生成的csv文件，设置为UTF-8格式，在windows上用EXCEL打开的话会乱码，在linux上用vim或者cat打开查看正常；设置为GBK格式的话，在windows上用EXCEL打开正常，但在linux上乱码
File file = new File(ospFileName);
OutputStream stream = new FileOutputStream(file);
stream.write(newbyte[] { (byte) 0xEF, (byte) 0xBB, (byte) 0xBF });
CsvWriter ospWriter = new CsvWriter(stream, ‘,‘, Charset.forName("UTF-8"));
String[] ospHead = new String[]{"No","Comment","server","method","param-exp","response","trace-id"};
ospWriter.writeRecord(ospHead);
这样的话，在windows上用EXCEL打开就不会是乱码，linux上也显示正常；
