        // 程式啟動入口
        // 啟動嵌入式的 Tomcat 並初始化 Spring 環境及其各 Spring 元件
        ConfigurableApplicationContext run = SpringApplication.run(ClientApplication.class, args);
        CityDubboConsumerService cityService = run.getBean(CityDubboConsumerService.class);
        System.out.println(cityService);
    }
}
