我尝试使用gui管理器将我的war文件部署在远程ubuntu tomcat 8.5服务器上。但是部署失败并返回这个错误：

启动组件失败[标准引擎[Catalina].标准主机[localhost].标准上下文[/rest-api-0.0.1-SNAPSHOT]]

这是我的pom. xml：

这是我java课的起点：Application.java

package com.faceRecon.restapi;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import  org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer{

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

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

}
