BOS系统开发笔记(6)---区域的批导入(Jquery OCUpload+Apache POI处理)

1、RegionAction完成POI处理

@Controller
  public class RegionAction {
 +	@Autowired
 +	private RegionService regionService;
 +	
  	//属性驱动接受上传的文件
  	private File regionFile;
  	public void setRegionFile(File regionFile) {
 @@ -24,8 +40,39 @@ public void setRegionFile(File regionFile) {
  	 * @Description: 导入表格
  	 * @date: 2018年7月12日 下午1:31:31
  	 * @return
 +	 * @throws IOException 
 +	 * @throws FileNotFoundException 
  	 */
 -	public String importXls(){
 +	public String importXls() throws FileNotFoundException, IOException{
 +		//创建集合存储region对象
 +		List<Region> regionList = new ArrayList<Region>();
 +		
 +		//使用POI解析Excel文件
 +		HSSFWorkbook hssfWorkbook = new HSSFWorkbook(new FileInputStream(regionFile));
 +		//根据名称获得第一个sheet
 +		HSSFSheet sheetAt = hssfWorkbook.getSheetAt(0);
 +		//获得每行对象
 +		for(Row row:sheetAt){
 +			//标题行去掉
 +			if(row.getRowNum() == 0){
 +				continue;
 +			}else{
 +				//遍历行内的每个单元格
 +				for(Cell cell:row){
 +					String id = row.getCell(0).getStringCellValue();
 +					String province = row.getCell(1).getStringCellValue();
 +					String city = row.getCell(2).getStringCellValue();
 +					String district = row.getCell(3).getStringCellValue();
 +					String postcode = row.getCell(4).getStringCellValue();
 +					//包装一个区域对象
 +					Region region = new Region(id, province, city, district, postcode, null, null, null);
 +					regionList.add(region);
 +				}
 +			}
 +		}
 +		//批量保存，不要频繁地开事务
 +		regionService.saveBatch(regionList);
 +		
  		return "toRegion";
  	}

2、RegionServiceImp

@Service
 +public class RegionServiceImp implements RegionService {
 +	@Autowired
 +	private RegionDao regionDao;
 +	/**
 +	 * 批量保存Region对象
 +	 */
 +	@Override
 +	public void saveBatch(List<Region> regionList) {
 +		for(Region region:regionList){
 +			regionDao.saveOrUpdate(region);
 +		}
 +
 +	}
 +
 +}

3、Region.jsp页面相关(OCUpload的使用)

//导入数据表格
 +		$("#button-import").upload({
 +			action:'${pageContext.request.contextPath}/regionAction_importXls.action',
 +			name:'regionFile'
 +		});
