Tomcat中的WebSocket<o：socket>NoSuchBeanDefinitionException-编程知识-白鹭情

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

Tomcat 使用以下堆栈跟踪抛出 NoSuchBeanDefinitionException

<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. -->

        }
        else if (code != 1000) {
            alert("Oops! Push has stopped working with error code "   code   "! Reload the page.")
        }
    }
</script>
