java 读写 xml

  写xml

 

package xml;

import java.io.IOException;
import java.io.File;
import java.io.PrintStream;
import java.util.Properties;

public class propertiesTOXML {
    public static void main(String[] args) {

 Properties p = new Properties();
 
 p.setProperty("id","dean");
 
 p.setProperty("password","123456");

 try{
            PrintStream fW = new PrintStream(new File("e:\\test1.xml"));
            p.storeToXML(fW,"test");

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

        }

    }
}

 

读xml

 

package xml;

import java.io.File;
import java.io.FileInputStream;
import java.util.Iterator;
import java.util.Properties;

public class propertiesLoadXML {
    public static void main(String[] args) {

        File pFile = new File("e:\\test1.xml");    // properties文件放在e盘下（windows）
        FileInputStream pInStream = null;
        try {
            pInStream = new FileInputStream(pFile);
            Properties p = new Properties();
            p.loadFromXML(pInStream);
            //p.list(System.out);
            //另一个方法遍历
            Iterator iter = p.keySet().iterator();
      while(iter.hasNext()) {
       String key = (String)iter.next();
       String value = p.getProperty(key);
       String value2 = p.getProperty("30");
       
       System.out.println(key+"="+value);
      }
        } catch (Exception e) {
            e.printStackTrace(); 

        }

    }
}
