SpringBoot项目预加载数据——ApplicationRunner、CommandLineRunner、InitializingBean 、@PostConstruct区别

@Component
@Order(3)
public class App01 implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("App01_执行了……@Order(3)");
    }

}

@Component
@Order(2)
public class App02 implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("App02_执行了……@Order(2)");
    }
    
}

@Component
@Order(1)
public class Com01 implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        System.out.println("Com01_执行了……@Order(1)");
    }

}

@Component
@Order(0)
public class Com02 implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        System.out.println("Com02_执行了……@Order(0)");
    }

}
