Should Hibernate be able to handle overlapping foreign keys?

Question

I have a table that has two foreign keys to two different tables with both foreign keys sharing one column:

CREATE TABLE ZipAreas
(
  countr         


        

Answer 1

This is still not solved in Hibernate 5. However, if I use @JoinColumnsOrFormulas I get ClassCastException. Appending insertable = false, updatable = false on all join columns solved my problem:

Example:

@ManyToOne
@JoinColumns(value = {
    @JoinColumn(name = "country_code", referencedColumnName = "country_code", insertable = false, updatable = false),
    @JoinColumn(name = "state_code", referencedColumnName = "state_code", insertable = false, updatable = false), 
    @JoinColumn(name = "city_name", referencedColumnName = "name", insertable = false, updatable = false)})
private City city = null;
