java - Hibernate 不考虑要插入的字段

问题描述

好的，

我是 HIbernate 的新手，我遇到了一个问题，我需要支持来尝试解决它。

我有一个客户端类，这个类包含复合键。

@Entity
@Table(name = "Clientes")
@IdClass(ClientePK.class)
public class Cliente implements Serializable {

    //@EmbeddedId
    //private ClientePK clientePK;
    @Id
    @Column(name = "Id_Cliente", nullable = false, length = 15)
    private long idCliente;

    @Id
    @Fetch(FetchMode.SELECT)
    @ManyToOne
    @JoinColumn(name = "Loja", nullable = false)
    private Loja loja;

}

public class ClientePK implements Serializable {

    private long idCliente;
    private Loja loja;
}

然后我有一个 ClientClass 类也包含复合键

@Entity
@Table(name = “Clientes_Historicos”)
@IdClass(ClienteHistoricoPK.class)
public class ClienteHistorico implements Serializable {

    @Id
    @Resolvable(colName = "Id. Cliente Histórico")
    @Column(name = "Id_Cliente_Historico", nullable = false)
    private Long idClienteHistorico;

    @Id
    @Fetch(FetchMode.SELECT)
    @ManyToOne
    @JoinColumn(name = "Loja", nullable = false)
    private Loja loja;

    @Resolvable(colName = "Cliente")
    @Fetch(FetchMode.SELECT)
    @JoinColumns({
        @JoinColumn(name = "id_cliente", referencedColumnName = "Id_Cliente", nullable = false, insertable = true)
        ,
        @JoinColumn(name = "loja", referencedColumnName = "loja", nullable = false, insertable = false, updatable = false)
    })
    @MapsId("loja")
    @ManyToOne(optional = false)
    private Cliente cliente;

}

我使用了@MapsId 注解（“store”）来指示主键的 store 字段应该与客户端连接本身的 FK 字段一起使用。

发生在 ClientHistorico 中执行插入时，未考虑插入客户端字段。

谢谢你。
