How to update JSF 2.2 to JSF 2.3 using Maven in a Spring Application

https://blog.payara.fish/jsf-2.3-the-websocket-quickstart-under-payara-server

maven依赖项是：

    <dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <version>2.0</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.weld.servlet</groupId>
        <artifactId>weld-servlet-shaded</artifactId>
        <version>3.0.3.Final</version>
    </dependency>

    <dependency>
        <groupId>org.primefaces</groupId>
        <artifactId>primefaces</artifactId>
        <version>6.2</version>
    </dependency>

这是test.xhtml：
