mybatis处理集合和数组

1.     如果传入的参数类型是一个List的时候，collection属性值为list

2.     如果传入的参数类型是一个array数组的时候，collection的属性值为array

 

	<delete id="deleteMul" parameterType="java.util.List">
		delete from time_rule where id in (
		<foreach collection="array" item="item" index="index"  open="" close="" separator=","> <!-- property="id" -->
			#{item}
		</foreach>
		);
	</delete>
