Hibernate 插入具有联接列的实体

我想在数据库中插入具有两个联接列的实体“CategorieTresorerie”。问题是，其中一个（RegroupmentCategorieTreeSorrie）正在尝试自动插入。。。但这个已经在数据库中，所以我有一个重复的键值冲突异常

错误代码：

Hibernate: insert into "RegroupementCategorieTresorerie" ("RegroupementCategorieTresorerieCode") values (?)
2015-12-29 15:32:05.207  WARN 6960 --- [tomcat-http--26] o.h.engine.jdbc.spi.SqlExceptionHelper   : SQL Error: 0, SQLState: 23505

  Détail : Key ("RegroupementCategorieTresorerieCode")=(MARGE_BRUT) already exists.

org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [RegroupementCategorieTresorerie_PK]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

我要插入的类：

@Entity
public class CategorieTresorerie
    {
    @Id
    @Column(name="CategorieTresorerieID")
    @SequenceGenerator(name = "CategorieTresorerie_CategorieTresorerieID_seq", sequenceName = "\"CategorieTresorerie_CategorieTresorerieID_seq\"", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "CategorieTresorerie_CategorieTresorerieID_seq")
    private Integer categorieTresorerieId;

    @MapsId
    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "regroupementCategorieTresorerieCode", insertable = false, updatable = false)
    @Fetch(FetchMode.JOIN)
    private RegroupementCategorieTresorerie regroupement;

    @MapsId
    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "typeCategorieTresorerieId", insertable = false, updatable = false)
    @Fetch(FetchMode.JOIN)
    private TypeCategorieTresorerie typeCategorieTresorerie;

    private Boolean estActif = true;

Join类RegroupmentCategorieTreesOrrie是hibernate尝试自动插入的一个：

@Entity
public class RegroupementCategorieTresorerie implements EstTraductible
{
    @Id
    private String regroupementCategorieTresorerieCode;

    @Transient
    private String libelle;

联接列类型分类目录：

@Entity
public class TypeCategorieTresorerie
    {
    @Id
    @Column(name = "TypeCategorieTresorerieID")
    private Integer typeCategorieTresorerieId;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "CategorieTresorerieFamilleID", insertable = false, updatable = false)
    @Fetch(FetchMode.JOIN)
    private CategorieTresorerieFamille famille;

在不自动插入联接列的情况下，如何插入CategorieTresorerie

谢谢您的帮助。

在没有看到插入代码的情况下，不确定您到底想做什么，但是如果您试图加入一个已经存在的实体，请尝试获取它并指向获取的实体（带有id）因此hibernate不会尝试创建新记录。

您应该添加显示如何持久化CategorieTresorerie的代码。您好，感谢您的帮助，我删除了“insertable=false，Updateable=false”，现在它工作得很好！
