其中一个实体参数组装成key，
可能还需要比较该集合中实体某个参数是否一致
并使caseid一致

String key = Id +"-"+ Name+"-"+testTime;
if(detailMap.containsKey(key)){
    UatBugCaseHouseDetail detail_onty=（UatBugCaseHouseDetail)detailMap.get(key);
    if(detail_only.getStripLineName().equals(stripLineName)){
        detail.setCaseId(detait_only.getCaseId());
        detaitList.add(detaiu);
        detailMap.put(key,detail);
    }else {
        uList.add(u);
        detaiuList.add(detait);
        detailMap.put(key,detail);
    }
else{
    uList.add(u);
    detaiLList.add(detaiu);
    detaiuMap.put(key,detail);
}
