SpringMVC参数返回给页面

springMVC将后台参数返回给前台页面

方法一：利用ModelAndView返回值

@RequestMapping("/returnPage.do")
    public ModelAndView returnPage(){
        Person person = new Person();
        person.setId(1);
        person.setName("zs");
        person.setGender(2);
        person.setAge(25);
        person.setBirthday(new Date());
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("person", person);
        return new ModelAndView("returnPage",map);
    }

方法二：利用方法中的参数

@RequestMapping("/returnPage1.do")
    public String returnPage1(Map<String,Object> map){
        Person person = new Person();
        person.setId(1);
        person.setName("zs");
        person.setGender(2);
        person.setAge(25);
        person.setBirthday(new Date());
        map.put("person", person);
        return "returnPage";
    }

方法三：利用Model

@RequestMapping("/returnPage2")
    public String returnPage2(Model model){
        Person person = new Person();
        person.setId(1);
        person.setName("zs");
        person.setGender(2);
        person.setAge(25);
        person.setBirthday(new Date());
        model.addAttribute("person", person);
        return "returnPage";
    }

前台页面显示内容

 ${person.id }<br>
    ${person.name }<br>
    ${person.gender }<br>
    ${person.age }<br>
    ${person.birthday }<br>
    <fmt:formatDate value="${person.birthday }" pattern="yyyy-MM-dd"/>
