頁面封裝好Map結構後，頁面使用${} 就可以獲取到數值
Controller
@Controller @RequestMapping("/index.do") public class IndexController { @RequestMapping(params = "add") public ModelAndView add(@RequestParam("name") String name, @RequestParam("age") String age) { // Map<String, Object> params = new HashMap<String, Object>(); // params.put("sex", "man"); ModelMap params = new ModelMap(); params.addAttribute("name", name); params.addAttribute("age", age); ModelAndView modelAndView = new ModelAndView("success", params); return modelAndView; } }
頁面jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here1</title> </head> <body>${name} </body> </html>
結果：
注意：如果返回的是list 頁面可以用C標籤foreach迴圈獲取
