org.hibernate.PersistentObjectException：分离的实体被传递以持久保存在新对象上

Question

I know there are many of these threads, but nothing of their solutions would work for me.

public void process(EreignisTexteSpezifikationEingang spezifikationEingang) throws BusinessException {

        String eingangBaureiheBauart = spezifikationEingang.getBaureiheBauart();
        String eingangSoftwareVersion = spezifikationEingang.getSoftwareVersion();
        boolean eingangIsDeault = spezifikationEingang.getIsDefault();
        AnlageStatus anlageStatus = spezifikationEingang.getAnlageStatus();

        Assert.argNotNull(spezifikationEingang, "EreignisTexteSpezifikationEingang");
        Assert.argNotNull(eingangBaureiheBauart, "BaureiheBauart");
        Assert.argNotNull(eingangSoftwareVersion, "Software Version");
        Assert.argNotNull(spezifikationEingang.getInputStream(), "texteInputStream");

        checkExistDefaultVersionForBR(eingangBaureiheBauart, eingangIsDeault);

        EreignisSpezifikation newSpez = new EreignisSpezifikation();
        newSpez.setAnlageDatum(new Date());
    newSpez.setSoftwareVersion(eingangSoftwareVersion);
    newSpez.setIsDefault(eingangIsDeault);
    newSpez.setBemerkung(spezifikationEingang.getBemerkung());

    if (AnlageStatus.UNDEFINED.equals(anlageStatus) || null == anlageStatus) {
        newSpez.setStatus(AnlageStatus.VERFUEGBAR);
    } else {
        newSpez.setStatus(anlageStatus);
    }

    BaureiheBauart baureiheBauart = bauartDao.findByName(eingangBaureiheBauart);
    newSpez.setBaureiheBauart(baureiheBauart);
    if (baureiheBauart == null) {
        throw InvalidEreignisSpezifikationException.invalidBaureihe(eingangBaureiheBauart, spezifikationEingang
                .getFilename());
    }

    EreignisTexteParser parser = parserFactory.getEreignistexteParser();

    List<Ereignistext> texte = parser.parse(spezifikationEingang.getInputStream());

    newSpez.setEreignistexte(texte);

        ereignisSpezifikationDao.makePersistent(newSpez);

EreignisSpezifikation:

    ...
    @Id
    @Column(name = "PK_EREIGNIS_SPEZ")
    @SequenceGenerator(name = "EreignisSpezSequence", sequenceName = "SEQ_EREIGNIS_SPEZIFIKATION", allocationSize=1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "EreignisSpezSequence")
    private Long id;

    ...
    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "FK_EREIGNIS_SPEZ", nullable = false)
    List<Ereignistext> ereignistexte;

The Last index of the sequence is 189 which is NOT set.

I've already tried to change the CascadeType to Merge but changes nothing.

This Object is definitely not in the database still it fails. Any ideas?

Answer 1

The exception clearly says:

detached entity passed to persist on new Object

Your problem is that you are setting some properties that you take from spezifikationEingang object to your newSpez object, For hibernate these objects are not persisted because they haven't been loaded in the current session context.

For example in the following lines:

List<Ereignistext> texte = parser.parse(spezifikationEingang.getInputStream());

newSpez.setEreignistexte(texte);

You are trying to set texte to your newSpez object, while it is a non persisted List , because you have just created it from parser.parse() call.
