对@Mappedsuperclass上的字段进行JPA查询

Question

我在下面有一个映射的超类：

<uses-permission android:name="android.permission.WAKE_LOCK" tools:node="remove" />

一个实体扩展它：

@MappedSuperclass
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "VERSIONABLE_TYPE")
public class Versionable extends VMAuditedObject implements Serializable,
        Comparable<Versionable> {

    private static final long serialVersionUID = 1L;
    @Basic(optional = false)
    @NotNull
    @Min(0)
    @Column(name = "major_version")
    private int majorVersion;
    @Basic(optional = false)
    @NotNull
    @Min(0)
    @Column(name = "mid_version")
    private int midVersion;
    @Basic(optional = false)
    @NotNull
    @Min(1)
    @Column(name = "minor_version")
    private int minorVersion;
...
}

如何查询Versionable上定义的字段？

public class Project extends Versionable {
....
}

我收到以下错误：

"select from project "
                    + "where major_version=" + p.getMajorVersion()
                    + " and mid_version=" + p.getMidVersion()
                    + " and minor_version=" + p.getMinorVersion();
