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";
    }



}

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

方法2：

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;
import java.io.IOException;

@RestController
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");

    }


















    @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";
    }



}
