问题：
Java Springboot“无法启动ServletWebServerApplicationContext”错误
湛财
我知道有好几篇关于这件事的帖子，但没有任何具体的帮助。我有一个Java Springboot rest API，它在localhost上运行良好，但在尝试作为jar运行时会抛出一个错误。
这是我的主要课程：
@SpringBootApplication
public class HarrierApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(HarrierApplication.class, args);
}
这是我尝试运行jar文件时的输出：
21:03:35.089 [main] DEBUG o.s.u.c.s.UiApplicationContextUtils - Unable to locate ThemeSource with name 'themeSource': using default [org.springframework.ui.context.support.ResourceBundleThemeSource@3e681bc]

我的pom。xml是我所有修复这一问题的尝试中的一个烂摊子，但它是：

我试过使用java 8和java 11中的所有依赖项，但没有发现任何问题。您是否在属性文件中添加了任何其他属性，如下所示。
Spring.main.web-application-type= none
如果是这样，请将其移除。
我向你们展示了tomcat的依赖性，移除了一个成为spring核心的tomcat本身。
如果您有任何额外的配置，请ping也。
