使用表单提交并提交页面上传图面
话不多说，直接上代码
/**
* 增加商品
*/
else if("add".equals(action)){
Good good1=new Good();
//接收增加的商品信息，并调用后台方法，将商品信息插入数据库
String uploadFileName = "";
String fieldName = "";
//good=new Good();
//解析请求之前先判断请求类型是否为文件上传类型/
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
//指定上传位置
String uploadFilePath = request.getSession().getServletContext().getRealPath("GoodsImage/");
File saveDir = new File(uploadFilePath);
//如果目录不存在，就创建目录
if(!saveDir.exists()){
saveDir.mkdir();
}
if(isMultipart){
//创建文件上传核心类
FileItemFactory factory = new DiskFileItemFactory(); // 实例化一个硬盘文件工厂,用来配置上传组件ServletFileUpload
ServletFileUpload upload = new ServletFileUpload(factory); // 用以上工厂实例化上传组件
try{
//处理表单请求
List<FileItem> items = upload.parseRequest(request);
Iterator<FileItem> iter = items.iterator();
while(iter.hasNext()){
FileItem item = (FileItem)iter.next();
if(item.isFormField()){// 如果是普通表单控件
fieldName = item.getFieldName();// 获得该字段名称
if(fieldName.equals("goodsName")){
good1.setGoodsName(item.getString("UTF-8"));//获得该字段值
}else if(fieldName.equals("goodsSmalId")){ //goodsSmalld是前端JSP页面传过来的参数，下面的都是
good1.setGoodsSmalId(Integer.parseInt(item.getString("UTF-8")));
}else if(fieldName.equals("goodsMoney")){
good1.setGoodsMoney(Double.parseDouble(item.getString("UTF-8")));
