解决:

1、最简单就是把<?xml version="1.0" encoding="UTF-8"?>改成<?xml version="1.0" encoding="gbk"?>

2、或者把xml打开另存的时候把字符集改为UTF-8后保存

3、在代码解析的时候先把xml重新写一遍

SAXReader reader = new SAXReader();  
  org.dom4j.Document document = reader.read("D:\\ha.xml");  
  OutputFormat of = new OutputFormat();  
  of.setEncoding("UTF-8"); //改变编码方式  
  XMLWriter writer = new XMLWriter(new FileWriter "d:\\dom4j.xml"), of);

4、直接dom4j读取的时候用io来读,修改字符编码

FileInputStream in = new FileInputStream(new File(fileName));
Reader read = new InputStreamReader(in,"gbk");
Document document = reader.read(read);
