springmvc 向页面传值

1、自动注入Model参数，对model变量添加属性。

@Controller
@RequestMapping("user")
public class UserController {
    
    @RequestMapping(method=RequestMethod.GET)
    public String allUser(Model model){
        List<String> list = new ArrayList<String>();
        list.add("zhangsan");
        list.add("lisi");
        model.addAttribute("list", list);
        return "list";
    }
}

在页面中读出

 
  <body>
    <ul>
        <c:forEach items="${list}" var="item">
            <li>${item}</li>
        </c:forEach>
        
    </ul>
  </body>

2、新建一个ModelAndView

    
    @RequestMapping(method=RequestMethod.GET)
    public ModelAndView allUsers(){
        ModelAndView mav = new ModelAndView();
        mav.setViewName("list");
        List<String> list = new ArrayList<String>();
        list.add("zhangsan");
        list.add("lisi");
        mav.addObject("list", list);
        return mav;
    }
