selectList()只能传递一个参数，但实际所需参数既要包含String类型，又要包含List类型时的处理方法：

List<String> list_3 = new ArrayList<String>();
Map<String, Object> map2 = new HashMap<String, Object>();

list.add("1");
list.add("2");
map2.put("list", list); //网址id

map2.put("siteTag", "0");//网址类型

public List<SysWeb> getSysInfo(Map<String, Object> map2) {
    
    
　　return getSqlSession().selectList("sysweb.getSysInfo", map2);
}

<select id="getSysInfo" parameterType="java.util.Map" resultType="SysWeb">
　　select t.sysSiteId, t.siteName, t1.mzNum as siteTagNum, t1.mzName as siteTag, t.url, t.iconPath
   from TD_WEB_SYSSITE t
   left join TD_MZ_MZDY t1 on t1.mzNum = t.siteTag and t1.mzType = 10
   WHERE t.siteTag = #{siteTag } 
   and t.sysSiteId not in 
   <foreach collection="list" item="item" index="index" open="(" close=")" separator=",">
       #{item}
   </foreach>
 </select>
