| I am using hibernate-JPA version 2.1 and I can reproduce this issue. Test case : Logically there are two columns matching within two classes A1, A2, A3 but I need to create relation based on Just A1. It is one to Many relation between Class A and Class B.
My relations looks like below:
Class A { String varA1; String varA2; String varA3; String varA4; @OneToMany(mappedBy=aObj") List<B> bList = new ArrayList<B>(); } Class B { String varA1; String varA2; String varA3; String varB4; @ManyToOne(targetEntity = A.class) @JoinColumn(name ="A1", referencedColumnName = "A1" , insertable = false, updatable = false) A aObj; } Error:
Caused by: org.hibernate.AnnotationException: referencedColumnNames(A1) of B.aObj referencing A not mapped to a single property
