巴巴运动网学习笔记(76-80)
1.实现修改产品样式的功能
View Code
1 /** 2 * 样式修改 3 */ 4 public ActionForward edit(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) 5 throws Exception { 6 ProductForm productForm = (ProductForm)form; 7 Style style = productStyleService.find(Style.class, productForm.getProductStyleId()); 8 style.setName(productForm.getStyleName()); 9 if(productForm.getImage()!=null&&productForm.getImage().getFileSize()>0){ 10 if(!productForm.isImageTypeValidate(productForm.getImage())){ 11 request.setAttribute("message","图片格式不正确"); 12 request.setAttribute("jump", PropertiesTool.getValue("control.product.style.list")+"?id="+productForm.getId()); 13 return mapping.findForward("message"); 14 } 15 StringBuffer fileDir = new StringBuffer("/file/product/"); 16 StringBuffer sizedFileDir = new StringBuffer("/file/product/"); 17 sizedFileDir.append(style.getProduct().getProductType().getId()+"/"+style.getProduct().getId()+"/sized"); 18 fileDir.append(style.getProduct().getProductType().getId()+"/"+style.getProduct().getId()+"/prototype"); 19 String imageRealDir = request.getSession().getServletContext().getRealPath(fileDir.toString()); 20 String sizedRealDir = request.getSession().getServletContext().getRealPath(sizedFileDir.toString()); 21 File dir = new File(imageRealDir); 22 File sizedDir = new File(sizedRealDir); 23 if(!dir.exists()) dir.mkdirs(); 24 if(!sizedDir.exists()) sizedDir.mkdirs(); 25 StringBuffer imageName = new StringBuffer(UUID.randomUUID().toString()); 26 String fileExt = productForm.getImage().getFileName().substring(productForm.getImage().getFileName().lastIndexOf('.')); 27 imageName.append(fileExt); 28 FileOutputStream outputStream = new FileOutputStream(new File(imageRealDir,imageName.toString())); 29 outputStream.write(productForm.getImage().getFileData()); 30 outputStream.close(); 31 ImageSizer.resize(new File(dir,imageName.toString()), new File(sizedDir,imageName.toString()), 140, fileExt.substring(1)); 32 style.setImagePath(fileDir.toString()+"/"+imageName); 33 } 34 productStyleService.update(style); 35 request.setAttribute("message", "修改成功!"); 36 request.setAttribute("jump", PropertiesTool.getValue("control.product.style.list")+"?id="+style.getProduct().getId()); 37 return mapping.findForward("message"); 38 }
2.实现产品样式的上下架功能
a.业务逻辑层代码
View Code
1 package cnblogs.xiaoqiu.service.product.impl; 2 3 import javax.persistence.Query; 4 5 import org.springframework.stereotype.Service; 6 import cnblogs.xiaoqiu.service.base.DAOSupport; 7 import cnblogs.xiaoqiu.service.product.ProductStyleService; 8 @Service 9 public class ProductStyleServiceImpl extends DAOSupport implements ProductStyleService { 10 11 public void setVisible(int[] productStyleIds, boolean state) { 12 if(productStyleIds!=null&&productStyleIds.length>0){ 13 StringBuffer jpql = new StringBuffer(""); 14 for(int i=0;i<productStyleIds.length;i++){ 15 jpql.append("?"+(i+2)+","); 16 } 17 jpql.deleteCharAt(jpql.length()-1); 18 Query query = entityManager.createQuery("update Style p set p.visible = ?1 where p.id in("+jpql+")"); 19 query.setParameter(1, state); 20 for(int i=0;i<productStyleIds.length;i++){ 21 query.setParameter(i+2, productStyleIds[i]); 22 } 23 query.executeUpdate(); 24 } 25 } 26 27 }
b.控制层代码
View Code
1 /** 2 * 设置某种样式的产品上架 3 */ 4 public ActionForward toShelf(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) 5 throws Exception { 6 ProductForm productForm = (ProductForm)form; 7 productStyleService.setVisible(productForm.getStyleIds(), true); 8 request.setAttribute("message", "设置成功!"); 9 request.setAttribute("jump", PropertiesTool.getValue("control.product.style.list")+"?id="+productForm.getId()); 10 return mapping.findForward("message"); 11 } 12 13 /** 14 * 设置某种样式的产品下架 15 */ 16 public ActionForward offShelf(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) 17 throws Exception { 18 ProductForm productForm = (ProductForm)form; 19 productStyleService.setVisible(productForm.getStyleIds(), false); 20 request.setAttribute("message", "设置成功!"); 21 request.setAttribute("jump", PropertiesTool.getValue("control.product.style.list")+"?id="+productForm.getId()); 22 return mapping.findForward("message"); 23 }
3.图片压缩处理的介绍
4.在产品图片管理中集成图片压缩(将图片压缩成指定大小)
View Code
1 if(productForm.getImage()!=null&&productForm.getImage().getFileSize()>0){ 2 if(!productForm.isImageTypeValidate(productForm.getImage())){ 3 request.setAttribute("message","图片格式不正确"); 4 request.setAttribute("jump", PropertiesTool.getValue("control.product.style.list")+"?id="+productForm.getId()); 5 return mapping.findForward("message"); 6 } 7 StringBuffer fileDir = new StringBuffer("/file/product/"); 8 StringBuffer sizedFileDir = new StringBuffer("/file/product/"); 9 sizedFileDir.append(style.getProduct().getProductType().getId()+"/"+style.getProduct().getId()+"/sized"); 10 fileDir.append(style.getProduct().getProductType().getId()+"/"+style.getProduct().getId()+"/prototype"); 11 String imageRealDir = request.getSession().getServletContext().getRealPath(fileDir.toString()); 12 String sizedRealDir = request.getSession().getServletContext().getRealPath(sizedFileDir.toString()); 13 File dir = new File(imageRealDir); 14 File sizedDir = new File(sizedRealDir); 15 if(!dir.exists()) dir.mkdirs(); 16 if(!sizedDir.exists()) sizedDir.mkdirs(); 17 StringBuffer imageName = new StringBuffer(UUID.randomUUID().toString()); 18 String fileExt = productForm.getImage().getFileName().substring(productForm.getImage().getFileName().lastIndexOf('.')); 19 imageName.append(fileExt); 20 FileOutputStream outputStream = new FileOutputStream(new File(imageRealDir,imageName.toString())); 21 outputStream.write(productForm.getImage().getFileData()); 22 outputStream.close(); 23 ImageSizer.resize(new File(dir,imageName.toString()), new File(sizedDir,imageName.toString()), 140, fileExt.substring(1)); 24 style.setImagePath(fileDir.toString()+"/"+imageName); 25 }
5.前台展示页面的布局与源码分析(将html页面切割成jsp页面，通过包含技术复用头尾)
a.show.jsp
