如何获取CSV文件的编码方式

前几天刚做了一个 对文本文件分析编码方式以便正确转码
CodepageDetectorProxy detector = CodepageDetectorProxy.getInstance();
detector.add(UnicodeDetector.getInstance());
detector.add(JChardetFacade.getInstance());
detector.add(ASCIIDetector.getInstance());
File f = new File(url);
Charset charset = detector.detectCodepage(f.toURI().toURL());
//判断是否是UTF-8编码的文件
if("UTF-8".equals(charset.toString())){
br = new BufferedReader(new InputStreamReader(new FileInputStream(url),"UTF-8"));
} else {
br = new BufferedReader(new InputStreamReader(new FileInputStream(url),"GBK"));
}
可以判断的编码有不少 楼主可以输出试试看
cpdetector_1.0.10和 chardet （jchardet-1.1）这个是依赖jar包
