给定在GlassFish服务器4.0上运行的JSF 2.2.6中的以下CDI bean
import javax.inject.Named;
import javax.faces.view.ViewScoped;
import java.io.Serializable;
import org.primefaces.model.LazyDataModel;
@ViewScoped
@Named("myBean")
public class MyBean extends LazyDataModel<T> implements Serializable
{
@Inject //Injecting an EJB.
private MyLocalEJB service;
private static final long serialVersionUID = 1L;
}
这会导致在取消应用程序部署时抛出以下异常。

在JSF 2.2中，CDI bean有一个ViewScoped。为什么会抛出这个异常呢?
也是Java EE 7通过IDE (NetBeans 8.0)发出警告，
未满足的依赖:没有bean匹配注入点
在bean中执行以下语句:
private MyLocalEJB service;
在Java EE 7中，不需要创建beans.xml文件。因此，不应发出此警告。有必要在Java EE 7中创建beans.xml吗?
. io .NotSerializableException: org.jboss.weld.bean.ManagedBean
这是Mojarra中的一个bug。它被报道为第3191期。这个问题在Mojarra 2.2.7中得到了修复，预计将于2014年7月3日发布。如果您需要立即修复它，请抓取2.2.7快照。下载详情请参阅如何下载Mojarra JSF夜间构建的答案。

对不起，我不懂Netbeans。如果你已经在使用最新的Netbeans版本，并且你确信Netbeans是错误的(即除了特定的异常之外，一切都只是工作)，那么你会向他们报告一个问题。
在Java EE 7中，不需要创建beans.xml文件。因此，不应发出此警告。
你完全正确。参见Reza Rahman的博客:Java EE 7中的默认CDI启用
