JEE，eclipselink，glassfish4.0无法持久化实体

Question

我正在开发的其余应用程序存在一个奇怪的问题。

我创建了实体类以及dao类来管理它们。 现在，当我将应用程序部署到服务器上时，可以看到我的数据库架构正在更新。 现在我有这个：

@Stateless
    @Produces("text/plain")
    @Path("cc")
    public class HelloService {

        @EJB
        private DomainDao dao;

        @GET
        @Path("/put")
        public String put() {

            Domain d = new Domain();
            d.setName("name");
            d.setActive(true);
            d.setCreationDate(new Date());
            d.setLastModificationDate(new Date());

            dao.create(d);

            return "completed";
        }

        @GET
        @Path("/get")
        public String get() {
            return dao.find(1l).getName();
        }

        @GET
        @Path("/hello")
        public String message() {
            return "hi";
        }
    }

部署后，我手动在表中插入一行。 当我通过浏览器调用get（）方法时，可以看到它正常工作，因为显示了正确的信息。 但是，当我调用put（）方法时，出现异常。

我已经在这个问题上工作了2天了，但是我没有想法。

这是实体和dao类：

AbstractEntity：

@MappedSuperclass
    public abstract class AbstractEntity implements IAbstractEntity {

        private Boolean active;

        @Temporal(TemporalType.DATE)
        private Date creationDate;
        @Temporal(TemporalType.DATE)
        private Date lastModificationDate;

        @Override
        public Boolean getActive() {
            return active;
        }

        @Override
        public void setActive(Boolean active) {
            this.active = active;
        }

        @Override
        public Date getCreationDate() {
            return creationDate;
        }

        @Override
        public void setCreationDate(Date creationDate) {
            this.creationDate = creationDate;
        }

        @Override
        public Date getLastModificationDate() {
            return lastModificationDate;
        }

        @Override
        public void setLastModificationDate(Date lastModificationDate) {
            this.lastModificationDate = lastModificationDate;
        }
    }

实体：

@Entity
    public class Domain extends AbstractEntity implements IDomain {

        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long domainId;

        @ManyToMany(targetEntity = Company.class, mappedBy = "domains")
        private Set companies;

        @OneToMany(targetEntity = Offer.class)
        @JoinColumn(name = "offerId")
        private List offers;

        private String name;

        @Override
        public Long getDomainId() {
            return domainId;
        }

        @Override
        public void setDomainId(Long domainId) {
            this.domainId = domainId;
        }

        @Override
        public Set getCompanies() {
            return companies;
        }

        @Override
        public void setCompanies(Set companies) {
            this.companies = companies;
        }

        @Override
        public List getOffers() {
            return offers;
        }

        @Override
        public void setOffers(List offers) {
            this.offers = offers;
        }

        @Override
        public String getName() {
            return name;
        }

        @Override
        public void setName(String name) {
            this.name = name;
        }
    }

抽象道：

public abstract class AbstractDao {

        private Class entityClass;

        public AbstractDao(Class entityClass) {
            this.entityClass = entityClass;
        }

        protected abstract EntityManager getEntityManager();

        public void create(T entity) {
            getEntityManager().persist(entity);
        }

        public void edit(T entity) {
            getEntityManager().merge(entity);
        }

        public void remove(T entity) {
            getEntityManager().remove(getEntityManager().merge(entity));
        }

        public T find(Object id) {
            return getEntityManager().find(entityClass, id);
        }

        public List findAll() {
            javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
            cq.select(cq.from(entityClass));
            return getEntityManager().createQuery(cq).getResultList();
        }

        public List findRange(int[] range) {
            javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
            cq.select(cq.from(entityClass));
            javax.persistence.Query q = getEntityManager().createQuery(cq);
            q.setMaxResults(range[1] - range[0] + 1);
            q.setFirstResult(range[0]);
            return q.getResultList();
        }

        public int count() {
            javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
            javax.persistence.criteria.Root rt = cq.from(entityClass);
            cq.select(getEntityManager().getCriteriaBuilder().count(rt));
            javax.persistence.Query q = getEntityManager().createQuery(cq);
            `enter code here`return ((Long) q.getSingleResult()).intValue();
        }
    }

DomainDao：

@Stateless
    @LocalBean
    public class DomainDao extends AbstractDao {

        @PersistenceContext(unitName = "rekruterPU")
        private EntityManager em;

        @Override
        protected EntityManager getEntityManager() {
            return em;
        }

        public DomainDao() {
            super(Domain.class);
        }
    }

我不认为问题出在实体或dao类中，因为EntityManager（find（））的至少一种方法有效。 我将不胜感激和帮助。

正如@ kacperb333所建议的那样，标准持久性属性是EclipseLink中此错误的原因。

不使用 ：

<property name="javax.persistence.schema-generation.database.action" value="create"/>

而是使用：

<property name="eclipselink.ddl-generation" value="create-or-extend-tables"/>
