1.首先引入jersey jar包
2.在配置文件中，配置允许上传图片
3.修改增加商品页面
<%@ page language="java" import="java.util." pageEncoding="UTF-8"%>
<%@ include file="/back_page/head.jsp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ""
[/span>html xmlns=""
[/span>head
[/span>title
[/span>script type="text/javascript"
function uploadPic() {
var options={
url:"/cn/upload/uploadPic.do", 访问保存图片的controller层的方法
dataType:"json",
type:"post",
success:function(data){
//回调2个路径
//url 绝对路径，用于在页面上显示图片
//path 相对路径，保存在数据库中
$("#allImgUrl").attr("src",data.url); 显示图片
$("#path").val(data.path)
}
}
$("#jvForm").ajaxSubmit(options);
}
