Question

我正在开发一个Web服务，它将输入参数作为两个字符串值。第一个标识用于导入xml数据的服务，第二个标识XML数据字符串。以下是SOAP请求的示例

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://webservices.dataexchange.xxx.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <web:importDataExchange>
         <ServiceID>XmlImportServiceName</ServiceID>
         <ExchangeData><?xml version="1.0" encoding="UTF-8"?><srv:exchange xmlns:cnt="Container" xmlns:core="Core" xmlns:srv="Service" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="Service http://xxx/xxx.xsd"></srv:exchange></ExchangeData>
      </web:importDataExchange>
   </soapenv:Body>
</soapenv:Envelope>

不幸的是，每当我尝试解析SOAPMessage时，都会收到以下错误：

javax.xml.bind.UnmarshalException
 - with linked exception:
[com.ctc.wstx.exc.WstxParsingException: Illegal processing instruction target ("xml"); xml (case insensitive) is reserved by the specs.
 at [row,col {unknown-source}]: [6,28]]

这显然是因为我实现的JAX-WS正试图解组<ExchangeData>元素的内容。当然，这可以通过将<ExchangeData>的内容包装在<![CDATA[ ]]>元素中来解决，但是，我无法控制数据如何发送到服务器。因此，我需要一种方法来拦截SOAPMessage并将ExchangeData作为字符串提取而不使用Unmarshalling它。或者，我需要一种方法让Web服务将ExchangeData节点的内容视为字符串而不是SOAPMessage主体/有效负载中的另一个XML节点。

我尝试过实现SOAPHandler和LogicalHandler，但是在两个实例中，只要获取Message / Payload，Web服务器就会尝试解组SOAP消息，这会再次重现相同的错误。

这是我迄今为止开发的ImportServiceEndpoint。

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.context.support.SpringBeanAutowiringSupport;

@WebService(serviceName = "ImportServiceEndpoint", portName = "dataexchange")
// @HandlerChain(file = "handlers.xml")
public class ImportServiceEndpoint extends SpringBeanAutowiringSupport {

    private static final Logger LOGGER = LoggerFactory.getLogger(ImportServiceEndpoint.class);

    /**
     * The soap implementation of the data exchange service.
     * 
     * @param serviceID
     *          the id of the service
     * @param exchangeData
     *          the xml data for the request.
     * @return a response about the success/failure of the dataexchange.
     */
    @WebMethod
    @WebResult(name = "importDataExchangeResponse")
    public String importDataExchange(@ModelAttribute("ServiceID") @WebParam(name = "ServiceID") final String serviceID,
            @ModelAttribute("ExchangeData") @WebParam(name = "ExchangeData") final String exchangeData) {
        LOGGER.debug("Recevied Soap request for service {} with xml data '{}'", serviceID, exchangeData);
        return "Message Received";
    }
}

如果有任何帮助，我将不胜感激。我已经非常沮丧，因为我已经在这几天工作了几天没有什么可展示的。
