询问一个关于mybatis in多条件查询的问题

Question

这是错误：

  SQL: SELECT node_id FROM access_layer where member_id IN        (                  ?       ,                 ?       ,                 ?       ,                 ?       ,                 ?       ,                 ?       )
### Cause: java.lang.UnsupportedOperationException] with root cause

controller的语句：

 List<String> sonNodes = accessService.selectByIn(sons);

mapper.xml：

 <select id="selectByIn" parameterType="java.util.List" resultType="java.util.List">
        SELECT node_id FROM access_layer where member_id IN 
     <foreach collection="list" item="member_id" index="index" open="(" separator="," close=")">
               #{member_id}
     </foreach>
    </select>

dao：

 public List<String> selectByIn(List<String> member_id);

Answer 1

resultType="java.util.List" 直接string 就好了
