Question

大约6个月前，我已经在生产中的Linux服务器上部署了独立的jar。它在大约几秒钟内开始。但是，当我在同一台服务器上部署一个新建的jar时。开始大约需要30-45分钟。

由于这个原因，我无法在现有设置上进行任何更改。

我试图在同一台服务器上启动Hello World春季启动应用程序。入门也需要2分钟。

Hello World应用日志：

[support@kbla180303 ~]$ java -jar /app/kpam/kpam-test.jar

我已将Spring Boot版本从1.5.4.RELEASE更新到2.1.4.RELEASE。现在应用程序将在几秒钟内启动。但仍未找到此问题的根本原因。

Spring Boot应用程序需要30-45分钟才能入门
