hibernate - 在休眠中带有集合名称的下划线

Question

Hibernate: insert into college (name, college_id) values (?, ?)
Hibernate: insert into student (college_id, student_name, student_id) values (?, ?, ?)
Hibernate: insert into student (college_id, student_name, student_id) values (?, ?, ?)
Hibernate: select college0_.college_id as college1_1_0_, college0_.name as name1_0_ from college college0_ where college0_.college_id=?
Hibernate: select students0_.college_id as college2_1_0_, students0_.student_name as student3_0_ from student students0_ where students0_.college_id=?

我是hibernate的新手。从mysql db的表中选择一行时，我得到了上面的控制台语句。在那（college0_.college_id as college1_1_0_）什么是college0，college1_1_0_。我不明白什么是1_1_0和表名连接为 0 的大学。

任何人解释我。谢谢
