public interface OrderRepository extends CrudRepository<Orders, Integer> {
// Spring Data - use JPQL -> generate SQL query on runtime
public List<Orders> findByName(String name);

Модели:
@Entity
public class Orders {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
@NotNull
private String name;
private String description;
@NotNull
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date created;
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date updated;
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "category_id")
private Category category;
@Entity
public class Category {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
@NotNull
private String name;

@NotNull
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date created;
@DateTimeFormat(pattern = "dd.MM.yyyy HH:mm:ss")
private Date updated;
@OneToOne(fetch = FetchType.LAZY,
cascade = CascadeType.ALL,
mappedBy = "category")
private Orders orders;
И вот результат:
