c.UploadForm
View Code
1 package cnblogs.xiaoqiu.web.action.formbean; 2 3 import org.apache.struts.upload.FormFile; 4 5 public class UploadForm extends BaseForm { 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; 15 } 16 17 public void setDeleteIds(int[] deleteIds) { 18 this.deleteIds = deleteIds; 19 } 20 21 public int getId() { 22 return id; 23 } 24 25 public void setId(int id) { 26 this.id = id; 27 } 28 29 public FormFile getUploadFile() { 30 return uploadFile; 31 } 32 33 public void setUploadFile(FormFile uploadFile) { 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
View Code
