Java JAXB映射到对象而不是字符串

我有以下XML：

<game name="m1itskow" sourcefile="maygay1bsw.c" ismechanical="yes" cloneof="m1itsko" romof="m1itsko">
    <description>It's A Knockout (Maygay) (M1A/B) (set 24)</description>
    <year>199?</year>
    <manufacturer>Maygay</manufacturer>
</game>

这是一场淘汰赛（梅盖）（M1A/B）（第24集）
199?
梅盖

今天，我在游戏类中将制造商作为字符串，但我需要映射到制造商类，我应该怎么做？可能吗？谢谢

编辑：无法更改XML，因为这是由第三方工具生成的文件。

对XML结构进行了更改

XML

manufacturer.java

我

main.java

import javax.xml.bind.JAXBContext;  
import javax.xml.bind.JAXBException;  
import javax.xml.bind.Unmarshaller;  

public class SampleTest {  
public static void main(String[] args) {  
     try {    
            File file = new File("employee.xml");    
            JAXBContext jaxbContext = JAXBContext.newInstance(game.class);    
            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();    
            game e=(game) jaxbUnmarshaller.unmarshal(file);    
            System.out.println(e.getManufacturer().getName());  

          } 
     catch (JAXBException e) {
         e.printStackTrace(); 
         }    
     }

}

只是忘了提到我不能更改XML。这是一个生成的文件，我无法手动更改它（它有30000多个条目）
