後端程式碼一：讀取xls檔案

public void readXls(InputStream path) throws IOException {
        HSSFWorkbook hssfWorkbook = new HSSFWorkbook(path);
        // 迴圈工作表Sheet
        for (int numSheet = 0; numSheet < hssfWorkbook.getNumberOfSheets(); numSheet++) {
            HSSFSheet hssfSheet = hssfWorkbook.getSheetAt(numSheet);
            System.out.println("總行數:" + ",總列數:" + hssfSheet.getLastRowNum());
            if (hssfSheet == null) {
                continue;
            }
            // 迴圈行Row
            for (int rowNum = 1; rowNum < hssfSheet.getLastRowNum(); rowNum++) {
                HSSFRow hssfRow = hssfSheet.getRow(rowNum);
                if (hssfRow != null) {
                    t = new ImportTitle();
                    HSSFCell title = hssfRow.getCell(0);
                    HSSFCell select1 = hssfRow.getCell(1);
                    HSSFCell score1 = hssfRow.getCell(2);
                    HSSFCell select2 = hssfRow.getCell(3);
                    HSSFCell score2 = hssfRow.getCell(4);
                    HSSFCell select3 = hssfRow.getCell(5);
                    HSSFCell score3 = hssfRow.getCell(6);
                    HSSFCell select4 = hssfRow.getCell(7);
                    HSSFCell score4 = hssfRow.getCell(8);
                    t.setTitles(getValue(title));
                    t.setSelect1(getValue(select1));
                    t.setSelect2(getValue(select2));
                    t.setSelect3(getValue(select3));
                    t.setSelect4(getValue(select4));
                    t.setScore1(getValue(score1));
                    t.setScore2(getValue(score2));
                    t.setScore3(getValue(score3));
                    t.setScore4(getValue(score4));

                    excelList.add(t);
                }
            }
        }
    }
 

後端程式碼二：servlet下使用讀取檔案

  /**
     * 匯入檔案
     */
    private void inportTitles(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        request.setCharacterEncoding("UTF-8");
        String territoryIds = null;
        Integer territoryId = 0;
        if (territoryIds != null && !territoryIds.equals("")) {
            territoryId = Integer.valueOf(territoryIds);
        }
        response.setContentType("text/html;charset=UTF-8");
        try {
            FileItemFactory factory = new DiskFileItemFactory();
            //檔案上傳核心工具類
            ServletFileUpload upload = new ServletFileUpload(factory);
            //單個檔案大小限制
            upload.setFileSizeMax(10 * 1024 * 1024);
            //總檔案大小限制
            upload.setSizeMax(50 * 1024 * 1024);
            //對中文編碼處理
            upload.setHeaderEncoding("UTF-8");

            if (ServletFileUpload.isMultipartContent(request)) {
                List<FileItem> list = upload.parseRequest(request);
                //遍歷
                for (FileItem item : list) {
                    String name = item.getFieldName(); // 獲取name屬性的值（必須要寫的，當前端的表單有text型別的資料時候），就這樣獲取表單的元素
                    String value = item.getString("utf-8"); // 獲取value屬性的值
                    if (name.equals("territory")) {
                        territoryIds = value;
                    }
                    if (!item.isFormField()) {
                        //讀取檔案
                        readXls(item.getInputStream());
                    }
                }
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        // 新增
     //處理新增進列表的資料
        }
    }
