Question

这有效：

Facelet代码段：

<p:socket channel="/redirectMonitoring">
    <p:ajax event="message" oncomplete="window.location.replace('/foo.xhtml')" />
</p:socket>

资源：

@PushEndpoint("/redirectMonitoring")
@Singleton
public class RedirectMonitorResource {
    @OnMessage() public void onMessage(Boolean ignore) {}
}

CDI bean：

@Model
public class RedirectBean {
    public void redirect() {
        EventBus eventBus = EventBusFactory.getDefault().eventBus();
        eventBus.publish("/redirectMonitoring", Boolean.TRUE);
    }
}

但是当我尝试使路径动态如下：

的facelet：

<p:socket onMessage="handleMessage" channel="/redirectMonitoring/{sessionId}" autoConnect="false" widgetVar='subscriber'/>
<script type="text/javascript">
    function handleMessage(message) {
        window.location.replace(message);
    }
</script>

通过会话ID连接的Bean：

@Model
public class LoginController {
    private void onLogin(@Observes @LoggedIn User loggedInUser) {
        RequestContext.getCurrentInstance().execute(
            "PF('subscriber').connect('/redirectMonitoring/" + WebUtil.getSession().getId() + "')");
    }
}

资源：

@PushEndpoint("/redirectMonitoring/{sessionId}")
@Singleton
public class RedirectMonitorResource {
    @PathParam("sessionId") private String sessionId;

    @OnMessage(encoders = {JSONEncoder.class}) public String onMessage(String message) { return message; }
}

CDI bean：

@Model
public class RedirectBean {
    public void redirect(String sessionId) {
        EventBus eventBus = EventBusFactory.getDefault().eventBus();
        eventBus.publish("/redirectMonitoring/" + sessionId, "/foo.xhtml");
    }
}

网页浏览器没有加载/foo.xhtml，我在日志中收到以下错误：

P.S。我确实设置了断点以确保会话ID在

中

"PF('subscriber').connect('/redirectMonitoring/" + WebUtil.getSession().getId() + "')"

匹配

中的会话ID

eventBus.publish("/redirectMonitoring/" + sessionId, "/foo.xhtml");

非常感谢任何建议/指示/建议！

更新：

我正在使用PrimeFaces 5.2 + Atmosphere 2.3.4。

我确实将p:socket更改为autoConnect="true"，但这样做并没有帮助。

以下是我在浏览器针对Web应用程序发出请求时通过浏览器控制台/网络选项卡看到的内容：

https://localhost:8443/app/primepush/redirectMonitoring/%7BsessionId%7D?X-Atmosphere-Transport=close&X-Atmosphere-tracking-id=5f40ca65-0ab0-4c4c-ab58-7b9b790eb78f&_=1440535767013

但是，当Web应用程序尝试通过/redirectMonitoring端点向Web浏览器发送消息时，我在控制台/网络选项卡上看不到任何活动。

这是另一条线索：

当我在静态路径版本的RedirectMonitorResource＃onMessage中设置断点时，会在调试会话中触发断点：

@PushEndpoint("/redirectMonitoring")
@Singleton
public class RedirectMonitorResource {
    @OnMessage() 
    public void onMessage(Boolean ignore) {} // <-- breakpoint here is triggered
}

但是，当我在动态路径版本中设置断点时，断点不被触发。 RedirectMonitorResource＃onMessage不会在动态路径版本中调用：

@PushEndpoint("/redirectMonitoring/{sessionId}")
@Singleton
public class RedirectMonitorResource {
    @PathParam("sessionId") private String sessionId;

    @OnMessage(encoders = {JSONEncoder.class}) 
    public String onMessage(String message) { 
        return message;                          // <-- breakpoint here not triggered 
    } 
}

Answer 1

解决方案是改变p：socket channel属性：

<p:socket channel="/redirectMonitoring/{sessionId}" ... />

到此：

<p:socket channel="/redirectMonitoring/#{session.id}" ... />

Primefaces Push无法获得动态路径
