Upaya ilegal untuk memetakan bukan koleksi sebagai @OneToMany, @ManyToMany atau @CollectionOfElements

Kesalahan menunjukkan bahwa private Lawyer lawyer perlu koleksi karena merupakan @OneToMany hubungan. Di Country kelas, hubungan terakhir harus

@OneToMany(targetEntity = Lawyer.class, cascade = { CascadeType.ALL }, orphanRemoval = true)
@JoinTable(name = "lawyer_cscd", joinColumns = {
    @JoinColumn(name = "country_code", referencedColumnName = "country_code") }, inverseJoinColumns = {
    @JoinColumn(name = "lawyer_batch_no", referencedColumnName = "lawyer_batch_no") })
private Set<Lawyer> lawyer;
// or a Collection/List/etc.
