Springboot启动后执行方法小结

@Component
public class StartInit {
//
//    @Autowired   可以注入bean
//    ISysUserService userService;

    @PostConstruct
    public void init() throws InterruptedException {
        Thread.sleep(10*1000);//这里如果方法执行过长会导致项目一直无法提供服务
        System.out.println(123456);
    }
}

@Component
public class CommandLineRunnerImpl implements CommandLineRunner {
    @Override
    public void run(String... args) throws Exception {
        System.out.println(Arrays.toString(args));
    }
}

@Component
public class ApplicationRunnerImpl implements ApplicationRunner {
    @Override
    public void run(ApplicationArguments args) throws Exception {
        Set<String> optionNames = args.getOptionNames();
        for (String optionName : optionNames) {
            List<String> values = args.getOptionValues(optionName);
            System.out.println(values.toString());
        }
    }
}

@Component
public class ApplicationListenerImpl implements ApplicationListener<ApplicationStartedEvent> {
    @Override
    public void onApplicationEvent(ApplicationStartedEvent event) {
        System.out.println("listener");
    }
}
