Package org.hibernate.annotations

Package containing all Hibernate's specific annotations.

Basic value mapping

Hibernate supports 2 approaches to defining a mapping strategy for basic values:

• A "compositional" approach using a combination of the following influencers for various parts of mapping
  • JavaType
  • JdbcType
  • JdbcTypeCode
  • Mutability
  • AttributeConverter / Convert
  • Lob
  • Enumerated
  • Temporal
  • Nationalized
  Note that JavaType, JdbcType, JdbcTypeCode and Mutability all have specialized forms for the various model parts such as map-key, list-index, (id-bag) collection-id, etc.
• Contracted via the UserType interface and specified using Type. As with the compositional approach, there are model-part specific annotations for specifying custom-types as well.

These 2 approaches are not intended to be mixed. Specifying a custom-type takes precedence over the compositional approach. Though the compositional approach is recommended, both forms are fully supported. See the user-guide for a more in-depth discussion
