    <!--useGeneratedKeys="true"表明使用数据库自动生成的主键，
      keyColumn="id"指定Student表中主键列，keyProperty="id"
            表明当插入记录后，会把数据库生成的主键值设置到Student对象
            的id属性中，也就是说，它指定与Student表中的主键列对应的
      Student实体类中的属性是id这个属性-->
    <insert id="add" useGeneratedKeys="true" keyColumn="id"
        keyProperty="id" 
        parameterType="com.abc.domain.Student">
        insert into student(name, gender, major, grade)
        values(#{name}, #{gender}, #{major}, #{grade})
    </insert>
