我有一个使用 vaadin 和 vaadin-cdi 组件的 Java EE 7 应用程序。
没有 vaadin push 这是我的配置:
// the Servlet
@WebServlet(value = "/*", asyncSupported = true)
public class MyServlet extends VaadinCDIServlet {
@Override
protected void servletInitialized() throws ServletException {
super.servletInitialized();
}
}
// ... Then I have a @CDIUI anotated class.
在这里一切正常，直到我将 @Push 添加到我的 @CDIUI 带注释的类并在类路径中添加 vaadin-push 组件
<dependency org="com.vaadin" name="vaadin-push" rev="&vaadin.version;" />
然后我在wildfly尝试访问我的应用程序时遇到此错误

我什至添加了一个像这样的 web.xml 文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<listener>
<listener-class>org.atmosphere.cpr.SessionSupport</listener-class>
</listener>
<context-param>
<param-name>org.atmosphere.cpr.SessionSupport</param-name>
<param-value>true</param-value>
</context-param>
</web-app>
但错误仍然相同。我真的不明白。我究竟做错了什么 ？
我使用的是最新的 vaadin 7.4.1、vaadin-cdi 1.0.1 和 wildfly 8.2
最佳答案
Vaadin 引入了一种新模式， WEBSOCKET_XHR (从服务器到客户端的 WebSockets，从客户端到服务器的 XHR)它允许设置 cookie，使用带有 CDI/Spring 的请求范围等。
见 https://vaadin.com/download/release/7.6/7.6.0/release-notes.html
由 回答 Marcus Hellberg 并从 this thread of vaadin forum 中提取。 (我发现把它放在这里很重要，因为我在论坛上先在 StackOverflow 中完成了。)
关于java - Vaadin + CDI + Push(气氛)不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/28967099/
