后端添加如下代码

package com.example.demo;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;

/**
 * 请求的基本过滤器 预处理请求头
 */
@WebFilter(urlPatterns = {"/*"}, filterName = "tokenAuthorFilter")
public class TokenAuthorFilter implements Filter {

    private static Logger LOG = LoggerFactory.getLogger(TokenAuthorFilter.class);

    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest req = (HttpServletRequest) request;
        HttpServletResponse rep = (HttpServletResponse) response;
        HttpSession session = req.getSession();

        rep.setHeader("Access-Control-Allow-Origin",  req.getHeader("Origin"));
        rep.setHeader("Access-Control-Allow-Credentials", "true");
        rep.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE, PATCH");
        rep.setHeader("Access-Control-Max-Age", "0");
        rep.setHeader("Access-Control-Allow-Headers", "token, Origin, X-Requested-With, Content-Type, Accept");

        //谷歌浏览器需要以下设置才能保证下一次请求会携带cookie
        if(rep.getHeader("Set-Cookie") != null){
            rep.setHeader("Set-Cookie",rep.getHeader("Set-Cookie")+"; Secure=true; Samesite=none");
        }
        chain.doFilter(req, rep);

    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}

　　

　前端添加配置

axios.defaults.withCredentials=true;
