我有一个使用Spring Boot Actuator的Java后端，但它不会在Digitalocean Ubuntu VPS上启动。 相同的应用程序在我的Mac和其他Ubuntu PC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停在同一点（没有例外，只是挂起）。如果我试图在此时使用^C停止它，它将不会带回来。
这是outoput：

localhost-startStop-1正在尝试创建SecureRandom的新实例，并且它试图从熵源读取数据。这通常是因为源已耗尽。默认熵源为/dev/random。它被称为阻塞源，因为当尝试读取随机数据并且没有可用时，它将阻塞。 Linux上的另一个来源是/dev/urandom。它比/dev/random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争议。 This article可能会引起关注。
总之，使用/dev/urandom可以避免您遇到的问题，但可能会降低安全性。您可以通过系统属性配置Spring Boot的嵌入式Tomcat实例以使用/dev/urandom：
-Djava.security.egd=file:/dev/./urandom
