JPAでテーブルにインデックスを貼る
JPA(Java Persistence API) は仕様の定義で, 実装が Hibernate
@Entity
@Table(indexes = @Index(columnList = "message1,message2"))
public class NewEntity implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String message1;
