作为Maven的新手,我正在尝试用嵌入式码头制作一个可执行jar的webapp 。不幸的是,我在实现这一目标方面遇到了很多困难,并决定按照一步一步的进展:首先使用jetty-maven-plugin(好的,有很多痛苦),然后使用jetty-runner(KO,这个问题)这个SO问题),最后使用嵌入式码头(KO)。
我花了这么多时间做这件事,根据码头版本有不同的例外情况并抽出那么多头发,我终于决定向社区寻求帮助。
我希望这个问题不会被标记为SO #12241989(或任何其他类似的)的副本,因为我有同样的问题,但显然不是因为我使用了相同版本的jetty-maven-plugin和jetty-runner。
webapp使用JSF2(mojarra 2.2.8)+ CDI(焊接)+ Primefaces + Websockets

使用此配置,应用程序可以正常运行。 松了一口气
我相信使用jetty runner重现上述配置的最简单方法是使用描述我的webapp的jetty context xml文件。所以我最终得到了以下上下文文件:
context.xml中
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
<Set name="contextPath">/</Set>
<Set name="war">target/myapp.war</Set>
<Set name="descriptor">src/main/webapp/WEB-INF/web.xml</Set>
<Set name="overrideDescriptor">src/main/webapp/WEB-INF/jetty-web-override.xml</Set>
<Set name="serverClasses">
<Array type="java.lang.String">
<Item>

</Item>
</Array>
</Set>
<New id="appManager" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>BeanManager</Arg>
<Arg>
<New class="javax.naming.Reference">
<Arg>javax.enterprise.inject.spi.BeanManager</Arg>
<Arg>org.jboss.weld.resources.ManagerObjectFactory</Arg>
<Arg />
</New>
</Arg>
</New>
</Configure>
然后当我运行jetty runner(版本相同)时:
java -jar jetty-runner-9.0.4.v20130625.jar context.xml
......一切似乎都没问题,除了(烦人的)我的应用程序的启动监听器(用Servlet 3.0 @WebListener
注释)无法启动。
如果我尝试导航到http://localhost:8080/
,我会得到以下堆栈跟踪:

如果我尝试通过在web.xml中指定来强制监听我的StartupListener类:
<listener>
<listener-class>fr.mygroup.myapp.listeners.StartupListener</listener-class>
</listener>
......我得到同样的错误。
无论如何,我的StartupListener没有被监听的事实显然不是错误的原因,而是结果。但我无法弄清楚我的码头配置有什么问题。
我绝望地觉得去我的webapp的可执行文件überjar还有很长的路要走:(
