使用 Tomcat 部署 Spring Boot

Question

我想部署我的第一个 Java 应用程序 - 我有地方可以部署它。我用 Tomcat 制作了 Spring Boot 应用程序。使用一些网络指令，我制作了一个胖 jar 文件（maven 包）。我有例外。我尝试搜索它，但任何解决方案都不适用于此。

我可以添加什么 - 我没有设置 Tomcat，简单的基于 Tomcat 的 maven 包 jar。有人能告诉我我能做什么吗？我将非常感谢您的理解和帮助。这是我的第一次部署。

Answer 1

这里有一些要检查的项目......

1 - 确保在 POM 中包含 Tomcat 依赖项。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

2 - 检查您的 application.properties 是否具有正确的端口号。

server.port=XXXX

3 - 如果这是在 linux 环境中运行，请尝试在您的 VM 中运行具有以下内容的应用程序：

-Dserver.port=8181

4 - 确保您的应用程序类扩展 SpringBootServletInitializer：

@SpringBootApplication  
public class App extend SpringBootServletInitializer
{
    public static void main( String[] args )
    {
        SpringApplication.run(App.class, "hello");
    }
}

Answer 2

看来你没有配置有效端口，应该>1024。
