spring - 在 Tomcat 服务器上部署 Spring boot war 文件时出错

Question

我有一个 Spring boot 应用程序，我正试图将它部署到 Tomcat 服务器上。当我在 eclipse 中本地运行应用程序时，它已成功部署。但是当我尝试在 Linux tomcat 服务器上部署时。它失败。我不确定配置有什么问题。我试图将 war 文件放在 tomcat webapps 文件夹下并运行 startup.bat 文件。但它继续运行日志跟踪。请建议我应该尝试什么。

Answer 1

能够在您已经完成的工作之上创建可部署的 war 文件；

1) 您的主要(应用程序类)应该扩展 SpringBootServletInitializer 并重写配置方法，如下所示:

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

2) 在您的 pom 文件中，您应该向 tomcat 添加提供的依赖项，以防止嵌入式容器干扰外部容器:

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

添加这些后，它应该可以正常工作。
