service层

@Service
public class AppConfigService extends BaseService<AppConfig>{

    @Autowired
    private AppConfigMapper appConfigMapper;

    @Transactional(readOnly = false, propagation = Propagation.REQUIRED,rollbackFor = Exception.class)
    public void test() {

        AppConfig appConfig = new AppConfig();
        appConfig.setUpBaseId(AppUtil.uuid());
        AppConfig appConfig1 = new AppConfig();
        appConfig1.setUpBaseId(AppUtil.uuid());
        Integer integer = this.saveSelect(appConfig);
        Integer integer1 =this.saveSelect(appConfig1);
        Integer num=integer + integer1;
        if (num==2){
            System.out.println(1);
            throw new  RuntimeException("出现异常了");
        }else{
        }
    }
}

抛出异常事物回滚
