借助 org.springframework.ui.Model 對象或 Map 對象將信息傳到 springmvc 的頁面中
需要：jstl 支持 和 EL 表達式
1.maven 添加依賴：

/** **/@Controller@RequestMapping("/hello")public class HelloController { /** * 請求地址：項目名/hello/userinfo * @return */ @RequestMapping("userinfo") public String userinfo(org.springframework.ui.Model model,Map<String, Object> map){ //傳遞單個對象 UserInfoModel info = new UserInfoModel("張三",99,"男"); model.addAttribute("info",info); List<UserInfoModel> list = new ArrayList<UserInfoModel>(); list.add(new UserInfoModel("李四",20,"男")); list.add(new UserInfoModel("王五",21,"女")); list.add(new UserInfoModel("趙六",22,"男")); //傳遞多個對象 map.put("user_list", list); return "hello/userinfo"; //servlet.xml 中定義的 前綴（prefix）+返回值+后綴（suffix）拼接的物理地址 }} |
