因此，我已将 csv 更改为 xls/xlsx，但每个单元格只有一个字符。我在我的 csv 中使用了 pipe(|) 作为分隔符。这是csv中的一行：4.0|sdfa@sdf.nb|plplplp|plplpl|plplp|1988-11-11|M|asdasd@sdf.ghgh|sdfsadfasdfasdfasdfasdf|asdfasdf|3.4253242E7|234234.0|true|true|
但在 excel 中，我得到了 4 。0 | sdfa
这是代码：
try {
String csvFileAddress = "manage_user_info.csv"; //csv file address
String xlsxFileAddress = "manage_user_info.xls"; //xls file address
HSSFWorkbook workBook = new HSSFWorkbook();
HSSFSheet sheet = workBook.createSheet("sheet1");
String currentLine=null;
int RowNum=0;
BufferedReader br = new BufferedReader(new FileReader(csvFileAddress));
while ((currentLine = br.readLine()) != null) {
String str[] = currentLine.split("|");
RowNum++;
HSSFRow currentRow=sheet.createRow(RowNum);
for(int i=0;i<str.length;i++){
currentRow.createCell(i).setCellValue(str[i]);
}
}
FileOutputStream fileOutputStream = new FileOutputStream(xlsxFileAddress);
workBook.write(fileOutputStream);
fileOutputStream.close();
System.out.println("Done");
} catch (Exception ex) {
System.out.println(ex.getMessage()+"Exception in try");
}
