如何使用Spring Boot将JSON数据文件导入mongodb？

// 实体类
@Document(collection = "data")
public class DataEntity {
    @Id
    private String id;
    private String name;
    // 其他字段及对应的getter和setter方法
}

// 数据访问层
@Repository
public interface DataRepository extends MongoRepository<DataEntity, String> {
}

// 服务层
@Service
public class DataService {
    @Autowired
    private DataRepository dataRepository;

    public void importDataFromJsonFile(String filePath) throws IOException {
        ObjectMapper objectMapper = new ObjectMapper();
        List<DataEntity> dataList = objectMapper.readValue(new File(filePath), new TypeReference<List<DataEntity>>() {});
        dataRepository.saveAll(dataList);
    }
}

// 控制器层
@RestController
public class DataController {
    @Autowired
    private DataService dataService;

    @PostMapping("/import")
    public void importData(@RequestParam("file") MultipartFile file) throws IOException {
        dataService.importDataFromJsonFile(file.getOriginalFilename());
    }
}
