mybatis 传入多个list

mybatis传入多个list集合做参数，很多文章的介绍都是不能实现的，千篇一律的复制，有很大的误导性，这里说一下如何实现：

这里建议你传递对象过来，比如Person对象，里面加入List list1; List list2;….这样，把对象传到mapper.xml中时，取法如下：

dao.java

List<User> find(@Param("person")Person person,@Param("name")String name);

mapper.xml

<if test="person.list1 != null">
      and id in
      <foreach collection="person.list1" index="index" item="item" open="(" separator="," close=")">
        '${item}'
      </foreach>
    </if>
       <if test="person.list2 != null">
      and id in
      <foreach collection="person.list2" index="index" item="item" open="(" separator="," close=")">
        '${item}'
      </foreach>
    </if>

记录

<select id="getEidList" resultType="java.lang.String">
    SELECT efe.eid from ent_file_emergent_industry efe,ent_file ef
      where 1 =1
      and efe.eid = ef.eid
      and efe.code in (SELECT code from dict_emergent_industry where type = 2 and remark in (
        <foreach collection="param.customRemarkOrCodeList" index="index" item="item" open="(" separator="," close=")" >
          '${item}'
        </foreach>
      ))
      and ef.plat_from = '${param.platFrom}'
      and ef.delete_flag = 0
  </select>
