map的key转换格式 map＜long,string＞ 转换为map＜string,string＞

Map<Long, String> cVCardMap = userCCardComponent2.getUserCCardWithExpV2(UserCCardDto.class, liepinIdList, EnumResumeViewScene.RECOMMEND.getCode(), usercExpectFindBean, idRole, false); Map<String, String> allCVCardMap = cVCardMap.entrySet().stream() .collect(Collectors.toMap(e -> String.valueOf(e.getKey()), Map.Entry::getValue));
