Vaadin 7，Atmosphere 和服务器推送问题

Question

我已经开始使用 Vaadin 7.2.4 的 Maven 原型构建一个项目，并且遇到了很多与 Atmosphere 启动问题相关的错误。就目前情况而言，我将无法启用使用插件 (OAuthButtonPopup) 所需的推送支持。尽管有很多关于 Atmosphere 的一般性聊天，但我似乎找不到任何特定于这个问题的内容，所以我想知道我这边是否存在安装/配置问题，特别是因为似乎有人试图实例化与 Jetty 相关的一些类这似乎与我的安装无关。

当前设置如下： Java 8 SDK、Java EE7 JDK、Idea IntelliJ 13、Vaadin 7.2.4 和 Wildfly 8。

任何指针将不胜感激。

部署错误跟踪如下：

Answer 1

根据 rustproofFish 和 Raffael 之前的回答，我能够通过添加这些排除项来修复错误：

   <groupId>com.vaadin</groupId>
   <artifactId>vaadin-client-compiler</artifactId>
   <version>${vaadin.version}</version>
   <exclusions>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-servlets</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-annotations</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-util</artifactId>
        </exclusion>
    </exclusions>

Answer 2

感谢 Raffael 的指点 - 你说得很对。由于将 Vaadin 7.2.4 原型中的一个依赖项从 vaadin-client-compiled 更改为 vaadin-client-compiler 以使项目在首次运行时构建和编译，因此构建中包含了 Jetty 依赖项（请参阅 Vaadin 论坛上题为 GWT 编译器错误 - Vaadin Charts using Maven and IntelliJ https://vaadin.com/forum#!/thread/4751650) 的帖子。依赖树的错误错误如下：

将 pom.xml 条目改回 vaadin-client-compiled，清理和重建解决了不正确的依赖关系； Atmosphere 现在开始时没有错误/警告，并且根据我迄今为止的有限测试，推送功能似乎存在且正确。

Answer 3

对我来说，您的 war 包中似乎包含不应打包的库。您可能会查看您的战争以查看包含哪些 jar 依赖项。也许码头的某些部分。 你可以使用

mvn dependency:tree

查看它们的来源并在必要时排除它们。

要启用推送，此 wiki 页面描述了所有必需的步骤：https://vaadin.com/wiki/-/wiki/Main/Enabling%20server%20push

Answer 4

我在使用 Tomcat 时遇到了类似的错误。我通过在我的 web.xml 上添加以下内容来修复错误

    <init-param>
        <param-name>org.atmosphere.cpr.asyncSupport</param-name>
        <param-value>org.atmosphere.container.Tomcat7AsyncSupportWithWebSocket</param-value>
    </init-param>
