  • Constructor Details

    • DynamicEntityGraph

      public DynamicEntityGraph(EntityGraphType type, List<String> attributePaths)
      Parameters:
      attributePaths - The paths of attributes of this EntityGraph. You can refer to direct properties of the entity or nested properties via a property.nestedProperty. e.g. for a product entity: ["brand", "supplier.address"]

  • Method Details

    • loading

      public static DynamicEntityGraph.Builder loading()
      When the javax.persistence.loadgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated according to their specified or default FetchType.

      When the javax.persistence.loadgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated according to their specified or default FetchType.
      Parameters:
      attributePaths - The paths of attributes of this EntityGraph. You can refer to direct properties of the entity or nested properties via a property.nestedProperty. e.g. for a product entity: ["brand", "supplier.address"]

    • buildQueryHint

      public Optional<EntityGraphQueryHint> buildQueryHint(javax.persistence.EntityManager entityManager, Class<?> entityType)
      Specified by:
      buildQueryHint in interface EntityGraph
      Returns:
      A query hint to apply to a query. If empty, the entity graph will be ignored and therefore not applied to the query.
