未超过1000时的写法：
select * from tbl_temp where id in <foreach item="item" index="index" collection="ids" open="(" separator="," close=")"> #{item} </foreach>
select * from tbl_temp where id in (1,2,3)
超过1000时的写法：
select * from tbl_temp where <foreach item="item" index="index" collection="ids" open="(" separator="or" close=")"> id in #{item} </foreach>
select * from tbl_temp where (id in 1 or id in 2 or id in 3)
