Jakarta ee Java-EE6：为什么查询抛出org.eclipse.persistence.exceptions.QueryException？

我的项目具有以下配置：

• MySQL 5.5数据库服务器
• 玻璃鱼3.1.2.2
• Eclipselink 2.3.2作为JPA提供商
• Java SE独立客户端通过JNDI查找和 远程接口

我使用静态编织来惰性地获取重关系（由负载组完成）

我有以下实体来序列化文件并将其存储到数据库：

@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my document facade中包含管理功能（持久化、修改、删除和查询）的列表：

现在我得到了以下异常：

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

下面是完整的堆栈跟踪：

非常感谢您的帮助！非常感谢

我希望我没有误解你的问题

我认为您应该能够使用em.find获取您的实体

long docId = 10;
Document doc = em.find(Document.class, docId);

或者，如果它不是Id，那么这会更好：

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

TypedQuery query=em.createQuery（“从文档d中选择d，其中d.id=：id”，Document.class”）.setParameter（“id”，docId）；

我改变了

@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)

到

现在它工作得很好。它与继承的@Id有冲突。JPA使用自动生成的子类的fetch组，即使在调用超类的对象实例时也是如此。。。可能是eclipse链接中的错误。

你好，阿克塞尔。非常感谢你的建议。这并不能解决问题，因为我懒散地获取实体，因此需要定义加载组/获取组。我认为这不适用于em.find（）。

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

@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)

@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
