使用SpringBoot将中国地震台网数据保存PostGIS数据库实践

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
 
@Service
public class EarthquakeService {
 
    private final EarthquakeRepository earthquakeRepository;
 
    @Autowired
    public EarthquakeService(EarthquakeRepository earthquakeRepository) {
        this.earthquakeRepository = earthquakeRepository;
    }
 
    @Transactional
    public void saveEarthquakes(List<Earthquake> earthquakes) {
        earthquakeRepository.saveAll(earthquakes);
    }
}

这段代码定义了一个服务层类EarthquakeService，它使用@Autowired注解自动装配EarthquakeRepository。saveEarthquakes方法通过传入的地震列表使用EarthquakeRepository的saveAll方法来保存地震数据。@Transactional注解确保了在保存过程中如果出现异常可以进行回滚。
