Annotation Type JoinTable


@Target(value={METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface JoinTable

This annotation is used in the mapping of associations. It is specified on the owning side of a many-to-many association, or in a unidirectional one-to-many association. If the JoinTable annotation is missing, the default values of the annotation elements apply. The name of the join table is assumed to be the table names of the associated primary tables concatenated together (owning side first) using an underscore.
