java webservice中继承的类

Question

我有一个场景，我想让所有返回对象继承基类。在下面的场景中，BaseResponse是webservice返回的所有响应的基类。将有许多webmethods，每个人都将拥有它自己的返回对象。一个这样的例子在下面的代码中

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "BaseResponse", propOrder = { "state"})
public class BaseResponse {
   private Integer state; 

    public Integer getState(){
       return state; 
    }

    public void setState(Integer state){
        this.state = state;
    }
}


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "XXXActionResponse ", propOrder = { "data1", "data2"})
public class XXXActionResponse extends BaseResponse {
    private String data1;
    private String data2;

    public String getData1(){
        return data1;
    }

    public String getData2(){
        return data2;
    }

    public void setData1(String data1){
        this.data1=data1;
    }

    public void setData2(String data2){
        this.data2 = data2;
    }

}

我的网络服务

@WebService
public class MyService{

@WebMethod
public XXXActionResponse DoXXXAction() 
    throws Exception {

    XXXActionResponse resp = new XXXActionResponse();
    resp.setData1("Data1");
    resp.setData2("Data2");
    resp.setState(0);
    Return resp;

}

这是创建只有Data1和Data2的Jaxb对象。 请解释如何序列化state属性？
