Java 如何从soap服务请求中检索xml

我有下面的服务，需要检索订单的xml以在数据库中注册

@Override
@WebMethod(operationName = "retrieveData")
@WebResult(name = "RetrieveDataOut")
public RetrieveDataOut retrieveData(
        @WebParam(name = "RetrieveDataIn", targetNamespace = TARGET_NAME_SPACE) RetrieveDataIn in,
        @WebParam(name = "header", targetNamespace = "http://www.company.com/common", header=true) Header header) throws XXXServiceResponseFault {
        
    
    return retrieveDataController.retrieveData(in, header); 
}

I searched here on the internet but didn't find it, I think there is a tag that encapsulates this. Example `@WebInBound`.

Any Ideia ?

Thanks in advance.
