dom4j 输出中文

简单示例：

xml输出为

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

<books>
  <book 作者="周国平" 出版社="东方出版社">守望的距离</book>
</books>

 Java代码为

	public static void createSimpleXml(){
		Document doc = DocumentHelper.createDocument();

		Element books = doc.addElement("books");

		Element book = books.addElement("book");
		book.addAttribute("作者", "周国平");
		book.addAttribute("出版社", "东方出版社");
		book.addText("守望的距离");

		try {
			OutputFormat format = new OutputFormat("  ", true, "utf-8"); // 设置输出格式为空两格，换行，编码为utf-8
			XMLWriter writer = new XMLWriter(new OutputStreamWriter(
					new FileOutputStream("d:/books.xml"), "utf-8"), format);//创建输出对象
			writer.write(doc);
			writer.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
