График сущности JPA Spring Data, выбирающий все поля

Question

Я пытаюсь разработать API поиска, для которого мне не нужно выбирать каждый столбец в таблицах. Могут быть некоторые критерии для фильтрации, и я использую для этого CriteriaBuilder. Затем я определил NamedEntityGraph и его подграфы для выбора нужных мне столбцов c. Но я что-то упускаю и не могу найти, что это такое. Потому что всякий раз, когда я выполняю запрос, он выбирает все значения объекта.

@NamedEntityGraph(name = "graph.Bill",
    attributeNodes = {
        @NamedAttributeNode(value = "id"),
        @NamedAttributeNode(value = "invoiceName"),
        @NamedAttributeNode(value = "creationDate"),
        @NamedAttributeNode(value = "products", subgraph = "subGraph.Product"),
        @NamedAttributeNode(value = "customer", subgraph = "subGraph.Customer"),
        @NamedAttributeNode(value = "user", subgraph = "subGraph.User")
    },
    subgraphs = {
        @NamedSubgraph(
            name = "subGraph.Product",
            attributeNodes = {
                @NamedAttributeNode(value = "quantity"),
                @NamedAttributeNode(value = "taxPercentage"),
                @NamedAttributeNode(value = "rate")
            }
        ),
        @NamedSubgraph(
            name = "subGraph.Customer",
            attributeNodes = {
                @NamedAttributeNode(value = "name")
            }
        ),
        @NamedSubgraph(
            name = "subGraph.User",
            attributeNodes = {
                @NamedAttributeNode(value = "name")
            }
        )
    }
