ibatis批量插入oracle数据库

<insert id="batchInsert" parameterClass="java.util.List">
	INSERT INTO SYS_ROLE_MENU(
	ROLE_ID,	
	MENU_ID	
		)
	SELECT A.*
	FROM (
		<iterate  conjunction ="union all" >
		SELECT
			#list[].key# as ROLE_ID,
			#list[].value# as MENU_ID
		from dual
		</iterate >
	  ) A
	</insert>
