spring - 瓦丁。同时运行 2 个 spring 应用程序

Question

我有一个多模块 spring gradle 应用程序。2 个模块是可执行的，两个模块都使用 vaadin 14.1.17。我使用远程服务器同时部署两个 jar，但是每次运行第二个应用程序时，第一个都会中断。帮助了解问题所在。堆栈跟踪损坏的应用程序：

每个应用程序都在单独的端口上运行。此外，在通过网络浏览器第一次调用之前，第一个应用程序不会中断。我在 Linux 服务器上启动应用程序作为 systemd 服务。我再重复一遍。在我通过浏览器访问之前，这两个服务都在运行并且不包含错误。但是在我访问第一个正在运行的应用程序后，它崩溃了，但第二个继续工作
