Ambiguous method overloading for method java.lang.Long#minus. Cannot resolve which method to invoke

Ambiguous method overloading for method java.lang.Long#minus. Cannot resolve which method to invoke 项目上线，第一次成功，第二次就失败。记录下自勉，希望可以一直成长，一直努力！

Long lastUpdate = serviceResult.result?.lastUpdate if (now - lastUpdate > TimeUtils.TIME_1_HOURS_MILLISECOND) { accessToken = getDingAccessToken(getSuiteTicket(corpId), corpId) if (StringUtils.isNotBlank(accessToken)) { //放入缓存中 cacheService.dingAccessToken.put(tokenKey, ServiceResult.success([accessToken: accessToken, lastuUpdate: now])) } }

获取token的代码，出现这错误就很难受，导致所有都出错了。存的时候多打了一个"u"–lastuUpdate 在缓存中拿的时候 ”lastUpdate“就一直报这个错误，相当于

Long a = 2 Long b = null Long c = a - b

尊重每一行代码，每天进步一点
