JPA @OneToMany dernek kullanırken @JoinColumn ve mappedBy arasındaki fark nedir
Arasındaki fark nedir: @Entity public class Company { @OneToMany(cascade = CascadeType.ALL , fetch = FetchType.LAZY) @JoinColumn(name = "companyIdRef", referencedColumnName = "companyId") private List<Branch> branches; ... } ve @Entity public class Company { @OneToMany(cascade = CascadeType.ALL , fetch = FetchType.LAZY, mappedBy = "companyIdRef") private List<Branch> branches; ... }
