Interface TypedIdCassandraRepository<T,ID>

All Superinterfaces:

CassandraRepository<T,ID>, CrudRepository<T,ID>, Repository<T,ID>

Deprecated.

since 2.0, use CassandraRepository.

@NoRepositoryBean
 @Deprecated
public interface TypedIdCassandraRepository<T,ID>
extends CassandraRepository<T,ID>

Cassandra-specific extension of the CrudRepository interface that allows the specification of a type for the identity of the @Table (or @Persistable) type.

If a single column comprises the identity of the entity, then you must do one of two things:

• annotate the field or property in your entity with @PrimaryKey and declare your repository interface to be a subinterface of this interface, specifying the entity type and id type, or
• annotate the field or property in your entity with @PrimaryKeyColumn and declare your repository interface to be a subinterface of MapIdCassandraRepository.

If multiple columns comprise the identity of the entity, then you must employ one of the following two strategies.

• Strategy: use an explicit primary key class
  • Define a primary key class (annotated with @PrimaryKeyClass) that represents your entity's identity.
  • Define your entity to include a field or property of the type of your primary key class, and annotate that field with @PrimaryKey.
  • Define your repository interface to be a subinterface of this interface, including your entity type and your primary key class type.
• Strategy: embed identity fields or properties directly in your entity and use MapIdCassandraRepository
• Define your entity, including a field or property for each column, including those for partition and (optional) cluster columns.
• Annotate each partition & cluster field or property with @PrimaryKeyColumn
• Define your repository interface to be a subinterface of MapIdCassandraRepository, which uses a provided id type, MapId (implemented by BasicMapId).
• Whenever you need a MapId, you can use the static factory method BasicMapId#id() (which is convenient if you import statically) and the builder method MapId.with(String, Object) to easily construct an id.
