>    </property></bean>

ClientInterceptor works great for static header value. But it is not possible to use it when a different value should be applied per each request. In that case WebServiceMessageCallback is helpful:

final String dynamicParameter = //...webServiceOperations.marshalSendAndReceive(request,     new WebServiceMessageCallback() {        void doWithMessage(WebServiceMessage message) {            TransportContext context = TransportContextHolder.getTransportContext();            CommonsHttpConnection connection = (CommonsHttpConnection) context.getConnection();            PostMethod postMethod = connection.getPostMethod();            postMethod.addRequestHeader( "fsreqid", dynamicParameter );        }}

When using spring integration 3 and spring integration-ws, the following code can be used for handling the request:

public boolean handleRequest(MessageContext messageContext)        throws WebServiceClientException {    TransportContext context = TransportContextHolder.getTransportContext();    HttpUrlConnection connection = (HttpUrlConnection) context    .getConnection();    connection.getConnection().addRequestProperty("HEADERNAME",    "HEADERVALUE");    return true;}

The Interceptor can be connected to the outbound gateway in the following way:

<ws:outbound-gateway ...                    interceptor="addPasswordHeaderInterceptor" ></ws:outbound-gateway><bean id="addPasswordHeaderInterceptor class="com.yourfirm.YourHttpInterceptor" />
