Java Hibernate@ManyToMany映射与复合键

我试图映射两个表之间的许多关系，这两个表都有复合主键

LSFOCTB which primary key is composed of : LSFOC_CODSOC,LSFOC_CODLSC,LSFOC_CODFOC

LSFORTB which primary key is composed of : LSFOR_CODSOC,LSFOR_CODLSC,LSFOC_CODFOR

The table in charge of the ManyToMany relationship is :

LSFCFTB, with : LSFCF_CODSOC,LSFCF_CODLSC,LSFCF_CODFOC,LSFCF_CODFOR

因此，在hibernate模型映射LSFOCTB中，我尝试了：

@ManyToMany(targetEntity = package.LSFOCTB.class, cascade = { CascadeType.PERSIST,
            CascadeType.MERGE })
    @JoinTable(name = "LSFCFTB", joinColumns = {
            @JoinColumn(name = "LSFCF_CODLSC", referencedColumnName = "LSFOC_CODLSC"),
            @JoinColumn(name = "LSFCF_CODFOC", referencedColumnName = "LSFOC_CODFOC"),
            @JoinColumn(name = "LSFCF_CODSOC", referencedColumnName = "LSFOC_CODSOC") }, 
    inverseJoinColumns = { @JoinColumn(name = "LSFCF_CODLSC", referencedColumnName = "LSFOR_CODLSC"),
            @JoinColumn(name = "LSFCF_CODFOR", referencedColumnName = "LSFOR_CODFOR"),
            @JoinColumn(name = "LSFCF_CODSOC", referencedColumnName = "LSFOR_CODSOC") })

在getter之前。 但它不会起作用。。。 尝试访问远程集合时出现的错误是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [beans-dao.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: Repeated column in mapping for collection: package.LSFOCTB.distantCollection column: LSFCF_CODLSC

您是否已经设法使hibernate映射适用于多个关系？ 如果是，我的映射有什么问题？

谢谢你的帮助

问题似乎在于，您正在创建一个包含6列的联接表，并且列的名称重复。实际上，您正在创建两个名为LSFCF\u CODLSC的列，以及两个名为LSFCF\u CODFOR的列和两个名为LSFCF\u CODSOC的列

我建议你试试这个：

@JoinTable(name = "LSFCFTB", joinColumns = {
                    @JoinColumn(name = "LSFOC_LSFCF_CODLSC", referencedColumnName = "LSFOC_CODLSC"),
                    @JoinColumn(name = "LSFOC_LSFCF_CODFOC", referencedColumnName = "LSFOC_CODFOC"),
                    @JoinColumn(name = "LSFOC_LSFCF_CODSOC", referencedColumnName = "LSFOC_CODSOC") }, 
        inverseJoinColumns = { @JoinColumn(name = "LSFOR_LSFCF_CODLSC", referencedColumnName = "LSFOR_CODLSC"),
                    @JoinColumn(name = "LSFOR_LSFCF_CODFOR", referencedColumnName = "LSFOR_CODFOR"),
                    @JoinColumn(name = "LSFOR_LSFCF_CODSOC", referencedColumnName = "LSFOR_CODSOC") })

或者类似的（根据您的命名约定）为每一列指定一个唯一的名称。

或者类似的东西（根据您的命名约定），为每列指定一个唯一的名称。

我一直在寻找以下页面的信息：第2.2.5.3.3章。多对多，还有：我一直在寻找以下页面上的信息：章节：2.2.5.3.3。多对多以及：数据库中名为LSFCFTB的表中的列的名称是什么？name=“existing column name”和referencedColumnName=“正在引用的列的名称”数据库中名为LSFCFTB的表中的列的名称是什么？name=“现有列名”和referencedColumnName=“被引用列的名称”
