JDomOutput.java代码如下
----------------------------------------------------------------------------------------------------------------------
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.jdom.Attribute;
import org.jdom.Comment;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.output.Format;
import org.jdom.output.XMLOutputter;
public class JDomOutput
{
public static void main(String[] args) throws IOException
{
//创建文档
Document document = new Document();
//创建根元素
Element people = new Element("people");
//把根元素加入到document中
document.addContent(people);

//创建注释
Comment rootComment = new Comment("将数据从程序输出到XML中！");
people.addContent(rootComment);

//创建父元素
Element person1 = new Element("person");
//把元素加入到根元素中
people.addContent(person1);
//设置person1元素属性
person1.setAttribute("id", "001");

Attribute person1_gender = new Attribute("gender", "male");
person1.setAttribute(person1_gender);

Element person1_name = new Element("name");
person1_name.setText("刘德华");
person1.addContent(person1_name);

Element person1_address = new Element("address");
person1_address.setText("香港");
person1.addContent(person1_address);

Element person2 = new Element("person");
people.addContent(person2);

person2.setAttribute("id", "002").setAttribute("gender","male");//添加属性，可以一次添加多个属性

Element person2_name = new Element("name");
person2_name.setText("林志颖");
person2.addContent(person2_name);

Element person2_address = new Element("address");
person2_address.setText("台湾");
person2.addContent(person2_address);

//设置xml输出格式
Format format = Format.getPrettyFormat();
format.setEncoding("utf-8");//设置编码
format.setIndent(" ");//设置缩进

//得到xml输出流
XMLOutputter out = new XMLOutputter(format);
//把数据输出到xml中
out.output(document, new FileOutputStream("jdom.xml"));//或者FileWriter

}
}
---------------------------------------------------------------------------------------------------------------------------

生成的xml内容如下：
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<people>

<person id="001" gender="male">
<name>刘德华</name>
<address>香港</address>
</person>
<person id="002" gender="male">
<name>林志颖</name>
<address>台湾</address>
</person>
</people>
