使用spring boot JPA在数据库中插入多行

@Entity
@Table(name = "your_table_name")
public class YourEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "column_name")
    private String columnName;

    // 其他属性和对应的getter/setter方法
}

public interface YourRepository extends JpaRepository<YourEntity, Long> {
}

@Service
public class YourService {
    private final YourRepository yourRepository;

    public YourService(YourRepository yourRepository) {
        this.yourRepository = yourRepository;
    }

    public void insertMultipleRows(List<YourEntity> entities) {
        yourRepository.saveAll(entities);
    }
}

@RestController
public class YourController {
    private final YourService yourService;

    public YourController(YourService yourService) {
        this.yourService = yourService;
    }

    @PostMapping("/insert")
    public void insertMultipleRows() {
        List<YourEntity> entities = new ArrayList<>();
        // 创建多个实体对象并添加到列表中

        yourService.insertMultipleRows(entities);
    }
}
