Java-EE6：为什么查询会抛出org.eclipse.persistence.exceptions.QueryException？

时间：2012-12-05 14:20:01

标签： java-ee exception glassfish-3

我的项目具有以下配置：

  • MySQL 5.5数据库服务器
  • Glassfish 3.1.2.2
  • Eclipselink 2.3.2作为JPA提供者
  • 通过JNDI查找和连接到Glassfish的Java SE独立客户端 远程接口

我使用静态编织来懒惰地获取重关系（由加载组完成）。

我有以下实体来序列化和存储文件到数据库：

@Entity
@Table(name = "Document")
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
public class Document implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    protected Long id;

    @Column(length = 128)
    protected String description;

    @Lob
    @Basic(optional=false, fetch=FetchType.LAZY)
    protected byte[] content;

    @Transient
    protected transient File file;

    public Document() { }

    // getters and setters ...

}

以下是我的文档外观中的coutout，其中包含管理功能（持久，修改，删除和查询）：

@Override
@RolesAllowed("User")
public Document queryById(Long id, LoadGroup group) {
    TypedQuery<Document> query = em.createQuery("SELECT d FROM Document d WHERE d.id = "+id, Document.class);
    if(group!=null) {
        query.setHint(QueryHints.LOAD_GROUP, group);
    }
    try {
        return query.getSingleResult();
    } catch(NoResultException ex) {
        return null;
    }
}

这是我在独立客户端上调用查询的方法：

DocumentFacadeRemote documentFacade = (DocumentFacadeRemote)ctx.lookup("java:global/LawSuiteEE/LawSuiteEE-ejb/DocumentFacade!ch.lawsuite.control.DocumentFacadeRemote");

LoadGroup group = new LoadGroup();
group.addAttribute("content");

Document document = documentFacade.queryById(new Long(1), group);

现在我收到以下异常：

Exception Description: The parameter name [ID] in the query's selection criteria does not match any parameter name defined in the query.

这里是完整的堆栈跟踪：

答案 0 :(得分：1)

我希望我不会误解你的问题。

我认为您应该可以使用em.find

来获取您的实体 
long docId = 10;
Document doc = em.find(Document.class, docId);

或者如果它不是Id，这会更好：

TypedQuery<Document> query = em.createQuery("SELECT d FROM Document d WHERE d.id = :id", Document.class).setParameter("id",docId);

答案 1 :(得分：1)

我改变了

@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)

到

@Inheritance(strategy=InheritanceType.SINGLE_TABLE)

现在它工作得很好。它以某种方式与继承的@Id's发生冲突。即使在超类的对象实例上调用查询时，JPA也使用了子类的自动生成的获取组...可能是eclipse-link中的错误。
