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>
