三种springboot启动时加载方式

一个注解，两个接口，常用于数据预热：

`@PostConstruct`

`implements CommandLineRunner`

`implements ApplicationRunner`

@Slf4j
@EnableAsync
@SpringBootApplication
public class ApiApplication extends SpringBootServletInitializer implements CommandLineRunner {

@Autowired
private RiskLevelService riskLevelService;

public static void main(String[] args) {
	SpringApplication.run(ApiApplication.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
	return application.sources(ApiApplication.class);
}

//implements CommandLineRunner
@Override
public void run(String... args) throws Exception {
	log.info("假装在预热");
}

//@PostConstruct
//public void preLoadCache() {
//	log.info("假装在预热");
//}

//implements ApplicationRunner
//@Override
//public void run(ApplicationArguments args) throws Exception {
//	log.info("假装在预热");
//}

}
