I'm a bit of a newb myself, but I think you need to change your
UserProperties like below -



@Entity
@Table(name="userproperties")
public class UserProperties implements Serializable {

        @Id
        @Column(name="id", nullable=false)
        @GeneratedValue(strategy=GenerationType.IDENTITY)
        private Integer id;
        
        @ManyToOne(mappedBy="UserInfo", fetch=FetchType.LAZY)
        @JoinColumn(name="user_id", referencedColumnName="id")
        private UserInfo userInfo;
