无法使用共享主键和复合主键

标签： java hibernate jpa

我正在使用Hibernate / JPA，并且在Hibernate类之间存在以下关系。

MediaRequestDetails＆lt; - ＆gt;披露（一对一共享主键） 披露＆lt; - ＆gt; DisclosureAuthor（一对多）

以下是课堂定义。

@Entity
@Table(name = "AW_REQUEST_DETAILS")
public class MediaRequestDetails implements WFPayload , Serializable{

        @Id
        @SequenceGenerator(name="REQUEST_ID_SEQ", sequenceName="REQUEST_ID_DBSEQ", allocationSize=1, initialValue = 1)
        @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "REQUEST_ID_SEQ")
        @Column(name = "ID", nullable = false)
        Long requestId;//id of the request

         @OneToOne(fetch=FetchType.LAZY,cascade = CascadeType.ALL,mappedBy = "mediaRequDetails")
    DisclosureDetails disclosureDetails;
}

披露明细课程定义

@Entity
@Table(name="AW_DISC_DETAILS")
public class DisclosureDetails implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;


    @Id 
    @Column(name = "REQUEST_ID")
    Long requestId;


    @Column(name="DISC_LANG")
    String discLanguage;

    @OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.ALL,orphanRemoval=true)
    @JoinColumn(name="REQUEST_ID", referencedColumnName="REQUEST_ID")
    Set<DisclosureAuthor> reqDiscAuthorsSet;

    @JoinColumn(name = "REQUEST_ID")
    @OneToOne(optional=false)
    @MapsId
    private MediaRequestDetails mediaRequDetails;

   //getter setter methods are here

   @PrePersist
public void prePersistCallBack(){
    if(reqDiscAuthorsSet!=null && reqDiscAuthorsSet.size() >0){
        for(DisclosureAuthor discAuthor:reqDiscAuthorsSet){

            DisclosureAuthorPK dpk=discAuthor.getPk();
            dpk.setRequestId(mediaRequDetails.requestId);
        }
    }
}

@PreUpdate
public void preUpdateCallBack(){
    if(reqDiscAuthorsSet!=null && reqDiscAuthorsSet.size() >0){
        for(DisclosureAuthor discAuthor:reqDiscAuthorsSet){

            DisclosureAuthorPK dpk=discAuthor.getPk();
            dpk.setRequestId(mediaRequDetails.requestId);
        }
    }
}

@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result
            + ((requestId == null) ? 0 : requestId.hashCode());
    return result;
}

/* (non-Javadoc)

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    DisclosureDetails other = (DisclosureDetails) obj;
    if (requestId == null) {
        if (other.requestId != null)
            return false;
    } else if (!requestId.equals(other.requestId))
        return false;
    return true;
}

}

披露作者类定义

@Entity
@Table(name="AW_DISC_AUTHOR")
public class DisclosureAuthor implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;


    @EmbeddedId
    private DisclosureAuthorPK pk;

  //getter and setter methods goes here

    /* (non-Javadoc)
 * @see java.lang.Object#hashCode()
 */
@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((pk == null) ? 0 : pk.hashCode());
    return result;
}


/* (non-Javadoc)
 * @see java.lang.Object#equals(java.lang.Object)
 */
@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    DisclosureAuthor other = (DisclosureAuthor) obj;
    if (pk == null) {
        if (other.pk != null)
            return false;
    } else if (!pk.equals(other.pk))
        return false;
    return true;
}

}

DisclosureAuthorPK 

@Embeddable
public class DisclosureAuthorPK implements Serializable {

    private static final long serialVersionUID = 1L;

    @Column(name = "REQUEST_ID", nullable = false)
    private Long requestId;
    @Column(name = "AUTHOR_ID", nullable = false)
    private Long authorsId

        @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result
                + ((authorsId == null) ? 0 : authorsId.hashCode());
        result = prime * result
                + ((requestId == null) ? 0 : requestId.hashCode());
        return result;
    }

    /* (non-Javadoc)
     * @see java.lang.Object#equals(java.lang.Object)
     */
    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        DisclosureAuthorPK other = (DisclosureAuthorPK) obj;
        if (authorsId == null) {
            if (other.authorsId != null)
                return false;
        } else if (!authorsId.equals(other.authorsId))
            return false;
        if (requestId == null) {
            if (other.requestId != null)
                return false;
        } else if (!requestId.equals(other.requestId))
            return false;
        return true;
    }

}

我正在尝试使用以下程序更新mediarequestDetails。 requestId 187已经有三个与数据库相关联的作者。 但是在下面的程序中，我只是在集合中添加了一个作者，其余的两个作者必须从数据库中删除，这是我的期望。

public class TestDisclosureSample {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        EntityManager entityManager = Persistence.createEntityManagerFactory("rawsjpa").createEntityManager();
       //prepare mediarequest object
       MediaRequestDetails obj=new MediaRequestDetails();
       obj.setRequestId(187L);
        obj.setRequestType("MDA");

       //prepare disclosure details
       DisclosureDetails discDetails=new DisclosureDetails();
        discDetails.setRequestId(187L);
        discDetails.setDiscLanguage("English");
        discDetails.setMediaRequDetails(obj);
        obj.setDisclosureDetails(discDetails);       

      DisclosureAuthor dscauthor1=new DisclosureAuthor();
        DisclosureAuthorPK pk1 = new DisclosureAuthorPK();
        pk1.setAuthorsId(1237L);
        pk1.setRequestId(187L);
        dscauthor1.setPk(pk1);
        //dscauthor1.setMediaRequDetails(obj);
        discAuthorSet.add(dscauthor1);

     Session session =(Session)entityManager.getDelegate();
        if(entityManager!=null){
            System.out.println("************* EntityManager is obtained for Updation*****************");
            Transaction tx=session.beginTransaction();

            session.saveOrUpdate(obj);
            tx.commit();
        }   

        session.close();

  }
}

当我执行上述程序时，我得到以下输出，但有异常。
