在Spring Boot中,可以使用JPA和Hibernate來批量新增數(shù)據(jù)。
首先,確保已經(jīng)配置了JPA和Hibernate依賴項(xiàng)。然后,創(chuàng)建一個(gè)實(shí)體類,表示待新增的數(shù)據(jù):
@Entity
@Table(name = "your_table")
public class YourEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
// getters and setters
}
接下來,創(chuàng)建一個(gè)Repository接口,用于操作數(shù)據(jù)庫:
@Repository
public interface YourRepository extends JpaRepository<YourEntity, Long> {
}
然后,在你的Service類中,注入YourRepository,并編寫批量新增的方法:
@Service
public class YourService {
@Autowired
private YourRepository yourRepository;
public void batchSave(List<YourEntity> entities) {
yourRepository.saveAll(entities);
}
}
最后,在你的Controller中,調(diào)用批量新增的方法:
@RestController
public class YourController {
@Autowired
private YourService yourService;
@PostMapping("/batch")
public void batchSave(@RequestBody List<YourEntity> entities) {
yourService.batchSave(entities);
}
}
現(xiàn)在,當(dāng)發(fā)送POST請求到/batch
接口時(shí),傳遞一個(gè)包含待新增數(shù)據(jù)的JSON數(shù)組,Spring Boot將會自動將數(shù)據(jù)保存到數(shù)據(jù)庫中。
