我正在尝试从 java 中的 xlsx 表中检索日期单元格,并绑定以“MM/dd/yyyy”格式格式化数据
Cell celldate=row.getCell(2);
String value=formatter.formatCellValue(celldate);
CellType type=celldate.getCellType();
String dat=value;
if(dat!="") {
DateTimeFormatter inputFormat = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm a");
// Parsing the date
LocalDateTime date = LocalDateTime.parse(dat,inputFormat);
// Format for output
DateTimeFormatter outputFormat = DateTimeFormatter.ofPattern("MM/dd/yyyy");
// Printing the date
System.out.println(date.format(outputFormat));
但出现错误文本“时间”无法在索引 0 处解析
xlsx表
当我写入与表中写入的相同数据时,它正在工作
Cell cellname=row.getCell(7);
String stname=cellname.getStringCellValue();
Cell celldate=row.getCell(2);
String value=formatter.formatCellValue(celldate);
CellType type=celldate.getCellType();
String dat="12-09-2023 10:08 am";
if(dat!="") {
DateTimeFormatter inputFormat = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm a");
// Parsing the date
LocalDateTime date = LocalDateTime.parse(dat,inputFormat);
// Format for output
DateTimeFormatter outputFormat = DateTimeFormatter.ofPattern("MM/dd/yyyy");
// Printing the date
System.out.println(date.format(outputFormat));
通过添加此行解决了我的错误
Iterator <Row>rowiterator =sheet.iterator();
Row headerRow= rowiterator.next();
