spring 或者spring boot 调整bean加载顺序的方式

@Configuration
@Order(1)
public class ConfigA {
    @Bean
    public ServiceA serviceA(){
        System.out.println("ConfigA 执行");
        return new ServiceA();
    }
}
@Configuration
@Order(2)
public class ConfigB {
    @Bean
    public ServiceB serviceB(){
        System.out.println("ConfigB 执行");
        return new ServiceB();
    }
}

@Configuration
public class Config {
    @Bean
    @Order(1)
    public CListener bListener(){
        return new CListener();
    }

     @Bean
     @Order(2)
    public DListener dListener(){
        return new DListener();
    }
}

public class AListener implements ApplicationListener<ContextRefreshedEvent>, Ordered {

    private CuratorManagerComponent curatorManagerComponent;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {

        logger.info("AListener 执行了。");

    }
}

    @Override
