JAX-WS 复杂对象

Question

我正在sortedset.com（Apache CXF、TomEE）上试用 JAX-WS 示例，并对其进行了修改以包含一个复杂对象。我在org.apache.cxf.jaxb.Utils.getMethodXJTA(Utils.java:294) 收到NullPointerException。我的代码中是否缺少任何注释？还是有更多的事情要做来编组复杂的对象？

 import javax.jws.WebService; 

    @WebService(
            portName = "HelloTomEEPort",
            serviceName = "HelloTomEEService",
            targetNamespace = "http://sortedset.com/wsdl",
            endpointInterface = "HelloTomEEWs")
    public class HelloTomEEIMplementation implements HelloTomEEWs {

       public Person getPerson(){
            Person p =  new Person();
            p.setID(5);
            p.setName("Tom");
            return p;
        }

    }

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(targetNamespace = "http://sortedset.com/wsdl")
public interface HelloTomEEWs {
    @WebMethod    
    public Person getPerson();


}

import javax.xml.bind.annotation.XmlRegistry;

@XmlRegistry
public class Person{
 /**
     * 
     */
private int iD;
 private String name;
public int getID() {
    return iD;
}
public void setID(int iD) {
    this.iD = iD;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}

}

尝试使用@XmlType 而不是@XmlRegistry
