Java 如何在JPA中筛选联接实体

我在下面介绍了这个查询，我只想检索一些由属性名过滤掉的tProducts（比如哪个是活动的，哪个不是布尔值），我该怎么做呢？ 有人能帮忙吗

        value = "SELECT DISTINCT(t) FROM Trfi t " +
            "LEFT JOIN FETCH t.trfiProductCollection tProducts " +
            "LEFT JOIN FETCH tProducts.productModel pModel " +
            "LEFT JOIN FETCH t.trfiPaymentCollection tPayment " +
            "WHERE t.sedId IN (:sessionIds) ",
        countQuery = "SELECT COUNT (DISTINCT t) FROM Trfi t " +
            "JOIN t.trfiProductCollection tProducts " +
            "JOIN tProducts.productModel pModel " +
            "JOIN pModel.provider provider " +
            "JOIN t.trfiPaymentCollection tPayment " +
            "WHERE t.sedId IN (:sessionIds) "
    )
    List<Trfi> getTrfiListBySessionsId(@Param("sessionIds") List<Integer> sessionIds);

value=“从Trfi t中选择不同的（t）”+
“左连接获取t.trfiProductCollection t产品”+
“左连接获取tProducts.productModel pModel”+
“左连接获取t.trfiPaymentCollection tPayment”+
“其中t.sedId位于（：sessionIds）”，
countQuery=“从Trfi t中选择计数（不同的t）”+
“加入t.trfiProductCollection t产品”+
“加入tProducts.productModel pModel”+
“加入pModel.provider提供程序”+
“加入t.trfiPaymentCollection tPayment”+
“其中t.sedId位于（：sessionId）”
)
List getTrfiListBySessionsId（@Param（“sessionIds”）List sessionIds）；

这对你不合适吗

    value = "SELECT DISTINCT(t) FROM Trfi t " +
        "LEFT JOIN FETCH t.trfiProductCollection tProducts " +
        "LEFT JOIN FETCH tProducts.productModel pModel " +
        "LEFT JOIN FETCH t.trfiPaymentCollection tPayment " +
        "WHERE t.sedId IN (:sessionIds) and tProducts.active = :active",
    countQuery = "SELECT COUNT (DISTINCT t) FROM Trfi t " +
        "JOIN t.trfiProductCollection tProducts " +
        "JOIN tProducts.productModel pModel " +
        "JOIN pModel.provider provider " +
        "JOIN t.trfiPaymentCollection tPayment " +
        "WHERE t.sedId IN (:sessionIds) and tProducts.active = :active"
)
List<Trfi> getTrfiListBySessionsId(@Param("sessionIds") List<Integer> sessionIds, @Param("sessionIds") boolean active);

value=“从Trfi t中选择不同的（t）”+
“左连接获取t.trfiProductCollection t产品”+
“左连接获取tProducts.productModel pModel”+
“左连接获取t.trfiPaymentCollection tPayment”+
“其中t.sedId位于（：sessionIds）和tProducts.active=：active”，
countQuery=“从Trfi t中选择计数（不同的t）”+
“加入t.trfiProductCollection t产品”+
“加入tProducts.productModel pModel”+
“加入pModel.provider提供程序”+
“加入t.trfiPaymentCollection tPayment”+
“其中t.sedId在（：sessionIds）中，而tProducts.active=：active”
)
List getTrfiListBySessionsId（@Param（“sessionIds”）List sessionIds，@Param（“sessionIds”）布尔值处于活动状态）；

您是否尝试过这样的“where tProducts.active=FALSE”？tProducts是一个列表，我无法从中访问任何属性，就像这样。。。
