HAP自定义Excel导入

• 项⽬配置 编辑 src/main/resources/spring/applicationContext-beans.xml ⽂件，并添加以下内容：

    
        
        
            104857600
        
        
            4096
        
    

• 前端定义上传 Excel 的表单

        

            

                

                    
                    
                    
                    
                    
                    
                        <@spring.message "自定义导入"/>
                
            
        
        

• 前端增加库引⽤
  将最新版的 jquery-form 库⽂件放置在 src/main/webapp/resources/js/jquery-form/jquery-form.js
  没有文件夹自己新建一个

• 前端⻚⾯增加导⼊⽅法
  在一个添加下面代码，当点击“自定义导入"按钮后调用importExcel()方法，importExcel()将数据传送到后台

/**
 *Call api to import excel asynchronously
 */
   function importExcel() {
                      $('#formUpload').ajaxSubmit({
                                dataType: 'json',
                                success: function (data) {
                                    if (data.success) {
                                        kendo.ui.showInfoDialog({
                                            message: data.message
                                        });
                                    } else {
                                        kendo.ui.showErrorDialog({
                                            message: data.message
                                        });
                                    }
                                }
                            });
                        }

• 在控制器层添加 RESTful api 路径和⽅法

/***自定义导入*****/
    @RequestMapping(
            value = {"/wht/ora/20796/org/access/export/excel/import/custom"},
            method = {RequestMethod.POST}
    )
    public ResponseData uploadExcel(HttpServletRequest request, Locale locale, String
            contextPath) throws Exception {
        ResponseData rd = new ResponseData();
        IRequest requestCtx = createRequestContext(request);
        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)
                request;
        MultipartFile file = multipartRequest.getFile("upfile");
        if (file == null || file.isEmpty()) {
            rd.setSuccess(false);
            rd.setMessage("File is empty!");
            return rd;
        }
        InputStream in = file.getInputStream();
      //importExcel()方法在下面的IOra20796OrgAccessService定义
        return service.importExcel(in, file.getOriginalFilename());
    }

• 添加导⼊ Excel 的服务⽅法
  先在IOra20796OrgAccessService 接口中定义importExcel()

public interface IOra20796OrgAccessService extends IBaseService, ProxySelf {
    List selectOrgAccessByOrder(IRequest iRequest, Ora20796OrgAccess dto, int page, int pageSize);
    ResponseData importExcel(InputStream is, String fileName) throws Exception;
}

再在Ora20796OrgAccessServiceImpl中实现importExcel()

@Service
@Transactional(rollbackFor = Exception.class)
public class Ora20796OrgAccessServiceImpl extends BaseServiceImpl implements IOra20796OrgAccessService {

    @Autowired
    private Ora20796OrgAccessMapper orgAccessMapper;
    @Autowired
    private ObjectMapper objectMapper;
    private final static String excel2003L =".xls";    //2003- 版本的excel
    private final static String excel2007U =".xlsx";   //2007+ 版本的excel

    @Override
    public List selectOrgAccessByOrder(IRequest iRequest, Ora20796OrgAccess dto, int page, int pageSize) {
        PageHelper.startPage(page, pageSize);
        return orgAccessMapper.selectOrgAccessByOrder(dto);
    }

    /***自定义导入****/

    public ResponseData importExcel(InputStream is, String fileName) throws Exception {
        ResponseData rd = new ResponseData();
        List> list = new ArrayList>();
// Create a new workbook
        Workbook workbook = null;
        String fileType = fileName.substring(fileName.lastIndexOf("."));

        if (excel2003L.equals(fileType)) {
            workbook = new HSSFWorkbook(is); //2003-
        } else if (excel2007U.equals(fileType)) {
            workbook = new XSSFWorkbook(is); //2007+
        } else {
            throw new Exception("解析的⽂文件格式有误！");
        }
        Sheet worksheet = null;
        Row row = null;
        Cell cell = null;
//遍历Excel中所有的sheet
        for (int i = 0; i < workbook.getNumberOfSheets(); i++) {
            worksheet = workbook.getSheetAt(i);
            if (worksheet == null) {
                continue;
            }
//遍历当前sheet中的所有⾏行行
            for (int j = worksheet.getFirstRowNum(); j < worksheet.getLastRowNum() + 1; j++) {
                row = worksheet.getRow(j);
// 跳过空⾏行行和标题⾏行行（第⼀一⾏行行）
                if (row == null || row.getFirstCellNum() == j) {
                    continue;
                }
//遍历所有的列列
                List
