Question

当我尝试级联保存内部集合为“ OneToMany”的所有实体时，它将返回错误。

错误：

o.h.engine.jdbc.spi.SqlExceptionHelper：SQL错误：2291，SQLState：23000 o.h.engine.jdbc.spi.SqlExceptionHelper：ORA-02291：违反完整性约束（MACHINE.OFFICER_FK）-找不到父键

@Entity(name = "GenInfo")
@Table(name = "GEN_INFO")
public class GenInfo {

    @Id
    @GeneratedValue(generator = "GEN_INFO_SEQ")
    @Column(name = "ID_GEN_INFO")
    Long id;

    @Column(name = "STREET_ADDRESSS")
    String streetAddress;

    @Column(name = "CITY")
    String city;

    @Column(name = "STATE_REGION")
    String stateOrRegion;

    @Column(name = "POSTAL_CODE")
    String PostalCode;

    @Column(name = "COUNTRY")
    String Country;

    @Column(name = "CONTACT_NAME")
    String ContactName;

    @Column(name = "CONTACT_TITLE")
    String ContactTitle;

    @OneToMany(mappedBy = "genInfo", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.LAZY)
    List<Officer> officerCollection;

}

@Entity(name = "Officer")
@Table(name = "OFFICER")
public class Officer {

    @Id
    @GeneratedValue(generator = "OFFICER_SEQ")
    @Column(name = "ID_OFFICER")
    Long id;

    @Column(name = "OFFICER_NUM")
    String officerID;

    @Column(name = "PERSON_ID")
    String personID;

    @Column(name = "OF_RANK")
    String rank;

    @Column(name = "STATUS")
    String status;

    @Column(name = "TITLE")
    String LongTitle;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "ID_GEN_INFO")
    private GenInfo genInfo;
}

这是带有一些休眠信息的日志

Answer 1

似乎您持有的父键信息 contact_name表中gen_info列中的officer列和officer_id列中（假定），并试图将一个不匹配的值插入gen_info中officer.officer_id

的值

违反完整性约束-在级联上找不到父键
