SSM框架中Mybatis向映射文件（XML）的<insert>元素传入多个数组参数的问题

void insertByArr(@Param("actorid") int actorid, @Param("garry") String[] group, @Param("narry") String[] node);

<insert id="insertByArr" useGeneratedKeys="true">
insert into role_menu (roleid,menuid)values
<if test="garry != null">
<foreach collection="garry" item="item"
index="index" separator=",">
(#{actorid},#{item})
</foreach>
</if>
<if test="garry !=null and narry != null">
,
</if>
<if test="narry != null">
<foreach collection="narry" item="item"
index="index"  separator=",">
(#{actorid},#{item})
</foreach>
</if>
</insert>
