我建了一個實體類girl，但是數據庫里面卻出來了兩張表

Hibernate: drop table if exists girl

Hibernate: drop table if exists hibernate_sequence

Hibernate: create table girl (id integer not null, age integer, cup_size varchar(255), primary key (id)) engine=MyISAM

Hibernate: create table hibernate_sequence (next_val bigint) engine=MyISAM

Hibernate: insert into hibernate_sequence values ( 1 )
