1.前端配置

 const _axios = axios.create({
                baseURL: 'http://localhost:8080',
                withCredentials: true
            })

前端这里我写成开始写成了127.0.0.1的形式，导致cookie一直不一致，需要改成 http://localhost

2.后端配置

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.*;

@Configuration
@EnableWebMvc
public class WebMvcConfig  implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        // 允许跨域访问的路径
        registry.addMapping("/**")
                // 允许跨域访问的源
                .allowedOrigins("http://localhost:7070")
                // 允许请求方法
                .allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
                // 预检间隔时间
                .maxAge(168000)
                // 允许头部设置
                .allowedHeaders("*")
                // 是否发送cookie
                .allowCredentials(true);

    }
}

后端代码

  @PostMapping("a6set")
    public String a6set(HttpSession session , HttpServletRequest request) {
        System.out.println("=============================");
        System.out.println(session.getId());
        System.out.println(request.getSession().getId());
        session.setAttribute("name", "张三");
        System.out.println("set");
        return "post request";
    }


    @PostMapping("a6get")
    public String a6get(HttpSession session, HttpServletRequest request) {
        System.out.println("=============================");
        System.out.println(session.getId());
        System.out.println(request.getSession().getId());
        Object name = session.getAttribute("name");
        System.out.println("get" + name);
        return "post request";
    }
