通过 JDOM 方式生成 XML 文档

　　　　　Element ele = new Element("tree");
ele.setAttribute("id","0");

Document document = new Document(ele);

Element e1 = new Element("name");
e1.setText("名称");
ele.addContent(e1);

//        Format format = Format.getCompactFormat();//xml格式
Format format = Format.getPrettyFormat();//xml格式
//        format.setIndent("");//设置换行，getPrettyFormat不用设
format.setEncoding("GBK");

XMLOutputter outputter = new XMLOutputter(format);
try {
outputter.output(document, new FileOutputStream(new File("jdomTest.xml")));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

<?xml version="1.0" encoding="GBK"?>
<tree id="0">
<name>名称</name>
</tree>
