Mybatis 返回List 报The error occurred while handling results

<select id="checkPass" parameterType="java.util.Map" resultType="java.util.List">
	 	select user_id from t_user_info tcc
	 	<trim prefix="where" prefixOverrides="and|or">
		 	 <if test="cpIds!=null">
		 		 and tcc.user_id in
		 		 <foreach collection="cpIds" index="index" item="cpId" open="(" separator="," close=")">
		 		    #{cpId}
		 		 </foreach>
		 	 </if>
	 	 </trim>
	 	 group by user_id
	 </select>

预期是想返回user_id的集合，所以resultType用的是java.util.List

执行报错：
Caused by: org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.lang.UnsupportedOperationException
### The error may exist in 
### The error occurred while handling results
### SQL: select user_id from t_user_info tcc     where  tcc.user_id in       (          ?       )      group by user_id

查阅List相关返回需要需设置List中对应的属性就可以
修改为如下执行正常

<select id="checkPass" parameterType="java.util.Map" resultType="java.util.Long">
	 	select user_id from t_user_info tcc
	 	<trim prefix="where" prefixOverrides="and|or">
		 	 <if test="cpIds!=null">
		 		 and tcc.user_id in
		 		 <foreach collection="cpIds" index="index" item="cpId" open="(" separator="," close=")">
		 		    #{cpId}
		 		 </foreach>
		 	 </if>
	 	 </trim>
	 	 group by user_id
	 </select>

resultType是sql映射文件中定义返回值类型，返回值有基本类型，对象类型，List类型，Map类型等。现总结一下再解释

总结：
resultType:

1、基本类型 ：resultType=基本类型

2、List类型： resultType=List中元素的类型
