springmvc中进行数据保存以及日期参数的保存过程

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";
  }
