SpringBoot应用无法启动嵌入式容器

Question

我有以下错误，我无法运行我的 spring 应用程序。 有谁知道如何解决它？ 我看过类似的帖子，但它没有解决我的问题。 我的课程和 pom 看起来像这样：

 :: Spring Boot ::        (v1.5.8.RELEASE)

应用启动：

@SpringBootApplication
@EntityScan(basePackageClasses = IndexController.class)
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
        System.out.println("The app started properly");
    }
}

我的 pom.xml 很大，所以我只发布那些与 spring 相关的东西。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.8.RELEASE</version>

有不兼容的依赖，这个tomcat版本有一些问题。 此链接有助于了解spring boot 中的问题
