Invalid byte 1 of 1-byte UTF-8 sequence 异常分析和解决
“org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence.”异常分析和解决:
分析:
该异常由下面的reader.read(file);语句抛出:
SAXReader reader = new SAXReader();
Document doc = reader.read(file);
产生这个异常的原因是:
所读的xml文件实际是GBK或者其他编码的,而xml内容中却用指定编码为utf-8,所以就报异常了!
解决方法:
在解析XML前,将XML编码为UTF-8。
如:req.setCharacterEncoding("UTF-8");
如:new ByteArrayInputStream(submitDataParam.getBytes("UTF-8"))
Invalid byte 2 of 2-byte UTF-8 sequence 异常分析和解决
原因:
saxReader.read()读取的流中包含中文报错:
解决:
SAXReader saxReader =newSAXReader();
byte[] bytes = requestMsg.getBytes();
InputStream in =newByteArrayInputStream(bytes);
InputStreamReader strInStream =newInputStreamReader(in,"GBK"); //即在读流时指定编码
Document document = saxReader.read(strInStream);
