为什么 association 关联不出信息，只有Id：

<association property="moveDocDetail" column="MOVE_DOC_DETAIL_ID" javaType="WmsMoveDocDetail"><id column="ID" jdbcType="DECIMAL" property="id" /><association property="product" column="PRODUCT_ID" javaType="BisProduct"><id column="ID" jdbcType="DECIMAL" property="id" /><result column="CODE" jdbcType="VARCHAR" property="code" /><result column="NAME" jdbcType="VARCHAR" property="name" /></association></association>

我这样写有问题吗？
