ibatis自带批量删除

ibatis普通删除：

<delete id = "delete" parameterType = "test">      <![CDATA[         delete from tests where id = #id#      ]]>  </delete>

ibatis自带的批量删除：

<delete id = "delete" parameterType = "java.util.List">      <![CDATA[         delete from tests where id in      ]]>      <foreach collection="list" item = "list" open="(" separator="," close=")">#list.id#       </foreach>  </delete> 

collection里表示类型，这里是list，还可以是array。list不用管，相当于一个变量。
