java - JEE、eclipselink、glassfish4.0无法持久化实体

Question

我正在开发的休息应用程序有一个奇怪的问题。

我创建了实体类和 dao 类来管理它们。现在，当我将应用程序部署到服务器时，我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，我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。

我已经研究这个问题两天了，但我没有任何想法。

以下是实体和 dao 类:

抽象实体:

    @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 的至少一种方法(find())可以工作。我将不胜感激并提供帮助。

正如 @kacperb333 所建议的，标准持久性属性是 EclipseLink 中出现此错误的原因。

不要使用:

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

改为使用:

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