啟動(@SpringBootApplication)

/*SpringBoot項目的Bean裝配默認(rèn)規(guī)則是根據(jù)Application類所在的包位置從上往下掃描！ “Application類”是指SpringBoot項目入口類。這個類的位置很關(guān)鍵*/
@SpringBootApplication
public class SpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootWebDemoApplication.class, args);
    }
}

事務(wù)(@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);
    }
}
