java – 来自Webservice编组错误的JAXB类

我有一些wsimport生成的JAXB类

wsimport -d src/main/java -keep -extension
  -p my.package
  http://www.OpenLigaDB.de/Webservices/Sportsdata.asmx?WSDL

我将演示这个类的问题(我自己只添加了@XmlRootElement)：

package my.package;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Sport",propOrder = {"sportsID","sportsName"})
@XmlRootElement(name = "sport")   //Added by myself
public class Sport
{
    protected int sportsID;
    protected String sportsName;

    public int getSportsID() {return sportsID;}
    public void setSportsID(int value) {this.sportsID = value;}

    public String getSportsName() {return sportsName;}
    public void setSportsName(String value) {this.sportsName = value;}
}

直接实例化和编组工作正常(例1)

Sport sport = new Sport();
sport.setSportsID(1);
sport.setSportsName("test");

JAXBContext jc = JAXBContext.newInstance(Sport.class);
jc.createMarshaller().marshal(sport,System.out);

现在让我们在webservice调用中创建对象：

SportsdataSoap s = new Sportsdata().getSportsdataSoap();
ArrayOfSport sports = s.getAvailSports();

for(Sport sport : sports.getSport())
{
    JAXBContext jc = JAXBContext.newInstance(Sport.class);
    jc.createMarshaller().marshal(sport,System.out);
}

然后我得到了这个例外：

Exception in thread "main" java.lang.ClassCastException: my.package.Sport$JaxbAccessorF_sportsID cannot be cast to com.sun.xml.bind.v2.runtime.reflect.Accessor

怎么处理这个？谢谢你,托尔.

更新2如果我修改Example1到此,我得到相同的错误

SportsdataSoap s = new Sportsdata().getSportsdataSoap();

Sport sport = new Sport();
sport.setSportsID(1);
sport.setSportsName("test");

JAXBContext jc = JAXBContext.newInstance(Sport.class);
jc.createMarshaller().marshal(sport,System.out);

更新2体育的XML结构

<Sport>
  <sportsID>int</sportsID>
  <sportsName>string</sportsName>
</Sport>

解决方法
