PromotionAction代碼：

@ParentPackage("json-default") @Namespace("/") @Controller @Scope("prototype") public class PromotionAction extends BaseAction<Promotion>{private File titleImgFile;//接收上傳的圖片private String titleImgFileName;//接收上傳圖片的名稱public void setTitleImgFileFileName(String titleImgFileFileName) {this.titleImgFileFileName = titleImgFileFileName;}public void setTitleImgFile(File titleImgFile) {this.titleImgFile = titleImgFile;}@Autowiredprivate PromotionService promotionService;@Action(value="promotion_save",results={@Result(name="success",type="redirect",location="./pages/take_delivery/promotion.html")})public String save() throws IOException{//宣傳圖上傳、在數(shù)據(jù)表保存宣傳圖的路徑String savePath = ServletActionContext.getServletContext().getRealPath("/upload/");String saveUrl = ServletActionContext.getServletContext().getContextPath("/upload/");//生成隨機圖片名UUID uuid = UUID.randomUUID();String ext = titleImgFileFileName.substring(titleImgFileName.lastIndexOf("."));//擴展名String randomFileName = uuid +ext;//圖片名=隨機唯一串+擴展名//保存圖片（絕對路徑保存）File destFile = new File(savePath + "/" + randomFileName);System.out.println(destFile.getAbsolutePath());FileUtils.copyFile(titleImgFile,destFile);//將相對工程web的訪問路徑，保存到model中model.setTitleImg(ServletActionContext.getRequest().getContextPath()+"/upload/"+randomFileName);//調(diào)用業(yè)務(wù)層，完成活動任務(wù)數(shù)據(jù)保存promotionService.save(model);return SUCCESS;}//促銷活動列表分頁查詢@Action(value="promotion_pageQuery",results = {@Result(name="success",type="json")})public String pageQuery(){//構(gòu)造分頁查詢參數(shù)Pageable pageable = new PageRequest(page-1,rows);//調(diào)用業(yè)務(wù)層完成查詢Page<Promotion> pageData = promotionService.findPageData(pageable);//壓入值棧pushPageDataToValueStack(pageData);return SUCCESS;} }

apache.common.io包下有一個FileUtils類，其中有一個copyFile的方法，可以直接將上傳的圖片保存到指定路徑。

public static void copyFile(File srcFile, File destFile) throws IOException {copyFile(srcFile, destFile, true); }

PromotionService接口代碼：

public interface PromotionService {//保存宣傳任務(wù)void save(Promotion promotion);//分頁查詢Page<Promotion> findPageData(Pageable pageable);//根據(jù)page和rows返回分頁數(shù)據(jù)@Path("/pageQuery")@GET@Produces({"application/xml","application/json"})PageBean<Promotion> findPageData(@QueryParam("page") int page,@QueryParam("rows") int rows);//根據(jù)id查詢@Path("/promotion/{id}")@GET@Produces({"application/xml","application/json"})Promotion findById(@PathParam("id") Integer id);//設(shè)置活動過期void updateStatus(Date date); }

PromotionServiceImpl實現(xiàn)類代碼：

@Service @Transactional public class PromotionServiceImpl implements PromotionService {@Autowiredprivate PromotionRepository promotionRepository;@Overridepublic void save(Promotion promotion){promotionRepository.save(promotion);}@Overridepublic Page<Promotion> findPageData(Pageable pageable){return promotionRepository.findAll(pageable);}@Overridepublic PageBean<Promotion> findPageData(int page,int rows){Pageable pageable = new PageRequest(page-1,rows);Pahe<Promotion> pageData = promotionRepository.findAll(pageable);//封裝到Page對象PageBean<Promotion> pageBean = new PageBean<Promotion>();pageBean.setTotalCount(pageData.getTotalElements());pageBean.setPageData(pageData.getContent());return pageBean;}@Overridepublic Promotion findById(Integer id){return promotionRepository.findOne(id);}@Overridepublic void updateStatus(Date date){promotionRepository.updateStatus(date);} }

dao持久層PromotionRepository代碼：

public interface PromotionRepository extends JpaRepository<Promotion,Integer>{@Query("update Promotion set sratus='2' where endDate<? and status='1'>")@Modifyingvoid updateStatus(Date now); }
