老師，我寫了一個(gè)簡單示例程序，打包成war,部署在jetty（jetty 9.x）容器下一直不能啟動項(xiàng)目，不知道什么原因，也沒有錯(cuò)誤日志打印，訪問的時(shí)候返回404，但是部署在Tomcat容器或者使用java -jar 命令是可以成功啟動的，其中spring boot啟動類代碼如下：

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

@SpringBootApplication
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);
???}
}

pom.xml 文件主要配置如下：

我重寫了代碼，問題均能重現(xiàn)，初步懷疑是jetty容器的原因，希望能得到老師的解答，
