        //1、添加CORS配置信息
        CorsConfiguration config = new CorsConfiguration();
        //2、允许写的域，不要写*，否则cookie就无法使用了
        config.addAllowedOrigin("http://manage.leyou.com");

        //3、是否发送cookie信息
        config.setAllowCredentials(true);
        //4、允许的请求方式
        config.addAllowedMethod("OPTIONS");

        config.addAllowedHeader("*");
        //6、有效时长
        config.setMaxAge(3600L);
        //7、添加映射路径,拦截一切请求

        //8、返回新的CorsFilter
