代码：

package org.example.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.servlet.http.Cookie;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    @RestController
    public class ResponseParamController
    {
    
    
        @RequestMapping(value = "/responseTest1")                     //获取请求行数据
        public void test1(HttpServletRequest request,HttpServletResponse response)
        {
    
            response.setStatus(302);
            response.setHeader("location","/test1");
    
    
        }
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
    
        @RequestMapping(value = "/responseTest15")
        public String test15(HttpServletResponse response)
        {
            response.setHeader("content-type", "text/html;charset=UTF-8");   //告知浏览器使用什么码表
    
            //告知客户端不缓存
            response.setHeader("pragma", "no-cache");
            response.setHeader("cache-control", "no-cache");
            response.setDateHeader("expires", 0);
    
            //添加Cookie
            response.addCookie(new Cookie("cook-001-name" ,"cookie-001-value"));
            response.addCookie(new Cookie("cook-002-name" ,"cookie-002-value"));
    
            response.setStatus(404);  //我们将状态设置成404
            return "test2";
        }
    
    
    
    }

    public class ResponseParamController
    {
    
    
        @RequestMapping(value = "/responseTest1")                     //获取请求行数据
        public void test1(HttpServletRequest request,HttpServletResponse response) throws IOException {
    
    //        response.setStatus(302);
    //        response.setHeader("location","/test1");
    
            response.sendRedirect("/test1");
    
        }
