错误问题：collection查询一对多分页统计数量是统计详情的条数
解决思路：collection分成两次查询
<resultMap id="resultMap" type="com.zgdd.business.vo.UserVO">
<result column="id" property="id"/>
<result column="create_time" property="createTime"/>
<result column="update_time" property="updateTime"/>
<result column="is_deleted" property="isDeleted"/>
<result column="user_name" property="userName"/>
<result column="pass_word" property="passWord"/>
<result column="phone" property="phone"/>
<result column="remarks" property="remarks"/>
<result column="sign_time" property="signTime"/>
<collection property="list" select="selectUserDetail" column="id" javaType="list" ofType="com.zgdd.business.vo.UserDetailVO">
<id property="id" column="id"></id>
<result column="user_id" property="userId"></result>
<result column="detail_name" property="detailName"></result>
</collection>
</resultMap>
<select id="selectUserPage" resultMap="resultMap">
select * form user where is_deleted = 0
</select>
<select id="selectUserPage" resultType="com.zgdd.business.vo.UserDetailVO">
select * form user_detail where is_deleted = 0 and user_id = #{id}
</select>
