org.dom4j.DocumentException: no protocol

代码如下:

 public Document getDocumentByString(String xml) {
  SAXReader sax = new SAXReader();
  Document xmlDoc = null;
  try {
   xmlDoc = sax.read(xml);
  } catch (UnsupportedEncodingException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (DocumentException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return xmlDoc;
 }

DOM4J 解析XML时出现以下问题:

怎么解决哦?????

 原因是XML文件和开发环境的编码问题.

将xmlDoc = sax.read(xml)改成:

xmlDoc = sax.read(new ByteArrayInputStream(xml.getBytes("UTF-8")));

这里保证编码的一致.就可以了!
