1.设置ModelAndView对象。根据View和视图解析器跳转到指定页面（视图解析器前缀+viewname+视图解析器后缀）
@Override public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse resp) throws Exception { ModelAndView mv = new ModelAndView(); mv.setViewName("hello"); mv.addObject("msg", "first spring mvc app"); return mv; }
2.通过ServletAPI对象来实现，不需要配置视图解析器
通过HttpServletRequest输出
resp.getWriter().print("Use httpServletAPI");
通过HttpServletRequest实现重定向
@RequestMapping(value = "/hi.do") public void hello(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { resp.sendRedirect("hello.jsp"); }
通过HttpServletRequest实现转发
@RequestMapping(value = "/hi.do") public void hello(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { req.setAttribute("msg", "testRequestDispatcher"); req.getRequestDispatcher("hello.jsp").forward(req, resp); }
3.通过springMVC来实现重定向和转发
转发
@RequestMapping("/hi2")
public String hello2() {
//转发1
//return "index";
//转发2
return "forward:index.jsp";
}
重定向
@RequestMapping("/hi3.do")
public String hello3(ModelMap map) {
map.addAttribute("msg", "helloworld");
return "redirect:index.jsp";
}
