WebSocket <o：socket> NoSuchBeanDefinitionException in Tomcat



我尝试在omnifaces中重新创建演示示例https://showcase.omnifaces.org/push/socket

Tomcat使用以下堆栈跟踪抛出NoSuchBeanDefinitionException

28-Dec-2021 17:29:41.969 SEVERE [http-nio-8080-exec-1] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [default] in context with path [/ms-app] threw exception [Error creating bean with name 'alertUsers': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void com.ms.webapp.action.alertUsers.setPush(org.omnifaces.cdi.PushContext); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.omnifaces.cdi.PushContext] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我在Tomcat中安装了带有balusC教程的Weldhttps://balusc.omnifaces.org/2013/10/how-to-install-cdi-in-tomcat.html

xhtml代码段

<h3>Global counter</h3>
<p>
Below is a static counter which has the same value application wide.
</p>
<h1><h:panelGroup id="count">#{alertUsers.count}</h:panelGroup></h1>
<h:form>
<p>
If you enable the push, then a websocket will be opened.
Note that it's by default always auto-connected when included in the page, but for demo purposes we're initially disabling it.
</p>
<p>
<h:panelGroup id="toggle">
Push is #{alertUsers.connected ? 'connected' : 'disconnected'} 
<h:commandButton value="#{alertUsers.connected ? 'disconnect' : 'connect'} it" action="#{alertUsers.toggle}">
<f:ajax render="toggle increment :count"/>
</h:commandButton>
</h:panelGroup>
</p>
<p>
If push is connected and you press the "increment!" button, then the static counter will increment in bean and the push will send out the new value to the same channel in all connected clients.
To see it yourself, open the same page in multiple tabs/windows/browsers/machines and trigger the push in only one of it.
Note that the counter also won't increment from other side if push is still disconnected on current page.
</p>
<p>
<h:commandButton id="increment" value="increment!" action="#{alertUsers.increment}" disabled="#{not alertUsers.connected}">
<f:ajax />
</h:commandButton>
</p>
</h:form>

<!-- NOTE: having inline script in XHTML like below is bad practice. -->
<!-- It's included directly in XHTML just for sake of demo. -->
<!-- In real world code, put it in a JS file :) -->
<script>
function updateCounter(newvalue) {
$("#count").text(newvalue);
}
function onclosePush(code) {
if (code == -1) {
alert("Oops! Your browser doesn't seem to support web sockets. The push functionality won't work.")
}
else if (code != 1000) {
alert("Oops! Push has stopped working with error code " + code + "! Reload the page.")
}
}
</script>
<!-- End of bad practice ;) -->

<o:socket channel="counter" onmessage="updateCounter" onclose="onclosePush" connected="#{alertUsers.connected}" />

alertUsers.java

import java.io.Serializable;
import java.util.concurrent.atomic.AtomicLong;
import javax.inject.Inject;
import javax.inject.Named;
import org.omnifaces.cdi.Push;
import org.omnifaces.cdi.PushContext;
import org.omnifaces.cdi.ViewScoped;
@Named("alertUsers")
@ViewScoped
public class alertUsers implements Serializable {
private static AtomicLong counter = new AtomicLong();
private boolean connected;
@Inject @Push(channel="counter")
private PushContext push;
public void toggle() {
connected = !connected;
}
public void increment() {
long newvalue = counter.incrementAndGet();
push.send(newvalue);
}
public boolean isConnected() {
return connected;
}
public Long getCount() {
return counter.get();
}
}

Maven spring编译得很好，但当我在WEB/lib中抛出jar时，Tomcatlocalhost会抛出上面的Exception。我目前的猜测是，我不能在omnifaces.cdi.PushContext中使用Inject。我需要专门定义bean吗？怎样

作为一个旁白，如果我使用com.google.inject.inject.而不是javax.inject.inject，Tomcat不会抛出上面的错误，但计数器不会自动更新，并且使用onclosePush函数和1008错误代码关闭了连接。

以防有人需要。我决定放弃Omnifaces Spring，因为它与其他人建议的不兼容。参见此处
