服务器端Omnifaces推送。 PushContext为null

Question

我的问题是关于服务器端 Omnifaces Push。因此，我试图在项目上集成Omnifaces Push，但是当我尝试发送消息时，PushContext实例出现了问题（PushContext实例为null）。

技术堆栈

• Tomcat 9.0.22
• 3.2.1级
• JSF 2.2
• Primefaces 6.2
• Omnifaces 2.7.1
• cdi api 2.0
• 焊接servlet阴影3.0.5.Final

我有一个CDI容器，我想注入一些PushContext实例（不同的推送通道），但是这些实例没有被注入或被错误地注入为null。当我调用 notificar 方法时， pushInicio 为空。

配置

web.xml

@Named
@Startup
public class ControladorMedidas
        implements Serializable {
    @Inject
    @Push(channel = "inicio")
    private PushContext pushInicio;

    @Inject
    @Push(channel = "centro")
    private PushContext pushCentro;

    ...
    private void notificar() {
        // pushInicio -> null
        pushInicio.send("some message");
    }
}

context.xml

<?xml version="1.0" encoding="UTF-8"?>

似乎OmniFaces已正确加载，因为Tomcat跟踪以下行：

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/servicios">
    <Resource
            name="BeanManager"
            auth="Container"
            type="javax.enterprise.inject.spi.BeanManager"
            factory="org.jboss.weld.resources.ManagerObjectFactory"
    />
</Context>

另一方面，Tomcat不会引发任何与Omnifaces相关的错误。

谢谢。
