使用时元帅异常 jaxb

我有一个代码 java, 而且我正在尝试拆卸它并以文件的形式保存 XML 在我的 PC, 使用 JAXB, 但我有一个例外编组：

Exception in thread "main" javax.xml.bind.MarshalException

 - with linked exception:

[com.sun.istack.internal.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation]

代码 JAXB, 我使用了 :

import java.io.File;

import java.io.IOException;

import java.util.List;

import javax.xml.bind.JAXBContext;

import javax.xml.bind.JAXBException;

import javax.xml.bind.Marshaller;

import javax.xml.bind.Unmarshaller;

 public class ConfList {



 private static final String fileName = "Source.xml";

 List<string> xmlConfList;

 private Object object;



 public ConfList/Object object/{

 this.object = object;

 }



 public void addToList// throws IOException, JAXBException {



 File file = new File/fileName/;

 JAXBContext jaxbContext = JAXBContext.newInstance/XmlConf.class/;

 Marshaller jaxbMarshaller = jaxbContext.createMarshaller//;



 jaxbMarshaller.setProperty/Marshaller.JAXB_FORMATTED_OUTPUT, true/;



 jaxbMarshaller.marshal/object, file/; // i got the exception here

 jaxbMarshaller.marshal/object, System.out/;



 }

 }

我使用的主类：

import java.io.IOException;

import java.util.ArrayList;

import javax.xml.bind.JAXBException;

import javax.xml.parsers.ParserConfigurationException;

import javax.xml.transform.TransformerException;

import javax.xml.xpath.XPathExpressionException;



import org.xml.sax.SAXException;



public class Tester{



 public static void main /String [] args/ throws XPathExpressionException, IOException, ParserConfigurationException, SAXException, TransformerException, JAXBException{



 work//;



 }



 public static void work // throws IOException, ParserConfigurationException, SAXException, XPathExpressionException, TransformerException, JAXBException{

 XmlSource xml = new XmlSource/surl/;

 xml.validate//;

 xml.load//;

 ArrayList<string> paths = xml.getAllPaths//;



 for/String path : paths/{

 System.out.println/path/;

 }



 ConfList v = new ConfList/xml.getXml///;

 v.addToList//;



 }

}

班级 XmlConf :

import java.net.URL;

import java.util.ArrayList;

import java.util.List;

import java.util.Map;

import javax.xml.bind.annotation.XmlAttribute;

import javax.xml.bind.annotation.XmlElement;

import javax.xml.bind.annotation.XmlRootElement;



@XmlRootElement/name = "XmlSource"/

public class XmlConf {



 private URL url;

 private List<string> path = new ArrayList<string>//;

 private String urlp;

 private Map<string, string=""> parameters;

 private String host;





 public URL getUrl// {

 return url;

 }

 @XmlAttribute/name = "URL"/

 public void setUrl/URL url/ {

 this.url = url;

 }

 @XmlElement

 public List<string> getPath// {

 return path;

 }

 public void setPath/String path/ {

 this.path.add/path/;

 }

 @XmlElement

 public void setUrlPath/String urlp/{

 this.urlp = urlp;

 }

 public String getUrlPath//{

 return urlp;

 }

 public void setParameters/Map<string, string=""> parameters/{

 this.parameters = parameters;

 }

 public Map<string, string=""> getParameters//{

 return parameters;

 }

 public void setHostName/String host/{

 this.host = host;

 }

 public String getHostName//{

 return host;

 }

}

请注意所有方法 /XmlSource class/ 正确执行。
