我有两个对象Antrag(应用程序)和Anlage(设施)。可以为多个设施申请。该应用程序直接保存在DAO中。设施通过级联保持。
@Entity
@Table(name = "EEG_ANTRAG")
public class Antrag implements Serializable {
private static final long serialVersionUID = -2440344011443487714L;
@Id
@Column(name = "ANT_ID", nullable = false)
@SequenceGenerator(name = "sequenceGeneratorAntrag", sequenceName = "EEG_ANTRAG_SEQ", allocationSize = 1)
@GeneratedValue(generator = "sequenceGeneratorAntrag")
@Getter @Setter private Long id;
@OneToMany(mappedBy = "antrag", cascade = { CascadeType.ALL }, orphanRemoval = true)
@OrderBy("id ASC")
@Getter private List<Anlage> anlageList = new ArrayList<Anlage>();
public Anlage addAnlage(Anlage anlage)
anlageList.add(anlage);
anlage.setApplication(this);
return anlage;
}
/* some more simple attributes; just Strings, boolean, .. */
}
@Entity
@Table(name = "EEG_ANLAGE")
public class Anlage implements Serializable {
private static final long serialVersionUID = -3940344011443487741L;
@Id
@Column(name = "ANL_ID")
@SequenceGenerator(name = "sequenceGeneratorAnlage", sequenceName = "EEG_ANLAGE_SEQ", allocationSize = 1)
@GeneratedValue(generator = "sequenceGeneratorAnlage")
@Getter @Setter private Long id;
@ManyToOne
@JoinColumn(name = "ANL_ANT_ID")
@Getter @Setter private Antrag antrag;
/* some more simple attributes; just Strings, boolean, .. */
}
@Stateless
public class AntragDaoBean implements AntragDaoLocal {
@PersistenceContext(unitName = "ejb-model")
private EntityManager em;
@Override
public void persistAntrag(Antrag antrag) {
em.persist(antrag);
}
}
插入设施时发生错误,例如某些列名在实体中拼写错误,抛出异常。 stacktrace表示已执行回滚。问题是,应用程序仍然存在。是否应该回滚应用程序的插入? 我们正在使用EclipseLink 2.4.1。 EclipseLink调试输出指出,所有插入都在一个事务中执行。该数据库是Oracle 11g。 我对交易行为的怀疑是错误的吗?我如何得到我想要的行为?

答案 0 :(得分:8)
您的期望是正确的:所有内容都应该在一个事务中完成,Antrag
的插入也应该回滚。
我认为你的持久性单元根本不是JTA:在persistence.xml
文件中测试你有类似的东西:
<persistence-unit name="ejb-model" transaction-type="JTA">
<jta-data-source>java:/someNameDB</jta-data-source>
