Java JPA在添加ORDERBY子句时忽略左外部联接注释

我有一个实体，它看起来是这样的：

@Entity
@Table(name = "LOG_ENTRY")
public class LogEntry implements Serializable {

...
    @JoinFetch(JoinFetchType.OUTER)
    @ManyToOne
    @JoinColumn(name = "SERVER_ID")
    private Server server;
...
}


@Entity
@Table(name = "SERVER")
public class Server extends implements Serializable {
...
    @Column(name = "NAME")
    private String name;
...
}

当我以以下方式构造查询时：

CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<LogEntry> criteria = builder.createQuery(LogEntry.class);
Root<LogEntry> root = criteria.from(LogEntry.class);

但当我以以下方式将orderBy添加到条件中时：

CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<LogEntry> criteria = builder.createQuery(LogEntry.class);
Root<LogEntry> root = criteria.from(LogEntry.class);
criteria.orderBy(builder.desc(root.get("server.name")));

我使用的是eclipselink 2.3.3（您可能会注意到，因为我在实体中使用了org.eclipse.persistence.annotations.JoinFetch）

有什么办法解决这个问题吗？ 切换到Hibernate会使它正常工作吗

尝试

@ManyToOne（可选=true）

CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<LogEntry> criteria = builder.createQuery(LogEntry.class);
Root<LogEntry> root = criteria.from(LogEntry.class);
criteria.orderBy(builder.desc(root.get("server.name")));

SELECT t0.NAME FROM SERVER t0, LOG_ENTRY t1 WHERE (t0.ID = t1.SERVER_ID) ORDER BY t0.NAME DESC
