请帮忙MyBatis sqlSession.selectList

Question

mybatisjavahashmap

Answer 1

把数据放进数组比如List<String> members，xml配置中SELECT * FROM MEMBER WHERE MEMBER_ID IN
<iterate property="members" open="(" close=")" conjunction=",">  
#members[]#  
</iterate> 

Answer 2

你试试用${members}
#{members}会被myBatis处理，而${members}则原封不动

Answer 3

谢谢各位，问题解决了 <foreach item="members" index="index" collection="list" 
 open="(" separator="," close=")"> 
 #{members} 
 </foreach>
