java - Vaadin + CDI + 推送(大气)不起作用

Question

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.

在我将@Push 添加到我的@CDIUI 注释类并在类路径中添加 vaadin-push 组件之前，这里一切正常

<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 web.xml 文件，如下所示:

<?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>

但是错误还是一样。我真的不明白。我做错了什么？

我正在使用最新的 vaadin 7.4.1、vaadin-cdi 1.0.1 和 wildfly 8.2

Answer 1

Vaadin 引入了一种新模式，WEBSOCKET_XHR(WebSockets 从服务器到客户端，XHR 从客户端到服务器) 允许设置 cookie，使用 CDI/Spring 等的请求范围

参见 https://vaadin.com/download/release/7.6/7.6.0/release-notes.html
