Question

例如，我有两个实体：

minikube v1.6.2 on Ubuntu 19.10
  Selecting 'none' driver from user configuration (alternates: [])
  Tip: Use 'minikube start -p <name>' to create a new cluster, or 'minikube delete' to delete this one.
  Using the running none "minikube" VM ...
  Waiting for the host to be provisioned ...
  Preparing Kubernetes v1.17.0 on Docker '19.03.2' ...
     kubelet.resolv-conf=/run/systemd/resolve/resolv.conf
  Launching Kubernetes ...

Error starting cluster: running cmd: /bin/bash -c "sudo env PATH=/var/lib/minikube/binaries/v1.17.0:$PATH kubeadm init phase certs all --config /var/tmp/minikube/kubeadm.yaml": /bin/bash -c "sudo env PATH=/var/lib/minikube/binaries/v1.17.0:$PATH kubeadm init phase certs all --config /var/tmp/minikube/kubeadm.yaml": exit status 1

?  minikube is exiting due to an error. If the above message is not useful, open an issue:

是存储位置的实体，并且

@Builder
@Entity(name = "orders")
public class Order {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "user_id", referencedColumnName = "id")
    private User user;

    private Date orderDate;

    @Column(name = "status", length = 60)
    private String status;

    @OneToMany(mappedBy = "order")
    private Collection<OrderPosition> orderPositions;

    @OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "address_id", referencedColumnName = "id")
    private OrderAddress orderAddress;
}

按顺序存储单个职位，问题是：我可以通过这种方式将行保存在数据库中吗（示例）：

@Builder
@Entity(name = "order_position")
public class OrderPosition {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "order_id", referencedColumnName = "id", nullable = false)
    private Order order;

    @ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "product_id", referencedColumnName = "id", nullable = false)
    private Product product;

    private Integer count;
    private BigDecimal unitPrice;
}

如果没有，我应该怎么做？

在Spring中插入数据-CrudRepository
