xml讀取異常Invalid byte 1 of 1-byte UTF-8 sequence

說簡單點當你解析別人的xml格式出現這個錯誤可能就是別人在生成xml時沒有保存為utf-8的字符編碼格式。

在中文版的window下java的默認的編碼為GBK，也就是所雖然我們標識了要將xml保存為utf-8格式但實際上文件是以GBK格式來保存的，所以這也就是為什么能夠我們使用GBK、GB2312編碼來生成xml文件能正確的被解析，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解析時遇到的編碼異常：

1、最簡單就是把<?xml version="1.0" encoding="UTF-8"?>改成<?xml version="1.0" encoding="gbk"?>

2、或者把xml打開另存的時候把字符集改為UTF-8后保存

3、在代碼解析的時候先把xml重新寫一遍

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

4、直接dom4j讀取的時候用io來讀，修改字符編碼

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