1快捷鍵 ctrl shift f9 熱部署 idea debug模式

springcloud 踩坑日誌

2經過zuul 網關上傳文件 會出現中文亂碼，須要在uri網關前面加上zuul

3 feignclient調用 降級 異常日誌處理
@Component
static class ScheduleServiceHystrixClientFallbackFactory implements FallbackFactory<IScheduleServiceFeignClient> {
@Override
public IScheduleServiceFeignClient create(Throwable cause) {
//log不要寫在這裏 不然啓動的時候會報異常信息
return new IScheduleServiceFeignClient() {
@Override
public ServiceResultDTO saveSchedule(OpenScheduleDto openScheduleDto) {
logger.error("IScheduleServiceFeignClient 調用SERVICE-BASE服務失敗{}", cause); //不要寫在匿名內部內以前， 不然啓動的時候會報異常信息，可是不影響啓動
return ServiceResultDTO.build("ex", "調用服務進行待辦推送服務出錯!");

}
}

@EnableFeignClients(basePackages = {"com.qiye.ext.service","com.qiye.base.service"}) 這時候只掃描配置了包下@feigin註解上相關包的接口或類

//關閉 或kill -9 進程Id 經過pkill -9 redis殺死reids 進程以後，從新啓動各個節點，集羣自動建立成功（殺死以前的集羣狀態）
注意：前提是不要清空nodes.conf文件

經測試 spring定時器@Scheduled(cron=） 在集羣模式下，運行代碼內容時間起點是不一致的，有微小差距，微妙級別，致使定時器重複執行，後面
又趨於正常（多是cpu是單核的吧，測試是在同一臺機器
開某個服務部署2個節點），因此可能存在定時器重複執行，建議在定時器裏處理業務代碼的時候，休眠0.5毫秒或1秒，若是業務邏輯處理很快
再加上服務器存在的時間差，致使定時器重複執行。
