解决办法

@SpringBootApplication
public class ConsumerApplication {

    public static void main(String[] args) {
        if (AuthConfigFactory.getFactory() == null) {
            AuthConfigFactory.setFactory(new AuthConfigFactoryImpl());
        }
        SpringApplication.run(ConsumerApplication.class, args);
    }
}
