问题：

Spring启动执行器应用程序不会在Ubuntu VPS上启动

卫弘懿
2023-03-14

我有一个使用Spring Boot Actuator的Java后端，但它不会在DigitalOcean Ubuntu VPS上启动。同样的应用程序在我的苹果电脑和其他Ubuntu电脑上运行良好。

szabolcs@SmartUpProd:~/smartup$ java -Xmx1536m -jar build/libs/smartup-backend-0.1.0.jar

它开始初始化，但每次都在同一点停止（没有例外，只是挂起）。如果我尝试在此时用^C停止它，它将无法恢复shell。

这是Outoput：

localhost试图创建一个新的SecureRandom实例，但在尝试从熵源读取数据时卡住了。这通常是因为源已经耗尽。默认的熵源是/dev/随机。它被称为阻塞源，因为当试图读取随机数据而没有可用数据时，它会阻塞。Linux的另一个来源是/dev/urandom。它比/dev/随机的主要好处是它是非阻塞的。关于使用/dev/urandom是否会降低安全性，存在一些争论。这篇文章可能会感兴趣。

总之，使用/dev/uradom可以避免您看到的问题，但可能会降低安全性。您可以通过系统属性将Spring Boot的嵌入式Tomcat实例配置为使用/dev/uradom：

-Djava。安全egd=文件：/dev//铀矿
