1.提交方式必须是post
2.表单中的上传项必须有name属性
3.表单的 enctype 属性必须是multipart/form-data

Action中：

    //文件上传需要的参数    private File upload;//上传的文件    private String uploadFileName; //接收文件名    private String uploadContextType;//接收文件类型    public void setUpload(File upload) {        this.upload = upload;    }    public void setUploadFileName(String uploadFileName) {        this.uploadFileName = uploadFileName;    }    public void setUploadContextType(String uploadContextType) {        this.uploadContextType = uploadContextType;    }    public void setCategorySecondService(CategorySecondService categorySecondService) {        this.categorySecondService = categorySecondService;    }    public String save() {        product.setPdate(new Date());        if(upload != null) {            //获得文件上传的磁盘绝对路劲            String realPath =  ServletActionContext.getServletContext().getRealPath("/products");            //创建一个文件            File disFile = new File(realPath+"//"+uploadFileName);            //文件上传            try {                FileUtils.copyFile(upload, disFile);            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }            product.setImage("products/"+uploadFileName);        }        //将数据保存到数据库        productService.save(product);        return "savesuccess";    }

jsp代码：

<tr>    <td  width="18%" align="center" class="ta_01" bgColor="#ffffff">    商品图片：    </td>    <td class="ta_01" bgColor="#ffffff">                    <input type="file" name="upload"/>    </td></tr>
