我在我的Ubuntu 22.04机器上安装了Tomcat 8.5。我能够在localhost：8080上使用startup.sh文件和systemctl服务测试tomcat。但是，当我在tomcat上部署应用程序的war文件时，我无法连接到localhost：8080。systemctl status tomcat显示为active。
当我使用startup.sh手动启动我的tomcat时，我可以连接到localhost：8080和localhost：8080/myapp。
在比较了两种情况下的 Catalina .out日志后，我发现在手动启动tomcat时，我的日志文件会得到以下日志：
正在配置Spring Security Core..已完成配置Spring Security Core
我可以使用tomcat连接到我的应用程序。但是，每当我使用systemctl启动tomcat时，tomcat就开始运行了，但我永远无法访问它。在这种情况下，我的日志文件没有Spring Security Core行。
下面是我的systemctl文件：

[Unit]

ExecStop=/opt/tomcat/bin/shutdown.sh

#RestartSec=10
#Restart=always

[Install]

没有与tomcat用户权限和所有权相关的问题，因为我可以使用以下命令启动并连接到我的应用程序：

sudo -u tomcat bash -c '/opt/tomcat/bin/startup.sh'

编辑：
journalctl输出：
