在ubuntu服务器上运行我的springot web服务Java jar应用程序导致了下面显示的错误，我已经对该错误做了一些研究，但我无法得到解决方案。我用来运行JAR文件的命令是

java -jar mySpringBootApp.jar

尝试以下任一操作：
1)更改/tmp的权限以授予您的用户访问权限。Chmod-R 777/tmp确保您以sudo访问权限(超级用户)运行上述命令
2)将属于的用户添加到sudo组。

对于在运行/调试配置中提供环境变量时从IntelliJ IDEA运行时获得相同异常的用户：请查看是否选中了“Include Parent Environment Variables”(包括父环境变量

如果您在Kubernetes中部署Spring Boot应用程序时遇到此问题，值得检查的配置之一是readOnlyRootFilessystem。在您试图故意运行只读容器之前，必须将其设置为FALSE。
它可以在部署配置中使用，如下所示：

template:
    metadata:
      labels:
        app: hello
    spec:
      containers:
      - name: hello
        image: hello-world
        securityContext:
          runAsUser: 1000
          readOnlyRootFilesystem: false ## this should not be true

您的应用程序用户可能没有足够的权限在/tmp目录中创建任何内容...请参阅最后一条消息Caused by: java.io.IOException: Read-only file system

最有可能的解释是根文件系统已满。这对我来说是个问题。

出现此错误的原因之一是您没有包括系统环境变量。可能您尝试使用在Java IDE中定义的不同系统变量来定义新配置，但您禁用了默认环境变量。
