org.springframework.beans.factory.NoSuchBeanDefinitionException：没有名为'eventpublisher'的bean可用

我有一个Spring Boot应用程序。我用@Component注解标注了一个项目的类。现在在我的主类中，当我试图获取类的bean时，我得到一个无法找到该bean的异常。org.springframework.beans.factory.NoSuchBeanDefinitionException：没有名为'eventpublisher'的bean可用

Exception in thread "main" [2m2017-05-08 09:53:55.303[0;39m [32m INFO[0;39m [35m9112[0;39m [2m---[0;39m [2m[  Thread-2][0;39m [36ms.c.a.AnnotationConfigApplicationContext[0;39m [2m:[0;39m Closing org.spring[email protected]4df828d7: startup date [Mon May 08 09:53:54 EDT 2017]; root of context hierarchy

    at com.fannie.SpringEventGenerationJBsApplication.main(SpringEventGenerationJBsApplication.java:17)

我的类被注释为组分以下

@Component 
public class EventPublisher implements ApplicationEventPublisherAware { 
    @Autowired 
    private ApplicationEventPublisher publisher; 

    public void eventpublishers() { 
     ActualEvent actualEvent = new ActualEvent(this); 
     System.out.println(actualEvent); 
     publisher.publishEvent(actualEvent); 
    } 

    @Override 
    public void setApplicationEventPublisher(ApplicationEventPublisher publisher) { 
     this.publisher = publisher; 
    } 
}

@SpringBootApplication 
@ComponentScan(basePackages = {"com.fannie"}) 
public class SpringEventGenerationJBsApplication { 

    public static void main(String[] args) { 
     ApplicationContext context = SpringApplication.run(SpringEventGenerationJBsApplication.class, args); 

     EventPublisher ep = (EventPublisher) context.getBean("eventpublisher"); 

     ep.eventpublishers(); 
    }

Bean名称是从小写的第一个字符的类名生成的......所以'EventPublisher'将成为'eventPublisher'而不是'eventpublisher'。 –

谢谢你的作品。非常感谢。 – DP3

@ M.Deinum也许你应该添加这个答案。你刚刚解决了我的问题，如果我能，至少，upvote你会很棒。 –

作为记录here

弹簧产生用于未命名的组件bean的名字，按照上述规则：基本上，服用简单的类名和具有由组件的扫描所得到的bean名称检测将是eventPublisher一类EventPublisher时，转动其初始字符小写

所以。
