XStream错误解决方案

我正在使用一个java应用程序来使用XStream解析一些XML。

XML是:

<object>
      <name>an Object Name</name>
      <ncss>154</ncss>
      <functions>48</functions>
      <classes>1</classes>
      <javadocs>44</javadocs>
    </object>

解析此内容时,我会得到以下错误:

Exception in thread "main" com.thoughtworks.xstream.converters.reflection.AbstractReflectionConverter$UnknownFieldException: No such field java.lang.Object.name

这是因为我的代码包含一个具有成员名称的Object类,但JDK引用的是java.lang.Object类,它没有这样的字段。

如何解决此冲突? 欢迎任何帮助。 提前谢谢。

编辑:相同的代码为:

package compareObjects.Logic;


    import java.io.BufferedReader;
    import java.io.File;
    import java.io.FileReader;
    import java.io.IOException;

import compareObjects.outPut.changedObjects;



    public class mainClass {

    public static void main(String[] args) throws IOException{

        BufferedReader br = new BufferedReader(new FileReader(new File("D:\\Object\\old_code_complexity.xml")));
        BufferedReader br2 = new BufferedReader(new FileReader(new File("D:\\Object\\new_code_complexity.xml")));

        String line;  //two strings to hold the old and new file's contents
        String line2;


        StringBuilder sb = new StringBuilder();
        StringBuilder sb2 = new StringBuilder();


        //Objects representing the output to be stored in XML Format

        changedObjects oPack = new changedObjects();

        // remove multiple occurrences of space in the xml input file old_code_complexity.xml
        while((line=br.readLine())!= null){
            sb.append(line.trim());
        }

        String x = sb.toString();

     // remove multiple consecutive occurrences of spaces in contents of new_code_complexity.xml

        //Create xstream instance to disable xstream from pushing extra _ character as escape sequence

        XStream xstream = new XStream(new DomDriver("UTF-8", new XmlFriendlyNameCoder("_-", " ")));

        // Create aliases to shorten class names in output file.


        xstream.alias("objects",Objects.class);

        Objects oList = (Objects)xstream.fromXML(x);

        String x2 = sb2.toString();
        Objects oList2 = (Objects)xstream.fromXML(x2);

           {

               if(oList.getObject(i).equals(oList2.getObject(j)))
                    {
                      oPack.addSimilarObject(((new changedObject("old_code_complexity.xml",oList.getObject(i),"new_code_complexity.xml",oList2.getObject(j)))));
                    }
            else
            {
                oPack.addChangedObject(((new changedObject("old_code_complexity.xml",oList.getObject(i),"new_code_complexity.xml",oList2.getObject(j)))));

            }

         }
          }



        }

        System.out.println(xstream.toXML(oPack));
        System.out.println("Objects Changed " + oPack.getDifferentObjects());
        System.out.println("Packages Not Changed" + oPack.getSimilarObjects());

    }
    }
