@Component
public class TestApplicationListener implements ApplicationListener<ContextRefreshedEvent>{
@Override
public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
System.out.println(contextRefreshedEvent);
System.out.println("TestApplicationListener............................");
}
}
ContextRefreshedEvent 類型會觸發好幾次。
可以使用ApplicationReadyEvent只會觸發一次。
