sql is :
<select id="insertByMarkPins" parameterType="List">
INSERT INTO cv_task_mark_user (
team_id ,
task_id ,
pin,
creator,
created,
deleted
)
VALUES
<foreach collection="list" index="index" item="item" separator=",">
(#{item.teamId},#{item.taskId},#{item.pin},#{item.creator},now(),0)
</foreach>
</select>
parameterType="List" 参数是一个集合List
