Mybatis用注解写in查询的实现

@Select("<script>"
        + "SELECT * FROM table WHERE OrderNo IN "
        + "<foreach item='item' index='index' collection='list'      open='(' separator=',' close=')'>"
        + "#{item}"
        + "</foreach>"
        + "</script>")
List<Map<String,Object>> selectdemo(@Param("list") List<String> list);

select * from t_user where user_id in ( '101' , '102' ,'103')

<select id="selectUserByIdList" resultMap="usesInfo">
 SELECT
 *
 from t_user
 WHERE id IN
 <foreach collection="idList" item="id" index="index" open="(" close=")" separator=",">
   #{id}
 </foreach>
</select>

List<UserInfo> selectUserByIdList(@Param("idList")List idList)

List<UserInfo> selectUserByIdList(List idList)

<select id="selectUserByIdList" resultMap="usesInfo">
 SELECT
 *
 from t_user
 WHERE id IN
 <foreach collection="list" item="id" index="index" open="(" close=")" separator=",">
   #{id}
 </foreach>
</select>

List<UserInfo> selectUserByIdList(Long[] idList)

<select id="selectUserByIdList" resultMap="usesInfo">
 SELECT
 *
 from t_user
 WHERE id IN
 <foreach collection="array" item="id" index="index" open="(" close=")" separator=",">
   #{id}
 </foreach>
</select>
