如何使用2个主键字段hibernate创建表

Question

我正在尝试使用复合主键创建tabel实体。 所以我尝试使用所有主键创建SELECT t.*, r.* FROM t INNER JOIN r ON t._id = r.r_identifier WHERE r.r_date = (SELECT MAX(r2.r_date) FROM r r2 WHERE r.r_identifier = r2.r_identifier ); 类，并在表示主键的字段上使用@Embeddable。但我得到这个错误：

@EmbeddedId

我试图按照这个link蝙蝠注意工作 我做错了什么？

这是我的代码

DocEntity

Caused by: org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

DocID

@Entity(name = "doc")
@Table(name = "doc")
public class DocEntity extends baseDataBase implements Serializable
{
    private static final long serialVersionUID = 1L;


    @EmbeddedId
    private DocID docID;

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "DocID")
    @JsonProperty
    @NotEmpty
    private short id;

    @Column(name = "DocDescription")
    @JsonProperty
    @NotEmpty
    private String docDescription;

    @Column(name = "DocPath")
    @JsonProperty
    @NotEmpty
    private String docPath;

     // getters, setters ,equals, hashCode
}

我做错了什么？
