poi實現Excel匯入

    @Override
    public List<Student> importExcelStudent(String xlsPath) throws IOException {
        List<Student> students = new ArrayList<>();

            //獲得一個絕對路徑的流
            FileInputStream fileInputStream = new FileInputStream(xlsPath);
            //新建一個excel工作薄
            Workbook wb = new HSSFWorkbook(fileInputStream);
            //得到excel工作薄的第一個表單
            Sheet sheet = wb.getSheetAt(0);
            //迭代表單（遍歷每一行）
            for (Row row : sheet) {
                if (row.getRowNum() == 0) {
                    continue;
                }
                Student student = new Student();
                student.setName(row.getCell(0).getStringCellValue());
                student.setId(row.getCell(1).getStringCellValue());
                student.setAge((int)row.getCell(2).getNumericCellValue());
                student.setSex(row.getCell(3).getStringCellValue());
                students.add(student);
            }
            fileInputStream.close();
        return students;
    }
