全自动用kindeditor文本编辑器实现后台产品描述图片的增删改(投点分给 thank you)
详细分析在代码上有。。有疑问、问题的可以跟贴问。。。。public class ProductAction extends BaseAction {// 添加商品public String addproduct() throws Exception {// TODO Auto-generated method stubProduct p = new Product(name.trim(), brane, price, marketprice, weight,size, style00, material, colordesc, situation, big, style01,logo, age, struct, element, desc, total);this.adminService.saveOrUpdate(p);File dir = new File(ServletActionContext.getRequest().getRealPath("/productimg"));if (!dir.exists()) {dir.mkdir();}File dst = null;boolean b = false;// 形象照if (img != null) {dst = new File(dir.getAbsolutePath() + File.separator + p.getId()+ ".jpg");// 图像缩咯if ("0".equals(this.model)) {b = this.resize_image(img, dst, 178, 178);} else {b = this.resize_image(img, dst, 180, 300);}if (b)p.setImg(dst.getName());}// 产口图片String temp = "";if (productimg != null) {for (int i = 0;
