Model和ModelAndView的使用

Model：

public String index(Model model){ model.addAttribute("msg","你好，世界！"); List<String> list = new ArrayList<>(); list.add("学习"); list.add("在学习"); list.add("在学习吗？"); list.add("真的在学习吗？"); model.addAttribute("list",list); model.addAttribute("user",new User("admin","123456",18)); return "index"; }

ModelAndView：

public ModelAndView index(){ ModelAndView mv = new ModelAndView(); mv.addObject("msg","<strong>你好，世界！</strong>"); mv.addObject("msg2","你好，世界!"); List<String> list = new ArrayList<>(); list.add("学习"); list.add("在学习"); list.add("在学习吗？"); list.add("真的在学习吗？"); mv.addObject("list",list); mv.addObject("user",new User("admin","123456",18)); mv.setViewName("index"); return mv; }
