SpringBoot引入监听器

方法一：

实现CommandLineRunner 接口

@Component
@Order(1)
public class AppReadyListener implements CommandLineRunner {
    
    @Override
    public void run(String... args) throws Exception {
        
    }
}

方法二：

实现ApplicationRunner 接口

@Component
@Order(2)
public class FinishListener implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception {

    }
}
