我的实体

public class CarModelEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "model_id")
    private Integer modelId;
    @Column(name = "model_name")
    private String modelName;
    @Column(name = "is_parent")
    private Integer isParent;
    @Column(name = "parent_id")
    private Integer parentId;
    @Column(name = "created_by")
    private Integer createdBy;
    @Column(name = "created_at")
    private Timestamp createdAt;
    @Column(name = "updated_at")
    private Timestamp updatedAt;

}

我的代码：

CarModelEntity data = carModelRepo
                        .saveAllAndFlush(CarModelEntity.builder()
                                .isParent(1)
                                .modelName(value)
                                .build());

语法错误：

Error:(49, 25) java: method saveAllAndFlush in interface org.springframework.data.jpa.repository.JpaRepository<T,ID> cannot be applied to given types;
  required: java.lang.Iterable<S>

  reason: cannot infer type-variable(s) S

我的存储库：

public interface CarModelRepo extends JpaRepository<CarModelEntity, Integer> {
}
