org.hibernate.MappingException:使用@JoinTable进行收集的映射中的重复列 [英] org.hibernate.MappingException: Repeated column in mapping for collection using @JoinTable

问题描述

我有以下(简化)情况:

I have the following (simplified) situation:

表A的字段:

• ID
• COMMONID

表AB的字段:

• AID
• 出价 COMMONID
  

• AID
• BID COMMONID
  

表B的字段:

• ID
• COMMONID

，并希望使用这样的OneToMany将其与实体映射(在映射到表A的主类中):

and want to map it with entities using a OneToMany like this (in the master class mapped on table A):

@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>();

建立会话时，出现以下错误:

Building the session, I obtain the following error:

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

我做错了什么?认为我是Hibernate的新手.

What am I doing wrong? Consider that I'm new to Hibernate.

推荐答案

尝试添加可插入且可更新的内容

Try to add insertable, and updateable like this

@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>();

但是我不确定您是否能够更新此设置，我的用例是只读的.

But I'm not sure whether you will able to update this set, my use case was read only.
