启动(@SpringBootApplication)

/*SpringBoot项目的Bean装配默认规则是根据Application类所在的包位置从上往下扫描！ “Application类”是指SpringBoot项目入口类。这个类的位置很关键*/
@SpringBootApplication
public class SpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootWebDemoApplication.class, args);
    }
}

事务(@EnableTransactionManagement)

@SpringBootApplication
@EnableTransactionManagement
public class SpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootWebDemoApplication.class, args);
    }
}

@Transactional
public interface BatchUserService {
    ResponseObject batchRegisterLewUser(BatchRegisterReq req);
    ResponseObject batchRegisterLiveUser(BatchRegisterReq req);
}

使用外置tomcat

@SpringBootApplication
@EnableTransactionManagement
public class Application extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
