mybtis异常

 Cause: java.lang.IllegalStateException: Type handler was null on parameter mapping for property '__frch_uid_0'.  It was either not specified and/or could not be found for the javaType / jdbcType combination specified.

这个在

 select * from table  where id in 

<foreach collection="yourList" index="index" item="item" open="(" separator="," close=")">
               #{item}              </foreach> 

你的这个 yourList  如果传递过来的是 对象的集合。那么 你应该获取的是 item.id否则就报错 

 修改为  #{item.id}

或者你直接把 id查出来放到集合中。那么久直接用了。不会报错
