    • mappedBy

      String mappedBy
      The property that owns the association. Required unless the relationship is unidirectional.

      Once `mappedBy` is specified, the current property is just a mirror of the property in the opposite entity that truly owns this association. Do not use `@JoinColumn` or `@JoinTable` for association mapping.

      Unlike JPA, for bidirectional associations, Jimmer allows developers to arbitrarily decide which side to be `mappedBy` side, which does not affect save behaviors.

      返回:
      A property name of associated entity.
      默认值:
      ""

    • orderedProps

      OrderedProp[] orderedProps
      This configuration is used by object fetcher.

      Object fetcher supports property-level filter so that the order by associated objects can be dynamically controlled. However, fetching association property with property-level filter ignores the association cache

      In order to resolve this problem, you can specify the default order for associated objects

      返回:
      The ordered properties of associated objects
      默认值:
      {}
