springmvc中进行数据保存以及日期参数的保存

1.在Controller类中接受传入的日期类型的参数时

<form action="user/todate.do" method="post">
        日期：<input type="text" name="date"/><br />
            <input type="submit" value="查看" />
    </form>

    @RequestMapping("todate.do")
    public String todate(Date date) {
        System.out.println(date);
        return "list";
    }
    

    @InitBinder
    public void initBinder(ServletRequestDataBinder binder){
        //只要网页中传来的数据格式为yyyy-MM-dd 就会转化为Date类型
        binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"),
                true));
    }
    

2.当要传入多个参数时

<form action="user/list2.do" method="post">
        姓名：<input type="text" name="uname"/><br>
        密码：<input type="text" name="password"/><br>
        性别：<input type="text" name="sex"/><br>
        年龄：<input type="text" name="age"/><br>
        地址：<input type="text" name="address"/><br>
        生日：<input type="date" name="birth"><br>
        <input type="submit" value="提交">
    </form>

    @RequestMapping("list2.do")
    public String list2(Users users ) {
        System.out.println(users);
        return "list";
    }

 @InitBinder
    public void initBinder(ServletRequestDataBinder binder){
        //只要网页中传来的数据格式为yyyy-MM-dd 就会转化为Date类型
        binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"),
                true));
    }

　Controller数据保存

　　保存至request里

　　(1)ModelAndView

@RequestMapping("aaa.do")
    public ModelAndView index() {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("index");
        mv.addObject("name","张三");
        return mv;
    }

　(2)Model

@RequestMapping("aaa.do")
    public String index(Model model) {
        model.addAttribute("name", "李四");
        return "index";
    }

　(3)map

@RequestMapping("aaa.do")
    public String index(Map<String, Object> map) {
    map.put("name", "222");
        return "index";
    }

　(4)request

@RequestMapping("list.do")
    public String list(HttpServletRequest request) {
        request.setAttribute("name","wang");
        return "index2";
    }

　　保存至session里

　　

    @RequestMapping("list.do")
    public String list(HttpSession session) {
        session.setAttribute("name","wang");
        return "index2";
    }

　　保存至application里

@RequestMapping("list.do")
    public String list(HttpSession session) {
        session.getServletContext().setAttribute("name","wang");
        return "index2";
    }
