java - spring中如何从jsp中调用controller类

Question

我想存储用户的每一个细节，比如用户代理和一些更多的标题和用户最近点击的 url 页面的名称，我已经创建了一个 Controller 类来存储所有细节，我有超过 20 页怎么能当用户点击我的 jsp 页面时从后端调用 HelloController 类，以便我将所有标题、时间和 url 存储在数据库中

    @Controller
    public class HelloController {

        @RequestMapping(value = "/StroreHits")
        public String hello(
                @RequestHeader(value="Accept") String accept,
                @RequestHeader(value="Accept-Language") String acceptLanguage,
                @RequestHeader(value="User-Agent", defaultValue="foo") String userAgent,
                HttpServletResponse response) {

            System.out.println("accept: " + accept);
            System.out.println("acceptLanguage: " + acceptLanguage);
            System.out.println("userAgent: " + userAgent);
          String url_name   = request.getRequestURL().toString() + "?" + request.getQueryString()

         StoreHits sh =  new StoreHits ();
sh.insertValues(accept,acceptLanguage,userAgent,name);
            return null;
        }

    }

suppose you are hitting on some url like exaple.com/index at that time i want to store you every detail in database one way is i write the same code to all controller class getting and storing all headers of user

您需要编写 Spring MVC 拦截器，它会在您发送到 spring Controller 的每个请求之前被调用。
