JPA: @JoinTable - Both columns are Primary Keys.. How do I stop that?

Question

This is my annotation I use to generate my Join Table.

@OneToMany(cascade = CascadeType.ALL)
@JoinTable(name = \"service_operations\", 
        joinColumns         


        

Answer 1

I fixed my problem by adding the following changes:

I changed my @OneToMany to a @ManyToMany annotation

@ManyToMany(cascade = CascadeType.ALL)
@JoinTable(name = "workflow_services", 
        joinColumns = @JoinColumn(name = "workflow_id"), 
        inverseJoinColumns = @JoinColumn(name = "service_id"))
public Set getServices() {
    return services;
}

I added a Set workflows; association in my Service object

@ManyToMany(mappedBy="services")  // map info is in person class
public Set getWorkflows() {
    return workflows;
}
