我正在尝试在我的JAX-WS Web服务中创建通用列表包装器。
这是我服务的数据模型：
@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
public class Person {
@XmlElement(required = true)
private int personId;
@XmlElement(required = true)
private String personName;
public int getPersonId() {
return personId;
}
public void setPersonId(int personId) {
this.personId = personId;
}
public String getPersonName() {
return personName;
}
public void setPersonName(String personName) {
this.personName = personName;
}
}
@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
public class GenericList <T> {
@XmlAnyElement
private List<T> item;
public GenericList() {
item = new ArrayList<T>();
}
public List<T> getItem() {
return item;
}
public void setItem(List<T> item) {
this.item = item;
}
}
@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
public class Application {
@XmlElement(required = true)
private int applicationId;
@XmlElement(required = true)
private GenericList<Person> personList;
public int getApplicationId() {
return applicationId;
}
public void setApplicationId(int applicationId) {
this.applicationId = applicationId;
}
public GenericList<Person> getPersonList() {
return personList;
}
public void setPersonList(GenericList<Person> personList) {
this.personList = personList;
}
}
这是我的网络服务代码：
@WebService(serviceName = "TestWs")
public class TestWs {
@WebMethod
@WebResult(name = "response")
public Application getApplication(@WebParam(name = "request") int applicationId) {
Application app = new Application();
app.setApplicationId(applicationId);
GenericList<Person> personList = new GenericList<Person>();
Random rand = new Random();
Person p1 = new Person();
p1.setPersonId(rand.nextInt(100));
p1.setPersonName("Random 1");
personList.getItem().add(p1);
Person p2 = new Person();
p2.setPersonId(rand.nextInt(100));
p2.setPersonName("Random 2");
personList.getItem().add(p2);
Person p3 = new Person();
p3.setPersonId(rand.nextInt(100));
p3.setPersonName("Random 3");
personList.getItem().add(p3);
app.setPersonList(personList);
return app;
}
}
当我尝试调用Web服务方法getApplication时，我收到以下错误：

你能解释一下我做错了什么，以及如何正确创建通用列表包装器？
