java 数据设置和显示

1. 首先设置ModelAndView 的值

    @Override
    public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
 
        ModelAndView mv = new ModelAndView(view);
 
        mv.addObject("name", "moon");
        return mv;
    }

2. 然后在View中获取并设置

<%
 
String get_hello = request.getAttribute("name").toString();
 
response.getWriter().write(get_hello);
 
%>

2.2. 方式二 宏
