Every bean/class instance created twice in spring boot application-CodePudding

I'm using java based configuration, using only @Component and @Scheduler Annotation in my other classes, but I don't know why all classes in class path loaded twice. How to prevent this and how to debug it? problem : All my scheduled methods are running twice in scheduled interval. @Scheduled(cron = "0 0/5 * * * ?")

    @EnableScheduling
    @SpringBootApplication
    @ComponentScan(basePackages = "com.example")
    public class Dashboard implements CommandLineRunner{
    
    
        @Autowired
        private ApplicationContext appContext;
    
        @Autowired
        private EventBus eventBus;
    
        @Auditable(eventProvider = EventProvider.class)
        @PostConstruct
        public void startupApplication() {
            try {
                EventProvider provider = appContext.getBean(EventProvider.class);
                AuditRequestContext requestContext = new AuditRequestContext(null, null, null, null);
                Event aaaEvent = provider.getEvent(requestContext);
                eventBus.post(aaaEvent);
            } catch (Exception e) {
                System.out.println("Error getting bean for the class: " , e);
            }
        }
    
        public static void main(String[] args) {
            SpringApplication.run(Dashboard.class, args);
        }
    
        @Override
        public void run(String... args) throws Exception {
           String [] beans = appContext.getBeanDefinitionNames();
           Arrays.sort(beans);
           for(String bean : beans) {
               logger.info("bean :: "   bean);
           }  
        }
    
    }

Log printed: every bean loaded twice (All my scheduled methods are running twice)

How to resolve this?

Added Log4j configuration.

CodePudding user response：

You want to set additivity to false for your com.example logger. @AndyWilkinson is correct you're duplicating your logs, not your beans.
