XML04-DOM4J引入-----------------01

Hibernate使用Dom4j来读取配置文件

DOM4j生成的xml是格式化的，而jdom不是

Dom4j的源码是一个文件夹

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public class DOM4J01 {

	public static void main(String[] args) {
		Document document=DocumentHelper.createDocument();
		Element studentElement=document.addElement("student");
		studentElement.addAttribute("id", "001");
		studentElement.addAttribute("aa", "xx");
		
		Element name=studentElement.addElement("name");
		name.setText("郑恒");
		Element sex=studentElement.addElement("sex");
		sex.setText("男");
		Element age=studentElement.addElement("age");
		age.setText("24");
		OutputFormat format=OutputFormat.createPrettyPrint();
		format.setEncoding("UTF-8");
		try {
			XMLWriter writer=new XMLWriter(new FileOutputStream("src/student041.xml"),format);
			writer.write(document);
			writer.close();
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

创建一个XML文件：

<?xml version="1.0" encoding="UTF-8"?>

<student id="001" aa="xx">
  <name>郑恒</name>
  <sex>男</sex>
  <age>24</age>
</student>
