hibernate中的HQL连接MySQL多张表的问题
假设我数据库有这样两张表 teacher(tid,tname,title) 和 student(sid,sname,age,tid), 将teacher表的ID作为student表的外键,然后在teacher.java和student.java这两个实体类中我要如何添加注解来实现SQL语句中的select * from teacher as t,student as s where t.tid=s.tid .以及我的HQL语句该怎么写?

XML code
<class name="Student">
<id name="id" column="studentId">
<generator class="native"/>
</id>
<many-to-one name="teacher"
column="teacherId"
not-null="true"/>
</class>
<class name="Teacher">
<id name="id" column="teacherId">
<generator class="native"/>
</id>
</class>
