Description
public static Pair<ExcelWriter, WriteSheet> buildCsvWriter(File file, String sheetName, Charset charset) { ExcelWriter excelWriter = EasyExcel.write(file).charset(charset).build(); WriteSheet writeSheet = new WriteSheet(); writeSheet.setSheetName(sheetName);
return Pair.of(excelWriter, writeSheet);
}
再生成文件写入句柄的时候，设置了utf-8编码格式，但是生成文件无法带bom头， tempFile = File.createTempFile(SESSION_DETAIL_FILE_NAME + System.currentTimeMillis(), ".csv",dir); fos = new FileOutputStream(tempFile.getPath()); fos.write(new byte[]{(byte)0xEF, (byte)0xBB, (byte)0xBF}); fos.flush(); 在获取句柄前单独写入也不行 会话明细17272333965255218563994055952976.csv: Unicode text, UTF-8 text, with CRLF line terminators
所以我该如何生成一个带有bom头的csv文件呢？
