xml读取异常Invalid byte 1 of 1-byte UTF-8 sequence
说简单点当你解析别人的xml格式出现这个错误可能就是别人在生成xml时没有保存为utf-8的字符编码格式。
在中文版的window下java的默认的编码为GBK，也就是所虽然我们标识了要将xml保存为utf-8格式但实际上文件是以GBK格式来保存的，所以这也就是为什么能够我们使用GBK、GB2312编码来生成xml文件能正确的被解析，而以UTF-8格式生成的文件不能被xml解析器所解析的原因。
xml解析时遇到的编码异常：

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
[javascript]
copy
- SAXReaderreader=newSAXReader();
- org.dom4j.Documentdocument=reader.read("D:\\ha.xml");
- OutputFormatof=newOutputFormat();
- of.setEncoding("UTF-8");//改变编码方式
- XMLWriterwriter=newXMLWriter(newFileWriter"d:\\dom4j.xml"),of);
