第二次编辑：将PrimaryAccount类中的“Primary Transaction”更正为“PrimaryTransaction”，即类名。
@Entity
public class PrimaryAccount {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private int accountNumber;
private BigDecimal accountBalance;
@OneToMany(mappedBy ="PrimaryAccount", cascade=CascadeType.ALL, fetch = FetchType.LAZY)
@JsonIgnore
private List<PrimaryTransaction> PrimaryTransaction;
得到低于错误
