版本:springboot2.1.1

1.类上添加@Component注解,要执行的方法上添加@PostConstruct

@Slf4j
@Component
public class AutoStart {
    @PostConstruct
    public void init() {
        log.info("启动.................");
    }
}

2.类上添加@Component注解,并实现CommandLineRunner接口重写run方法;run方法即在程序启动后执行

@Slf4j
@Component
public class AutoStart implements CommandLineRunner {
    @Autowired
    private LoadInfo loadInfo;
    @Override
    public void run(String... args) throws Exception {
        log.info("启动.................");
        loadInfo.init();
    }
}
