Spring WS Endpoint extract SOAP info

Question

After reading doc on the Spring web site, still confused about how to extract information from a SOAP request. For example, the SOAP request sent to server is like:

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope" xmlns:user="http://www.mysite.com/user/schemas">
   <soapenv:Header/>
   <soapenv:Body>
      <user:UserRequest>
         <!--You may enter the following 4 items in any order-->
         <user:Key>key</user:Key>
         <user:UserName>username</user:UserName>
         <user:RequesterName>reqname</user:RequesterName>
         <user:RequesterPassword>repw</user:RequesterPassword>
      </user:UserRequest>
   </soapenv:Body>
</soapenv:Envelope>

On my server side I create an Endpoint like:

@Endpoint
public class UserEndpoint {

    private static final String NAMESPACE_URI = "http://www.mysite.com/user/schemas";

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "UserRequest")
    public void handleGetUserRequest() {
//Extract here...
    }   
}

How should I write extraction code here?

Answer 1

I would suggest having a look at the Spring WS samples for code ideas, depending on what else you are using in your application. For example: the HolidayEndpoint source code .

Answer 2

@Endpoint("myEndpoint")
public class MyEndpoint {

    /**
     * Spring-WS Endpoint 
     * @param submitSomethingRequest 
     * @param header
     * @return SubmitSomethingResponse
     */
    @PayloadRoot(namespace="http://my.namespace.org/spec/1.0.1", localPart="submitSomethingRequest")
    @ResponsePayload
    public SubmitSomethingResponse submitSomethingRequest(@RequestPayload SubmitSomethingRequest submitSomethingRequest, **SoapHeader header**) {
        LOG.info("Received SOAP HEADER: " + header);
        if(header != null) {
            Iterator<SoapHeaderElement> hdrs = header.examineAllHeaderElements();
            while(hdrs.hasNext()) {
                SoapHeaderElement hdrEle = hdrs.next();
                System.out.prinltn(hdrEle.getName().getPrefix() + ":" + hdrEle.getName().getLocalPart());
                 ... //Do something here to parse DOM and extract headers you care about
            }
        }
...
