为什么不接受 startElement 方法？

Question

我正在测试 SaxParser 并重写了 DefaultHandler 及其方法！出于某种原因，我无法覆盖方法 "startElement"。它没有事件开始。我用 syso 命令测试了它。有人能解决我的问题吗？提前致谢！

import java.io.File;
import java.io.IOException;
import java.util.LinkedList;
import java.util.jar.Attributes;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

public class Parserusw {

    static LinkedList<String>list = new LinkedList<String>();

    public static void main(String[]args) throws ParserConfigurationException, SAXException{
        SAXParserFactory factory = SAXParserFactory.newInstance();
        SAXParser saxParser = factory.newSAXParser();
        DefaultHandler handler = new DefaultHandler(){


        @Override
          public void startElement(String uri, String localName,String qName,Attributes attributes) throws SAXException{
            if(qName.equals("Start"))
                Parserusw.list.add("Start");
            Parserusw.list.add("Start1");
            Parserusw.list.add("Start2");
            System.out.println("uidwwd");

        }
        @Override
        public void characters(char[] ch, int start, int length) throws SAXException {
            String text;
            text = String.valueOf(ch, start, length);

            if(text.equals("Ende"))
                Parserusw.list.add("Ende");


        }
        @Override
        public void endElement (String namespaceURI,String localName, String qName){
            for(String s:Parserusw.list){
                System.out.println(s);
            }
            System.out.println("uidwwd");
        }
    };

    try {
        saxParser.parse(new File("c:\Users\User\GP\Arbeit\src\iwasmitparser\test.xml"),handler);
    } catch (IOException e) {

        e.printStackTrace();
    }



}

}

你输入错了Attributes class:

import java.util.jar.Attributes;

应该是org.xml.sax的那个。

为什么不接受 startElement 方法？

Why is the startElement method not being accepted?

xml

parsing

overriding

sax
