mappedBy 引用了一个未知的目标实体属性：dataObject.PayTransactionStatement.payMaster 中的 ataObject.PayMaster.PayTransactionStatement

Question

我遇到错误

org.hibernate.AnnotationException: mappedBy 引用了一个未知的目标实体属性：my.backend.dataObject.PayTransactionStatement.payMaster 中的 my.backend.dataObject.PayMaster.PayTransactionStatement。

我检查了所有实体，但仍然无法解决问题

@Data
@Entity
@Table(name = "pay_master")
@DynamicUpdate //Dynamic update - you need to set the update time field of the database to be automatically updated. In this way, query the time, save the other fields and save the update time.
public class PayMaster {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="paymaster_id")
    private Long paymasterid;


    @ManyToOne(fetch= FetchType.LAZY)
    @JoinColumn(name="statement_id")
    private PayTransactionStatement payTransactionStatement;

}



@Data
@Entity
@Table(name = "pay_transaction_statement")
@DynamicUpdate
public class PayTransactionStatement {


     @Id
     @GeneratedValue(strategy = GenerationType.AUTO)
     @Column(name="statement_id")
     private Long statementId;

     @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy ="PayTransactionStatement") 
     private List<PayMaster> payMaster;

}

Answer 1

您在PayTransactionStatement 中的映射应该是

 @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy ="payTransactionStatement") 
 private List<PayMaster> payMaster;
