Question

如何将接口指定为参数/返回类型，而不是具体的Java POJO类用于Web服务操作。？

@XmlSeeAlso注释也不起作用。

数据类型界面：

public interface MyInput {
    public String getName() ;
    public void setName(String name);
}

public interface MyOutput{
    public String getResult() ;
    public void setResult(String result);
}

数据类型实施：

public class MyInputDataType implements MyInput {
     private String name;
      ...

     public String getName(){
        return this.name ;
     }

     public void setName(String name){
        this.name = name 
     }

 }



public class MyOutputDataType implements MyOutput{
     private String result;
       ...

     public String getResult(){
         return this.result;
      }

      public void setResult(String result){
         this.result= result
      }
 }

Web服务合同：

@WebService(name="MyWebService", portName="MyWebService", targetNamespace="http://somename.org", serviceName="MyWebService")
public interface MyWebService {
    @WebMethod
   public MyOutput executeOperation(MyInput  input) ;
 }

Web服务实现：

@WebService( portName="MyWebService", name="MyWebService", targetNamespace="http://somename.org", serviceName="MyWebService", endpointInterface="MyWebService")
public class MyWebServiceImpl implements MyWebService
{
      public MyOutput executeOperation(MyInput  input)
      {
          MyOutput output = new MyOutputDataType();
          output.setResult("executeOperation with input: " +  input.getName() );
          return output;
       }

 }

部署在WL 12c（JEE 6），JDK7

例外：

Exception Description: An error occurred unmarshalling the document
Internal Exception: org.xml.sax.SAXParseException; lineNumber: 0; columnNumber: 0;
Exception Description: The instance creation method [MyInput.<Default Constructor>],   with no parameters, does not exist, or is not accessible.
Internal Exception: java.lang.NoSuchMethodException: MyInput.<init>()
Descriptor: XMLDescriptor(MyInput --> [])]

具有复杂数据类型接口的Web服务而不是POJO类作为服务参数/返回类型
