       // TODO 自动生成 catch 块
       e.printStackTrace();

测试插入作者如图1所示，测试插入主题如图2所示，测试查询主题结果如下：
Hibernate: select topic0_.id as id1_, topic0_.name as name1_, topic0_.user_id as user_id1_, author1_.id as id0_, author1_.name as name0_ from topic topic0_ left outer join author author1_ on topic0_.user_id=author1_.id where topic0_.id=?
jack
生成的sql语句用到了join，查询结果为jack，与期望相符。
