如何更改springboot應用程序啟動目錄？

Question

我在 CENTOS7 上運行一個 springboot 應用程序作為服務。 默認啟動目錄是“/”，現在我想更改為配置文件所在的“/home/centos/fpcyproxy”。
如何改變它？

Answer 1

如果您正在談論應用程序的 homedir - 嘗試設置 WorkingDirectory 屬性：

[Service]
WorkingDirectory=/home/centos/fpcyproxy

但是，如果您正在談論加載位於外部目錄中的application.properties ，請嘗試設置下一個屬性

ExactStart=/usr/bin/java -jar /home/centos/fpcyproxy/fpcyproxy-1.0.0.jar --spring.config.location=/home/centos/fpcyproxy/
