[SpringBoot2]请求处理_@RequestAttribute

Posted 2022-03-03 唐火

@Controller
public class RequestController 

    @GetMapping("/goto")
    public String gotoPage(HttpServletRequest request)
    
        request.setAttribute("msg","success");
        request.setAttribute("code",200);
        return "forward:/success";
    

    @ResponseBody
    @GetMapping("/success")
    public Map success(@RequestAttribute("msg") String msg, @RequestAttribute("code") Integer code, HttpServletRequest request)
    


        Object msg1 = request.getAttribute("msg");

        Map<String ,Object> map  = new HashMap<>();

        map.put("reqMethod_msg",msg1);

        map.put("annotation_msg",msg);



        return map;
    

可以看到两种方式都可以取到存在域中的值！
