Spring boot 弹簧靴似乎没有启动

我正在尝试将SpringBootWar部署到DailyRazor托管的私有Tomcat7.0.68实例。我不明白为什么Spring启动应用程序不能工作。我似乎没有犯任何错误。在本地，我已经使用STS3.8.4、Tomcat 7.0.78、Tomcat 8.5.11和其他几个版本的Tomcat实现了这一点

我从来没有在DailyRazor实例上看到Spring Boot横幅显示，也没有看到很多其他日志显示我的Spring Boot应用程序正在启动并加载所有bean。这是我看到的唯一日志记录：

我遵循了打包为WAR、扩展SpringBootServletilizer、重写configure（…）等说明。同样，这些都可以在多个版本的Tomcat上本地工作。我试图调整日志记录，但没有看到任何有用的内容

有什么提示吗？建议

编辑

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

您能确保所有这些操作都正确吗？

从（Spring引导文档）：

创建一个可部署的war文件 生成可部署war文件的第一步是提供

SpringBootServletInitializer

子类并重写其配置 方法。这利用了Spring框架的Servlet3.0支持和 允许您在应用程序由启动时配置应用程序 servlet容器。通常，您会更新应用程序的主类 要扩展SpringBootServletializer：

@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);
    }

}

下一步是更新构建配置，以便 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父级

（配置Maven的 war插件）您只需将

pom.xml

修改为 将包装更改为war：

<packaging>war</packaging>

在我看来一切都很好。@RobertMoskal不，不是。我们应该看到spring引导横幅。我可以确认我正在使用@SpringBootApplication，扩展SpringBootServletializer，并覆盖configure（）。我还可以确认我正在POM中使用spring boot starter父级作为父级，并已将打包设置为WAR。此外，我已经设置了7.0.68和1.7以匹配外部Tomcat实例所使用的内容。我无法独立运行WAR，尽管文档中指出我应该：$java-jar target/plant-service-0.0.1-SNAPSHOT.WAR错误：无法找到或加载主类com.foobar.plant.plantserviceapplicationies，我有提供的弹簧靴启动器tomcat。我能够通过java-jar启动战争。。。在org.springframework.boot中回复后，spring boot maven插件在外部Tomcat中仍然没有成功。如何在Tomcat上部署？我通常只通过本地实例上的“cp”或DailyRazor上的外部实例上的“scp”进行热部署。现在，我正在尝试通过Tomcat管理器来最小化问题。就我所知没有区别。
