标签： maven vaadin jetty-9

我想为Vaadin Jetty项目构建并启动可运行的jar。 这是我的pom.xml

我这样创建可运行（独立）的jar：

mvn verify

Maven生成阴影 jar：myproject-1.0-SNAPSHOT-shaded.jar

很好。

我将jar复制到单独的文件夹，然后尝试像这样启动jar：

java  -jar myproject-1.0-SNAPSHOT-shaded.jar

但是我得到了错误：

在我的代码AppStarter中，我尝试启动服务器：

import org.eclipse.jetty.server.Server
import org.eclipse.jetty.server.handler.HandlerList
import org.eclipse.jetty.server.handler.ResourceHandler

      val server = Server(port)
        server.handler = handlers
        server.start() // error here
        server.join()

这可能是没有检测到新的Jetty版本websocket支持并尝试使用特定于旧服务器的实现的气氛。

您可以通过添加init参数来使用JSR356：

<init-param>
   <param-name>org.atmosphere.cpr.asyncSupport</param-name>
   <param-value>org.atmosphere.container.JSR356AsyncSupport</param-value>
</init-param>

或在批注中：

@WebInitParam (
   name = org.atmosphere.cpr.asyncSupport,
   value = org.atmosphere.container.JSR356AsyncSupport
)

这里是同样的问题，为扩展的Web应用程序在../WEB-INF/web.xml下添加了参数，但没有任何内容...
