未识别SOAP指定的类型

Question

我正在尝试使用带有VS2013 + .net 4.5的SOAP Web服务但是我在上面调用getVechicles方法时遇到异常，我找不到这个异常的原因。

我发现以下几点：

• 在异常结束时，我看到了一个可怕的事情，方法Read6_getVehiclesResponse正在调用Read3_Animal方法，而它应该尝试阅读Vehicle。
• 如果我删除Animal和Dog类型，一切正常。

例外：

ServiceReference.TestWebServiceClient client = new ServiceReference.TestWebServiceClient();
Animal[] sensors = client.getAnimals();
Vehicle[] vehicles = client.getVehicles(); //THIS LINE THROWS THE EXCEPTION

Answer 1

查看this链接我找到了解决方案，在服务器端（JAX-WS，Wildfly 8）我使用的是WSDL RPC/Literal样式，更改为Document/Literal解决了问题

原始代码：

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
public class TestWebService {

    @WebMethod
    public List<Vehicle> getVehicles() {
        return Arrays.asList(new Car() {{ setCarProp("CARP"); setVehicleProp("VEHP");}});
    }

    @WebMethod
    public List<Animal> getAnimals() {
        return Arrays.asList(new Dog());
    }
}

<强>修改：

@WebService
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT) //CHANGE FROM RPC TO DOCUMENT
@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
public class TestWebService {
...
