mybatis传入list出现报错，请教下大神~看下哪有问题

Question

 这是sql，
 <insert id="batchInsertGroupUser" parameterType="cn.com.landray.kk.server.domain.KKGroupUser">
      INSERT INTO kk_group_user(group_id, user_id, user_count, state, last_update) 
      VALUES 
      <foreach collection="list" item="item" index="index" separator="," > 
          (#{item.groupId}, #{item.userId}, #{item.userCount}, #{item.state}, #{item.lastUpdate})
      </foreach>
 </insert>


 这是报错

 org.apache.ibatis.exceptions.PersistenceException:

Answer 1

 public void testInsertList() throws IOException{
            PageData pd = new PageData();
            List<Video> list= new ArrayList<>();
            Video video = new Video();
            video.setTitle("title1");
            video.setPath("path1");
            list.add(video);
            video = new Video();
            video.setTitle("title2");
            video.setPath("path2");
            list.add(video);
            video = new Video();
            video.setTitle("title3");
            video.setPath("path3");
            list.add(video);
            pd.put("list", list);
            videoService.insertVideoList(pd);

        }

 <insert id="insertVideoList" parameterType="pd">
        INSERT INTO nuansai_video (title,path ) VALUES
         <foreach collection="list" item="item" index="index" separator="," > 
          (#{item.title}, #{item.path})
      </foreach>
    </insert>

经过测试不是sql报错
pd = map
map里放入了 list =【video1,video2,video3】
