Question

我试图在最近几天找出JAX-WS的一种令人感兴趣的行为。

基本上我从两个不同的客户端生成两个不同的SOAP请求，而且我无法对这些请求的创建方式进行任何更改。我仍然需要能够处理这两种类型的请求。

遗憾的是，第二个请求的请求参数在服务器上设置为NULL，尽管它在请求中发送时具有有效值。这意味着服务器无法正确解析此请求。如何告诉我的JAX-WS服务器正确处理这两个请求？

工作申请

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:getMachine xmlns:ns2="http://machine.soap.webservices.product.company.at/">
            <machineId>92623-15853588</machineId>
        </ns2:getMachine>
    </S:Body>
</S:Envelope>

已断开请求（服务器端参数为NULL）。

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <getMachine xmlns="http://machine.soap.webservices.product.company.at/">
            <machineId>92623-15853588</machineId>
        </getMachine>
    </S:Body>
</S:Envelope>

我似乎无法找到解决此问题的任何方法，尽管这个问题似乎已知很长一段时间了（See this 2 year old stackoverflow thread）。

完成后，这是我的WebService的实现。我尝试将目标命名空间直接设置为@WebService和@WebParam注释，但它没有效果。

package at.company.product.webservices.soap.machine;


import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;

import at.company.product.core.ProductCorePlugin;
import at.company.product.core.machine.IMachine;
import at.company.product.webservices.soap.exceptions.InvalidIdException;

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class WSMachineApi {

    @WebMethod
    public WSMachine getMachine(@WebParam(name = "machineId") String machineId) throws InvalidIdException{
        IMachine machine = getMachineById(machineId);
        if (machine == null){
            throw new InvalidIdException(machineId);
        }

        return new WSMachine(getMachineById(machineId));
    }   

    private IMachine getMachineById(String id) {
        return ProductCorePlugin.getDefault().getMachineHallAdmin().getMachineByID(id);
    }

}

您可能需要使用自定义SOAPHandler。示例显示here。使用自定义处理程序，您将能够轻松地调试此问题。

服务器上的有效JAX-WS请求参数为NULL
