Annotation Type SecondaryTable


@Target(value=TYPE)
@Retention(value=RUNTIME)
public @interface SecondaryTable

This annotation is used to specify a secondary table for the annotated entity class. Specifying one or more secondary tables indicates that the data for the entity class is stored across multiple tables. If no SecondaryTable annotation is specified, it is assumed that all persistent fields or properties of the entity are mapped to the primary table. If no primary key join columns are specified, the join columns are assumed to reference the primary key columns of the primary table, and have the same names and types as the referenced primary key columns of the primary table.
