我正在开发的休息应用程序有一个奇怪的问题。
我创建了实体类以及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。现在我有了这个：
@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，我手动在表格中插入一行。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，我得到一个异常。

我现在已经在这个问题上工作了2天，而且我没有想法。
以下是实体和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;
}
}
摘要道：
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);
}
}
我认为问题不在于实体或dao类，因为至少有一个EntityManager（find（））方法可以工作。我很感激和帮助。
答案 0 :(得分：0)
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"/>
