每日总结 4.28

今天进行了一天的课程，进行了较少的代码编写。

String time=request.getParameter("time");
            d.buhuo(name,sum,mphone);
            d.gx(mer, time, mphone, name);
            response.setContentType("text/html;charset=utf-8");
            PrintWriter out = response.getWriter();
            out.println("<script language=javascript>alert('补货成功');window.history.go(-1);location.href=document.referrer</script>");
