你要看一下从后台传送来的数据类型是否是list类型；
你试一下用ArrayList定义。
我后台new的是ArrayList,需要改jsp里面的内容吗?
这句话An error occurred at line: 13 in the jsp file: /index.jsp
goodsVO cannot be resolved to a type
不是说了类型不对吗?后台request.setAttribut() key-value中 value是否是list类型，你用arraylist试一下
是不是你jsp界面接收的类型和你在数据库中定义的类型不同？
List lists = (List) request.getAttribute("lists");
把具体类型加上
需要 把接受过来的list泛型 注意要引入 你所泛型的类到jsp中
