Invalid byte 1 of 1-byte UTF-8 sequence 異常分析和解決
“org.dom4j.DocumentException: Invalid byte 1 of 1-byte UTF-8 sequence.”異常分析和解決:
分析:
該異常由下面的reader.read(file);語句拋出:
SAXReader reader = new SAXReader();
Document doc = reader.read(file);
產生這個異常的原因是:
所讀的xml文件實際是GBK或者其他編碼的,而xml內容中卻用<?xml version="1.0" encoding="utf-8"?>指定編碼爲utf-8,所以就報異常了!
解決方法:
在解析XML前,將XML編碼爲UTF-8。
如:req.setCharacterEncoding("UTF-8");
如:new ByteArrayInputStream(submitDataParam.getBytes("UTF-8"))
Invalid byte 2 of 2-byte UTF-8 sequence 異常分析和解決
byte[] bytes = requestMsg.getBytes();
InputStream in = new ByteArrayInputStream(bytes);
InputStreamReader strInStream = new InputStreamReader(in, "GBK"); //即在讀流時指定編碼
Document document = saxReader.read(strInStream);
