三、二级标签实体类声明:

<id column="uuid" property="uuid" jdbcType="VARCHAR" />
<result column="name" property="name" jdbcType="VARCHAR" />
<result column="type" property="type" jdbcType="VARCHAR" />
<result column="status" property="status" jdbcType="VARCHAR" />
<collection property="otherDemoList" ofType="com.xxx.model.OtherDemo">
<id column="uuid" jdbcType="VARCHAR" property="uuid" />
<result column="name" property="name" jdbcType="VARCHAR" />
</collection>
</resultMap>
