c# - async/await - 何时返回 Task 与 void?

在什么场景下使用publicasyncTaskAsyncMethod(intnum)代替publicasyncvoidAsyncMethod(intnum)我能想到的唯一场景是,如果您需要任务能够跟踪其进度。另外,在下面的方法中,async和await关键字是不是就不需要了?publicstaticasyncvoidAsyncMethod2(intnum){awaitTask.Factory.StartNew(()=>Thread.Sleep(num));} 最佳答案 通常,您会想要返回一个Task。主要的异常(exception)

异常 :Unexpected error occurred in scheduled task 。 Spring Boot定时任务调度注解@scheduled

         前言:@Scheduled注解是SpringBoot提供的用于定时任务控制的注解,主要用于控制任务在某个指定时间执行,或者每隔一段时间执行    异常:Unexpectederroroccurredinscheduledtask:计划任务发生意外错误这个bug是偶然一次遇见的,当时觉得这个描述很简单,肯定是和定时任务跑不了关系 具体原因:        因为@Scheduled注解执行级别高于spring@Resource资源注入的级别,所以在服务启动时会优先进行调度操作,但这个时候spring还没有将容器中注入bean但是你实现定时调度又需要,所以导致自动注入失败>=

pip安装解决报错:WARNING: Running pip as the ‘root‘ user can result in broken permissions and conflicting

当我们使用pip安装库的时候和一些模块的时候,经常会碰到这种情况,提示以“root”用户身份运行pip可能会导致权限损坏和冲突,因此我们需要创造一个虚拟的环境区执行它1,1.创建一个虚拟环境python3-mvenvtutorial-env2,在Linux服务器下执行下面命令 sourcetutorial-env/bin/activate这样虚拟环境就搞好了,现在pip安装库不会报错了教程来源
