Question

每当我尝试在localhost：8080上运行java镜像快速启动主机时，我就会得到。

            HTTP ERROR: 503
            Problem accessing /. Reason:
            SERVICE_UNAVAILABLE
            Powered by Jetty://

我正在使用mav jetty：在命令行中运行。我不知道我哪里出错了。我担心解决方案正在打击我，我无法看到它。

任何帮助将不胜感激，提前谢谢。

看起来Web应用程序无法找到声明的servlet SignOutServlet。

此servlet已被删除a few commits back，看起来您的web.xml文件与可用来源不同步。您有几种方法可以解决此问题：

制作新的克隆/下载最新版Java quick start的zip文件（这可能是最简单的解决方案）

从src/main/webapp/WEB-INF/web.xml中删除对{8}的所有对SignOutServlet的引用。

  <url-pattern>/attachmentproxy</url-pattern>
</servlet-mapping>

<!-- remove stuff below here -->
<servlet>
  <servlet-name>signout</servlet-name>
  <servlet-class>com.google.glassware.SignOutServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>signout</servlet-name>
  <url-pattern>/signout</url-pattern>
</servlet-mapping>
<!-- remove stuff above here -->


<welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

一旦删除了这些依赖项，请在构建好的度量之前进行清理：

$ mvn clean jetty:run
