java - JAR 文件可以在 Windows 上运行，但不能在 Linux 上运行

Question

我已经在 Maven 上创建了一个 JAR 文件。该应用程序包含 Spring Boot 和 Vaadin。我可以在 Windows 上运行它。当我尝试在 Linux 上运行时，它说 Tomcat 无法启动。

我想知道这是否是 OpenJDK 的问题，因为这是我现在看到的唯一区别。在 Windows 上，我使用 Oracle JDK 8。

我尝试在 AWS、Docker、Ubuntu 上运行。相同的结果。Windows 10 - 好的。

Answer 1

我找到了问题/解决方案:

1) 将 debug=true 添加到 application.properties

2)运行后我发现了它:

Caused by: java.lang.IllegalStateException: Running project in development mode with no access to folder...

改为在生产模式下构建项目，请参阅 https://vaadin.com/docs/v14/flow/production/tutorial-production-mode-basic.html

3) 在 Vaadin GitHub 上，有一种在生产环境中创建 JAR 文件的方法:

mvn clean package -Pproduction

问题解决了，应用程序正在运行。
