Spring Boot应用程序未在独立的Tomcat中加载

Question

我正在尝试在独立的tomcat中运行一个简单的spring boot应用程序。 我尝试遵循参考文档和此处的一些问题/答案，但似乎没有任何效果。 当tomcat启动时，它会部署应用程序，但会完全忽略我的Application类，因此不会加载任何Spring代码。 我敢肯定这一定是我想念的简单东西，但是...？

这是日志文件中的相关输出：

INFO: Deploying web application archive C:\dev\servers\apache-tomcat-7.0.75\webapps\bankweb-0.1.war

INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list o
f JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and
JSP compilation time.

 ms

我已经根据文档更新了Application类，以扩展SpringBootServletInitializer：

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(applicationClass, args);
    }

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

    private static Class<Application> applicationClass = Application.class;
}

@RestController
class GreetingController {

    @RequestMapping("/hello/{name}")
    String hello(@PathVariable String name) {
        return "Hello, " + name + "!";
    }
}

在pom中，我将包装更改为war，并标记了所提供的嵌入式servlet容器：

这已解决，用户错误几乎可以总结出来。 我剥离了所有内容，以删除所有可选的spring模块，使其正常工作，然后一点一点地添加了所有内容，并且一切正常。 我真的不习惯这个春季启动的东西，但是仅仅因为您已经在pom中配置了一个库而包含了功能。 感谢所有花时间阅读的人！
