错误java.lang.ClassNotFoundException:javax.enterprise.context.spi.context

现在我正在使用以下命令：

• NetBeans 8.2
• ApacheTomcat 8.0.53
• JSF2.2
• 冰面4.3
• 都在Maven项目中（我想是3.6）

我试图用我已经创建的列表填充一个“ace:dataTable”

当我尝试在没有ace:dataTable的情况下运行“Principal.xhtml”时，页面会正常加载，但是如果我添加了ace:dataTable和我想要填充的值，它会显示错误“HTTP 500–内部服务器错误”，例外情况是“javax.servlet.ServletException:javax/enterprise/context/spi/context” javax.faces.webapp.FacesServlet.service（FacesServlet.java:683） org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:52）”

下面是我在pom.xml中使用的依赖项

   <dependency>
            <groupId>org.icefaces</groupId>
            <artifactId>icefaces</artifactId>
            <version>4.3.0</version>
        </dependency>

        <dependency>
            <groupId>org.icefaces</groupId>
            <artifactId>icefaces-ace</artifactId>
            <version>4.3.0</version>
        </dependency>

        <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-web-api</artifactId>
            <version>7.0</version>
            <scope>provided</scope>
        </dependency>

您的pom for cdi api中似乎缺少必需的依赖项：

<dependency>
    <groupId>javax.enterprise</groupId>
    <artifactId>cdi-api</artifactId>
    <version>1.2</version>
</dependency>

javax.enterprise
CDIAPI
1.2

最后，我需要添加CDIAPI依赖项，并且我必须手动将.jar添加到“WEB-INF/lib/”文件夹中

我添加了CDIAPI依赖项，但仍然相同。

import lista.model.PersonaModel;
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import lista.beans.PersonaBean;

@ManagedBean()
@ViewScoped
public class PersonaController {

    private List<PersonaBean> listaPersonaBean;
    private PersonaModel model;

    public PersonaController() {
        consultarLista();
    }

    public void consultarLista() {
        this.listaPersonaBean = this.model.retornaLista();
    }

    public List<PersonaBean> getListaPersona() {
        return listaPersonaBean;
    }

}
