java JPA HIbernate在生成的类中缺少列

Question

我有一个具有2个外键的实体。 这个类是生成的

@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(DcDataDomaninDs.class)
public abstract class DcDataDomaninDs_ {
    public static volatile SingularAttribute<DcDataDomaninDs, Integer> id;
    public static volatile SingularAttribute<DcDataDomaninDs, DatasetType> datasetType;

}

从中生成的实体类如下所示。我看不出datasetype和dataDomain之间有什么不同之处。我省略了其他简单的专栏，因为它们工作得很好

@Entity
@Table(name = "DC_DATA_DMN_DS")
public class DcDataDomaninDs implements Serializable {

    private static final long serialVersionUID = 1L;

    public DcDataDomaninDs() {
    }

    @Id
    @Column(name="DMN_DS_ID")
    private int id;


    private DataDomain dataDomain;


    private DatasetType datasetType;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    @ManyToOne
    @JoinColumn(name="DATA_DMN_CD")
    public DataDomain getDataDomain() {
        return dataDomain;
    }

    public void setDataDomain(DataDomain dataDomain) {
        this.dataDomain = dataDomain;
    }

    @ManyToOne
    @JoinColumn(name="DS_TYP_CD")
    public DatasetType getDatasetType() {
        return datasetType;
    }

    public void setDatasetType(DatasetType datasetType) {
        this.datasetType = datasetType;
    }

}

生成的类DataDomain_uuu和DatasetType_uuuuuuu中都包含该连接类的集合

public static volatile SetAttribute<DataDomain, DcDataDomaninDs> dataDomainDs;
public static volatile SetAttribute<DatasetType, DcDataDomaninDs> dataDomainDs;

根据要求，这里是缺失实体的映射

@Entity
@Table(name = "DC_DATA_DMN")
public class DataDomain {

    @Id
    @Column(name = "DATA_DMN_CD",updatable = false,insertable = false, nullable = false, length = 30)
    private String code;

    @Column(name = "DATA_DMN_NM", nullable = false, length = 100)
    private String name;

    private Set<DcDataDomaninDs> dataDomainDs;

    @OneToMany( mappedBy = "dataDomain")
    public Set<DcDataDomaninDs> getDataDomainDs() {
        return dataDomainDs;
    }

我试着运行我的测试，它不需要缺少的值，得到了这个响应

Answer 1

DataDomain类不可序列化，就是这样
