注意：

sql语句创建的表要和实体bean对应。否则会出错。

create table Seat (id bigint not null auto_increment, booked bit not null, seat_id bigint, zhibin varchar(25),  primary key (id))
create table seat_type (id bigint not null auto_increment, description varchar(25) not null, position varchar(255), price integer not null, quantity integer not null, primary key (id))
alter table Seat add constraint FK9pohag9bkh1suwck1bxtr7cys foreign key (seat_id) references seat_type (id)

sql文件可以放在meta-inf里面：

<property name="javax.persistence.sql-load-script-source" value="META-INF/data.sql"/>

真实路径要在：src/main/resources/META-INF/create.sql

./drop.sql是widlfly从哪里运行的当前目录。
