映射实体：

@Data
@Entity
public class FundDrFmpfmance {
   
    @Column(name="PERSONCODE")
    private String personCode;

    @Column(name="NATUREPOSTYEAR")
    private BigDecimal naturepostYear;

}

 解决方案：

修改实体， 添加 @Id 注解

@Data
@Entity
public class FundDrFmpfmance {
    @Id
    @Column(name="PERSONCODE")
    private String personCode;

    @Column(name="NATUREPOSTYEAR")
    private BigDecimal naturepostYear;

}
