Java Spring Boot 中使用 @Service 和 @Transactional 注解

@Service @Transactional public class CovidService implements ICovidService { @Resource private CovidMapper covidMapper;

//其他方法省略

}

中文翻译内容：@Service @Transactional public class CovidService implements ICovidService { @Resource private CovidMapper covidMapper;

//其他方法省略

}
