		CorsConfiguration corsConfiguration = new CorsConfiguration();
		// 1.1 允许的域名，不要写“*”,否则cookie就无法使用
		corsConfiguration.addAllowedOrigin("http://www.orderfood.com:8080");
		// 1.2 是否发送Cookie信息
		corsConfiguration.setAllowCredentials(true);
		// 1.3 允许的请求方式
		corsConfiguration.addAllowedMethod("OPTIONS");

		corsConfiguration.addAllowedMethod("GET");
		corsConfiguration.addAllowedMethod("PUT");
		corsConfiguration.addAllowedMethod("POST");

		// 1.4 允许的头信息
		corsConfiguration.addAllowedHeader("*");
		// 1.5 有效时长（在有效时长内，如果再次发送特殊请求，不会发送预请求）
		corsConfiguration.setMaxAge(3600L);
		// 2. 添加映射路径，拦截一切请求
		UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
		urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
		// 3. 返回CorsFilter
		return new CorsFilter(urlBasedCorsConfigurationSource);
