Spring Boot 应用程序无法启动。错误：停止服务 [Tomcat]。

我无法使用嵌入式Tomcat运行我的Spring Boot应用程序。它之前一直可以正常运行，我没有对配置进行任何更改。当我在eclipse中将应用程序以Spring Boot App方式运行时，tomcat在启动过程中立即停止。

我尝试了重启机器、eclipse、刷新项目、重新创建.m2存储库，但都没有帮助我解决问题。

以下是我的配置信息：

Main Class

@SpringBootApplication
@PropertySource(value="classpath:messages.properties")
public class ExampleApplication {
    public static void main(String[] args) {
        SpringApplication.run(ExampleApplication.class,       args);
    }
}
