添加气氛后运行项目失败: (AtmosphereFrameworkInitializer.java:52)

Question

我想在 gwt 2.6.1 项目中添加一些 websocket 功能。我已遵循所有指示。不幸的是我收到一个错误：

   [WARN] FAILED AtmosphereServlet: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)Ljavax/servlet/ServletRegistration;
java.lang.NoSuchMethodError: javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)Ljavax/servlet/ServletRegistration;

堆栈跟踪：

使用gwt eclipse插件部署在Jetty服务器上。

Answer 1

看起来你正试图运行在 Jetty 7 上营造气氛。

javax.servlet.ServletContext.getServletRegistration(Ljava/lang/String;)

已添加到 servlet api 的版本 3 中。 Jetty 7 实现了 2.5 版的 servlet api，因此没有实现 getServeletRegistration 方法。哪个应该解释异常。

您可以尝试将 GWT Eclipse 插件更新到 3.0 版。（您可以在 Eclipse 市场找到它，并确保在安装新插件之前卸载旧插件。）

或者您可以尝试使用外部服务器，例如 Tomcat 7 或 8。两者都支持 Servlet 3.0 API。

希望对您有所帮助。
