Spring Boot似乎无法启动

我正在尝试将Spring Boot WAR部署到DailyRazor托管的私有Tomcat 7.0.68实例。我无法弄清楚为什么Spring Boot应用程序不起作用。我似乎没有任何错误。在本地，我已经使用了STS 3.8.4，Tomcat 7.0.78，Tomcat 8.5.11以及其他几个版本的Tomcat。

我从未在DailyRazor实例上看到Spring Boot横幅显示，也没有看到我的Spring Boot应用程序正在启动并加载所有bean的其他日志记录。这是我看到的唯一记录：

我遵循了包装作为WAR的说明，扩展了SpringBootServletInitializer，覆盖了configure（...）等。再一次，这一切都在Tomcat的多个版本上本地工作。我试图调整日志记录，但我没有看到任何有用的东西。

任何提示？建议？

修改

不确定它是否相关，但在关闭Tomcat时，我看到以下内容：

INFO main org.apache.catalina.core.StandardService - Stopping service Catalina

您能否确保完成所有这些操作？

来自 Create a deployable war file （Spring启动文档）：

  

创建可部署的war文件

     

生成可部署的war文件的第一步是提供一个   SpringBootServletInitializer子类并覆盖其配置   方法。这利用了Spring Framework的Servlet 3.0支持和   允许您在应用程序启动时configure应用程序   servlet容器。通常，您更新应用程序的主类   扩展SpringBootServletInitializer：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}
     

下一步是更新您的构建配置，以便您的   project生成war文件而不是jar文件。如果你正在使用   Maven并使用spring-boot-starter-parent（配置Maven的   你的战争插件）你需要做的就是修改pom.xml   将包装改为战争：

<packaging>war</packaging>

修改

您是否有spring-boot-starter-web和spring-boot-starter-tomcat个依赖关系？

  

构建一个可执行且可部署到的战争文件   您需要标记嵌入式容器的外部容器   依赖性为“提供”，例如：
