```java
@SpringBootApplication
@Service
@EnableDubbo
public class ConsumerApplication {
@DubboReference
private DemoService demoService;
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(ConsumerApplication.class, args);
ConsumerApplication application = context.getBean(ConsumerApplication.class);
UserSpecifiedAddressUtil.setAddress(new Address("127.0.0.1", 20882, true));
