**控制器代码：**

package com.Keafmd.controller;
    
    import com.Keafmd.domain.Account;
    import com.Keafmd.domain.User;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import javax.servlet.ServletContext;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpSession;
    
    /** * Keafmd * * @ClassName: ParamController * @Description: * @author: 牛哄哄的柯南 * @date: 2021-01-24 15:57 */
    
    @Controller
    @RequestMapping("/param")
    public class ParamController { 
    
        /** * 原生的API * @return */
        @RequestMapping("/testServlet")
        public String testParam(HttpServletRequest request, HttpServletResponse response){ 
    
            System.out.println("执行了testServlet");
            System.out.println("request："+request);
    
            HttpSession session =request.getSession();
            System.out.println("session："+session);
    
            ServletContext servletContext = session.getServletContext();
            System.out.println("servletContext："+servletContext);
    
            System.out.println("response："+response);
    
            return "success";
        }
    }

**jsp代码：**

<%--
      Created by IntelliJ IDEA.
      User: keafmd
      Date: 2021/1/24
      Time: 15:55
      To change this template use File | Settings | File Templates.
    --%>
    <%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>请求参数绑定</title>
    </head>
    <body>
    
    <a href="param/testServlet">servlet原生的API</a>
    
    </body>
    </html>

**运行结果：**

执行了testServlet
    request：org.apache.catalina.connector.RequestFacade@49c42855
    session：org.apache.catalina.session.StandardSessionFacade@d52f38e
    servletContext：org.apache.catalina.core.ApplicationContextFacade@74dcdc30
    response：org.apache.catalina.connector.ResponseFacade@395b82b4
