Hibernate Criteria - 带有子集的resultTransformer

我在有多个孩子的桌子上遇到Hibernate Criteria问题。

这是我的标准：

crit = session.createCriteria(PrescRicette.class)
            .createAlias("prescEpisodi", "episodi", Criteria.LEFT_JOIN)
            .createAlias("prescEsenzioni", "prescEsenzioni", Criteria.LEFT_JOIN)
            .createAlias("prescRicetteAmb", "ricetteAmb", Criteria.LEFT_JOIN)
            .createAlias("prescRicetteFarma", "ricetteFarma", Criteria.LEFT_JOIN)
            .createAlias("prescRicettePrescrizioni", "ricettePrescrizioni", Criteria.LEFT_JOIN)
            .createAlias("prescIdentificativiRicette", "prescIdentificativiRicette", Criteria.LEFT_JOIN)
            .createAlias("episodi.prescAssistiti", "assistito", Criteria.LEFT_JOIN)
            .createAlias("ricetteAmb.prescFascePriorita", "fascePriorita", Criteria.LEFT_JOIN)
            .createAlias("ricetteFarma.prescNoteCuf", "noteCuf", Criteria.LEFT_JOIN)
            .createAlias("ricettePrescrizioni.prescPrescrizioni", "prescrizioni", Criteria.LEFT_JOIN)
            .createAlias("prescrizioni.prescPrestazioni", "prestazioni", Criteria.LEFT_JOIN)
            .createAlias("prestazioni.prescBranche", "branche", Criteria.LEFT_JOIN)
            .createAlias("prestazioni.prescPrestazioni030", "prestazioni030", Criteria.LEFT_JOIN)
            .createAlias("prescrizioni.prescFarmaci", "farmaci", Criteria.LEFT_JOIN)
            .createAlias("farmaci.prescFarmaGruppiEquiv", "farmaciGruppiEquiv", Criteria.LEFT_JOIN)
            .createAlias("farmaci.prescFarmaci030", "farmaci030", Criteria.LEFT_JOIN)
            .createAlias("farmaciGruppiEquiv.prescGruppiEquivalenza", "gruppiEquiv", Criteria.LEFT_JOIN)
            .createAlias("prescEsenzioni.prescTipiEsenzioni", "prescTipiEsenzioni", Criteria.LEFT_JOIN)
            .add(Restrictions.eq("assistito.idPazAnaPaz", idPaz))
            .add(Restrictions.isNotEmpty("prescIdentificativiRicette"))
            .addOrder(Order.desc("dataEmissione"))
            .setResultTransformer(new AliasToBeanResultTransformer(PrescRicette.class));

    ricetteDB = crit.list();

我之所以这样做是因为出于性能原因，我需要以非惰性模式获取数据，并在表之间进行LEFT JOIN。

这是错误：

[WARN] BaseCallMarshaller - --Erroring: batchId[25] message[org.hibernate.PropertyNotFoundException: Could not find setter for prescTipiEsenzioni on class org.oshc.hibernate.modules.gestioneRicette.PrescRicette]

现在，问题是我不希望在PrescRicette上设置实体prescTipiRicette，而且我无法在标准上找到错误。

如果没有resultTransformer字段映射就好了，但是为每个子节点复制了根实体。 使用.setResultTransformer（Criteria.DISTINCT_ROOT_ENTITY），根元素不会被复制，但每个根只有一个子元素。

这个实体太多了，无法复制和粘贴在这个问题中，所以在一些更多的片段中只需要问一下，我会添加它们。

提前致谢， 马蒂亚

1 个答案:

答案 0 :(得分：0)

代码：

createAlias("prescEsenzioni.prescTipiEsenzioni", "prescTipiEsenzioni", Criteria.LEFT_JOIN)

例外：

org.hibernate.PropertyNotFoundException: Could not find setter for prescTipiEsenzioni on class org.oshc.hibernate.modules.gestioneRicette.PrescRicette

AliasToBeanResultTransformer正在尝试将地图prescTipiEsenzioni转换为您的类org.oshc.hibernate.modules.gestioneRicette.PrescRicette但在此过程中失败，因为它缺少prescTipiEsenzioni的setter。

您是否可以检查PrescRicette是否具有prescTipiEsenzioni属性和相应的字段/设置者？
