ApplicationListener

利用容器机制获取容器内的bean

@Configuration
public class ContextRefreshedListener implements ApplicationListener<ContextRefreshedEvent> {  

    @Override  
    public void onApplicationEvent(ContextRefreshedEvent event) {  
        // Spring根容器  
        if(event.getApplicationContext().getParent()==null){  
            Map<String,Object> beans = event.getApplicationContext().getBeansWithAnnotation(PermissionFilter.class);    
           System.err.println("=====ContextRefreshedEvent====="+event.getSource().getClass().getName());  
        }  
    }  
}
