基于Java创建XML（无中文乱码）过程解析

package com.zyb.xml; import java.io.FileOutputStream;import java.io.OutputStream;import java.io.OutputStreamWriter;import java.io.Writer; import org.dom4j.Document;import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.dom4j.io.OutputFormat;import org.dom4j.io.XMLWriter; public class TestXml2 {   public static void main(String[] args) throws Exception {    // TODO Auto-generated method stub    Document doc = DocumentHelper.createDocument();    //1.创建根节点    Element root = doc.addElement("books");    for(int i=0;i<2;i++){      //2.为根节点添加元素      Element book = root.addElement("book");      //3.如果有属性进行添加      book.addAttribute("id", "001");      //4.为元素继续添加元素      Element author = book.addElement("author");      Element price = book.addElement("price");      Element time = book.addElement("time");      //5.给对应元素赋值      author.addText("亚历山大");      price.addText("12.25");      time.addText("2015-09-05");    }     //良好的输出格式    OutputFormat format = OutputFormat.createPrettyPrint();    //6.//创建一个xml文件    OutputStream out = new FileOutputStream("src/book2.xml");    Writer wr = new OutputStreamWriter(out, "UTF-8");//用可改变编码的OutputStreamWriter代替了普通的FileWriter解决中文乱码问题     XMLWriter output = new XMLWriter(wr,format);     //7.将doc输出到xml文件中    output.write(doc);    //8.关闭资源    wr.close();     out.close();           output.close();  } }
