Hibernate Spring数据jpa如何重用@NamedEntityGraph？

如果我希望

Address

的实体图使用子图中现有的

CITY\u BASIC

或

CITY\u DETAILS

实体图，我该怎么办？

当然，使用原始图的名称。它只能在同一类中调用。当然，使用原始图的名称。它只能在同一类中调用。

@NamedEntityGraphs({
        @NamedEntityGraph(name = CITY_BASIC, attributeNodes = {
                @NamedAttributeNode("state"),
                @NamedAttributeNode("country")
        }),
        @NamedEntityGraph(name = CITY_DETAILS, attributeNodes = {
                @NamedAttributeNode("state"),
                @NamedAttributeNode("country"),
                @NamedAttributeNode(value = "suburbs", subgraph = "basic")
        },
                subgraphs = @NamedSubgraph(name = CITY_BASIC, attributeNodes = {
                        @NamedAttributeNode("state"),
                        @NamedAttributeNode("country")
                }))
})
public class City {
  private String name;
  private State state;
  private Set<City> suburbs;
}

public class Address {
  private String street;
  private City city;
}
