使用Dom4j生成xml文件（utf-8编码）

xml文件内容：

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

<result>
  <code>1</code>
  <data>
    <person>
      <name>张三</name>
      <id>1</id>
      <url>http://192.168.191.1:9999/TestWeb/c7fe21616d2a5e2bd1e84bd453a5b30f.jpg</url>
      <courses>
        <course>
          <courseName>语文</courseName>
          <courseMarks>90</courseMarks>
          <courseId>1</courseId>
        </course>
        <course>
          <courseName>数学</courseName>
          <courseMarks>80</courseMarks>
          <courseId>2</courseId>
        </course>
        <course>
          <courseName>英语</courseName>
          <courseMarks>70</courseMarks>
          <courseId>3</courseId>
        </course>
      </courses>
    </person>
    <person name="李四" id="2" url="http://192.168.191.1:9999/TestWeb/4052858c526002a712ef574ccae1948f.jpg">
      <course courseName="语文" courseMarks="91" courseId="1"/>
      <course courseName="数学" courseMarks="82" courseId="1"/>
      <course courseName="英语" courseMarks="73" courseId="1"/>
    </person>
  </data>
</result>

Java代码实现：

import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;

			createDocument().write( out );
			// 字符串控制台输出
			OutputFormat format = OutputFormat.createPrettyPrint();  //转换成字符串
			format.setEncoding("UTF-8");
			XMLWriter writer = new XMLWriter( System.out, format );
			writer.write( createDocument() );
		} catch (IOException e) {

				try {

	}
