Question

我正在使用spring数据jpa，并希望更改实体之间发生的默认连接列。例如，在以下映射中，

在Account.java中，

   @OneToMany(mappedBy = "account")
   @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
   private Set<Invoice> invoices = new HashSet<>();

在Invoice.java

中

@ManyToOne
private Account account;

默认情况下，id的{{1}}列与Account account_id的{{1}}按照给定的一对多和多对一的映射加入，这也是有效的对于我来说足够了。但现在我的要求是Invoice account_id加入Invoice的{{1}}而不是id，我希望Account的另一个字段account_number成为Invoice加入id的{{1}}，在我的一对多和多对一的映射中。可能吗？作为一条线索，我对Account

进行了以下更改

Invoice

但是我收到以下错误：

 @ManyToOne
 @JoinColumn(name="account_number", nullable=false)
 private Account account;

Account.java

Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.trace.domain.Invoice column: account_number (should be mapped with insert="false" update="false")

Answer 1

正如错误消息所示，同一列有两种不同的映射：account_number。事实上，你有

@Column(name = "account_number")
private String accountNumber;

在您的实体中，该帐户字段是多余的。

您只需删除该字段。

需要在弹簧数据jpa中更改一对多和多对一映射中的默认连接列
