谢谢，问题解决了，现在附上源码，希望帮到后面的朋友

    List arrayList= new ArrayList();
public List<Map<String, Object>> selectfdbsListMaps(String fdbs) {
    if (arrayList != null) {
        arrayList.removeAll(arrayList);
    }
    Map<String, Object> kdLxbMapTow = null;
    List<Map<String, Object>> kdLxbMap = this.jcIPdao.selectfdbsListMaps(fdbs);
    List<Map<String, Object>> queryList = this.jcIPdao.selectAllIpList();
    if (!fdbs.equals("")) {
        kdLxbMapTow = this.jcIPdao.selectcstc(fdbs);
        for (Map<String, Object> maps : kdLxbMap) {
            maps.putAll(kdLxbMapTow);
        }
        arrayList.addAll(kdLxbMap);
        return arrayList;
    } else {
        for (Map<String, Object> maps1 : queryList) {
                kdLxbMapTow = this.jcIPdao.selectcstc(maps1.get("fdbs").toString());
                maps1.putAll(kdLxbMapTow);
        }
        arrayList.addAll(queryList);
        return arrayList;
    }

}
