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：
