Hibernate查询缓存不起作用

Question

以下是我的代码：

For Each cel In Intersect(Sheets(1).Range("F:F"), Sheets(1).UsedRange)
    If cel.Font.Underline = xlUnderlineStyleSingle Then
        cel.Value = "x" & cel.Value
    End If
Next

For Each cel In Intersect(Sheets(1).Range("H:H"), Sheets(1).UsedRange)
    If cel.Font.Underline = xlUnderlineStyleSingle Then
        cel.Value = "x" & cel.Value
    End If
Next

控制台：

        SessionFactory sf = getSession().getSessionFactory();
        String query = "select r from RefEntity r where r.id in :ids";

        Session s1 = sf.openSession();
        s1.get(RefEntity.class, 1).getValue();
        s1.createQuery(query).setParameterList("ids", Arrays.asList(1, 2)).setCacheable(true).list();

        Session s2 = sf.openSession();
        s2.get(RefEntity.class, 1).getValue();
        s2.createQuery(query).setParameterList("ids", Arrays.asList(1, 2)).list();

二级缓存有效，但我不明白为什么查询缓存没有。谁能解释发生了什么？我会很感激，提前：）

我的实体：

Hibernate: 
    select
        refentity0_.id as id1_6_0_,
        refentity0_.value as value2_6_0_ 
    from
        RefEntity refentity0_ 
    where
        refentity0_.id=?
Hibernate: 
    /* select
        r 
    from
        RefEntity r 
    where
        r.id in :ids */ select
            refentity0_.id as id1_6_,
            refentity0_.value as value2_6_ 
        from
            RefEntity refentity0_ 
        where
            refentity0_.id in (
                ? , ?
            )
Hibernate: 
    /* select
        r 
    from
        RefEntity r 
    where
        r.id in :ids */ select
            refentity0_.id as id1_6_,
            refentity0_.value as value2_6_ 
        from
            RefEntity refentity0_ 
        where
            refentity0_.id in (
                ? , ?
            )

persistence-hidden.xml：

    @SequenceGenerator(name = "ref_seq", sequenceName = "ref_seq", allocationSize = 1)
    @Column(name = "id")
    private Integer id;

    @Column(name = "value")
    private String value;
