        config.addAllowedOrigin("*");
        //设置是否发送cookie信息
        config.setAllowCredentials(true);
        //设置允许请求的方式
        config.addAllowedMethod("*");

        //设置允许的Header
        config.addAllowedHeader("*");

        UrlBasedCorsConfigurationSource corsSource = new UrlBasedCorsConfigurationSource();
        corsSource.registerCorsConfiguration("/**", config);

        //3.返回重新定义好的corsSource
        return new CorsFilter(corsSource);
