java - 在 Jenkins 上部署 Spring Boot 应用程序

Question

我正在 Jenkins 端口 8081 上部署 Spring Boot 应用程序。我在端口 5050 上运行了 tomcat。当我部署应用程序时，它会显示一条成功消息，但是当我导航到 localhost:5050/{given context name} 时，它会向我显示 404 Not found信息。我也尝试过使用嵌入式方式它不起作用如果有任何方法可以更好地使用嵌入式 tomcat 进行部署

Jenkins 是一个 CI/CD 软件，用于构建您的应用程序(而不是将其部署在 Jenkins 服务器上)。你在哪里运行它是一个不同的主题。
Jenkins 在构建您的 Java 可执行文件 (.war) 时所做的一切都是正确的。您现在应该做的是在服务器上运行这个构建的可执行文件。
考虑使用 Docker 在 Jenkins 中构建您的应用程序，并在不同的服务器上启动生成的 Docker 容器。
