关于Hibernate many-to-one 中的inverse

假设存在两个实体Teacher和Student
且teacher和student是one-to-many的关系。


在配置双向关联时，那么对inverse的使用， 会存在如下情况：

1、

Teacher.hbm.xml

		<set name="students" 
			inverse="true">
			<key column="teacher_id" not-null="true">
			</key>
			<one-to-many class="Student"/>
		</set>

				student1.setTeacher(teacher);
				student2.setTeacher(teacher);
				

				
				session.save(teacher);
				session.save(student1);
				session.save(student2);

产生的sql

Hibernate: 
    insert 
    into
        t_teacher
        (c_name) 
    values
        (?)
Hibernate: 
    insert 
    into
        t_student
        (c_name, c_teacher_id) 
    values
        (?, ?)
Hibernate: 
    insert 
    into
        t_student
        (c_name, c_teacher_id) 
    values
        (?, ?)
