我有一個實體 Job 如下。@Entity@Getter@Setter@NoArgsConstructor@Immutable@ToString@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})@Table(name = "JOB")public class Job extends BaseEntity implements IEntity, IDto {  @Id  @Column(name = "JOB_ID", unique = true, nullable = false)  private Long id;  @Column(name = "PRINT_JOB_ID", length = 30)  private String printJobId;  @OneToMany(fetch = FetchType.LAZY)  @JoinColumn(name = "PRINT_JOB_ID", nullable = false, insertable = false, updatable = false)  private Set<PrintFile> printFileInfos = new HashSet<PrintFile>();}我還有另一個實體 PrintFile。@Entity@Getter@Setter@NoArgsConstructor@Immutable@Table(name = "PRINT_FILE")public class PrintFile implements Serializable {  @Id  @Column(name = "FILE_ID", unique = true, nullable = false, length = 50)  private String fileId;  @Column(name = "PRINT_JOB_ID", nullable = false, length = 30)  private String printJobId;}這是我的桌子。JobJOB_ID                     NOT NULL NUMBER PRINT_JOB_ID                        VARCHAR2(30)  Print_FilePRINT_JOB_ID               NOT NULL VARCHAR2(30)  FILE_ID                    NOT NULL VARCHAR2(50) 嘗試使用 Sprint 引導休息 API 獲取作業數據時，java.sql.SQLSyntaxErrorException: ORA-01722: invalid number出現錯誤。所有的數據類型映射似乎都是正確的，還有什么可能出錯的？編輯：當我擺脫聯接時，作業實體可以毫無問題地獲取。即 Job 實體中 printFileInfos 的整個聲明。這讓我認為問題出在 join 或 PrintFile 實體中。
