使用association 屬性
column是資料庫表中的字段名,property是映射為對象的屬性名
<resultMap id="BaseResultMap" type="com.bean.Gradetable">
<id column="gid" jdbcType="INTEGER" property="gid" />
<result column="uid" jdbcType="INTEGER" property="uid" />
<result column="math" jdbcType="INTEGER" property="math" />
<result column="chinese" jdbcType="INTEGER" property="chinese" />
<result column="english" jdbcType="INTEGER" property="english" />
<result column="state" jdbcType="INTEGER" property="state" />
<association property="usertable" javaType="com.bean.Usertable">
<result column="uname" jdbcType="VARCHAR" property="uname" />
</association>
</resultMap>
