 6     private static final long serialVersionUID = 1724297881513682925L;
 7     
 8     private FormFile uploadFile;
 9     private int id;
10     private int[] deleteIds;
11     
12     
13     public int[] getDeleteIds() {
14         return deleteIds;

34         this.uploadFile = uploadFile;
35     }
36     
37 }

2.完成文件列表的全选功能(添加复选框，编写javascript函数,formbean中添加ids[])
3.完成上传文件的多选删除功能

View Code

 1 public ActionForward delete(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)
 2     throws Exception {
 3         UploadForm uploadForm = (UploadForm)form;
 4         int[] ids = uploadForm.getDeleteIds();
 5         for(int i=0;i<ids.length;i++){
 6             UploadFile uploadFile = uploadService.find(UploadFile.class, ids[i]);
 7             String filePath = uploadFile.getFilePath();
 8             if(filePath!=null){
 9                 File file = new File(request.getSession().getServletContext().getRealPath(filePath));
10                 file.delete();
11                 uploadService.delete(UploadFile.class, uploadFile.getId());
12                 request.setAttribute("message", "删除成功");
13             }
14             else {
15                 request.setAttribute("message", "删除失败");
16             }
17         }
18         request.setAttribute("jump", PropertiesTool.getValue("control.upload.list"));
19         return mapping.findForward("message");
20     }

4.产品管理模块的详细分析与设计
a.产品的相关操作:分页显示，添加，修改，查询，上架/下架
b.产品的相关字段

5.创建产品实体对象
