我有一个名为Author的实体,如下所示.我想在字段"name"上添加一个唯一约束.

@Entity
@Table(name = "author")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
@Document(indexName = "author")
public class Author implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @NotNull
    @Column( name = "name")
    private String name;


    @Column(name = "birth_date")
    private LocalDate birthDate;
