Controller控制层

@Controller // 将当前class作为控制层
public class wedController {
    @Autowired //导入
    private HttpServletRequest request;


    @RequestMapping("/webHome")  // 当前函数的请求映射路径
    public String webHome() {
        Map<String, Object> stu = new HashMap<>();
        stu.put("id", 100012);
        stu.put("name", "tom");
        stu.put("age", 19);
        stu.put("is_Mar", true);
        stu.put("gender", true);

        Map<String, Object> u = new HashMap<>();
        u.put("id", 100013);
        u.put("name", "jreey");
        u.put("age", 25);
        u.put("is_Mar", true);
        u.put("gender", false);

        Map<String, Object> aa = new HashMap<>();
        aa.put("id", 100014);
        aa.put("name", "potty");
        aa.put("age", 28);
        aa.put("is_Mar", false);
        aa.put("gender", true);

        List<Map<String, Object>> sss = new ArrayList<>();
        sss.add(stu);
        sss.add(u);
        sss.add(aa);

        request.setAttribute("sss", sss);
        return ("wedHome.html");
