hibernate - org.hibernate.MappingException : Repeated column in mapping for collection using @JoinTable

Question

我有以下(简化的)情况:

表 A 的字段:

• 身份证
• 通用

表 AB 的字段:

• 援助
• 出价通用
  

表 B 的字段:

• 身份证
• 通用

并且想要使用像这样的OneToMany将其与实体进行映射(在表A上映射的主类中):

@OneToMany(cascade = CascadeType.ALL, orphanRemoval = false, fetch = FetchType.LAZY)
@JoinTable(name = "AB", 
joinColumns= {
    @JoinColumn(name = "AID", referencedColumnName="ID"), 
    @JoinColumn(name = "COMMONID", referencedColumnName="COMMONID")},
inverseJoinColumns = {
    @JoinColumn(name = "BID", referencedColumnName="ID"), 
    @JoinColumn(name = "COMMONID", referencedColumnName="COMMONID")})
private Set<MyClassForB> list= new HashSet<MyClassForB>();

构建 session 时，出现以下错误:

org.hibernate.MappingException: Repeated column in mapping for collection using @JoinTable list column: COMMONID

我做错了什么？假设我是 Hibernate 新手。

Answer 1

尝试像这样添加可插入和可更新

@OneToMany(cascade = CascadeType.ALL, orphanRemoval = false, fetch = FetchType.LAZY)
@JoinTable(name = "AB", 
joinColumns= {
    @JoinColumn(name = "AID", referencedColumnName="ID", insertable = false, updatable = false), 
    @JoinColumn(name = "COMMONID", referencedColumnName="COMMONID", insertable = false, updatable = false)},
inverseJoinColumns = {
    @JoinColumn(name = "BID", referencedColumnName="ID", insertable = false, updatable = false), 
    @JoinColumn(name = "COMMONID", referencedColumnName="COMMONID", insertable = false, updatable = false)})
private Set<MyClassForB> list= new HashSet<MyClassForB>();

但我不确定您是否能够更新此集，我的用例是只读的。
