本文介绍了@ViewScoped @ManagedBean 中的@EJB 导致 java.io.NotSerializableException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经阅读了@ViewScoped 托管 bean 中的 @EJB导致 java.io.NotSerializableException，但我的状态保存设置是 server.
I've read @EJB in @ViewScoped managed bean causes java.io.NotSerializableException, but my state saving setting is server.
这是我所拥有的:

我知道我可以通过将 PersonFacade 声明为 transient 并在重构后使用 JNDI 来获取 EJB 引用来解决这个问题，但我真的不喜欢这种方法.
I know I can workaround this by declaring PersonFacade as transient and use JNDI to get EJB reference after recontruction, but I really dislike this approach.
Glassfish 3.1.1 是否有可能提供不可序列化的 EJB?有没有办法将 @EJB 和 @ViewScoped 一起使用?
Is it possible that Glassfish 3.1.1 provides non-serializable EJBs? Is there a way to use @EJB and @ViewScoped together?
更新:我发现这是一个 MyFaces 相关问题，使用 mojarra 一切正常
update: i found that this is a MyFaces related issue, all is working fine using mojarra
推荐答案
:) 我遇到了同样的问题:https://issues.apache.org/jira/browse/MYFACES-3581
:) I had the same problem: https://issues.apache.org/jira/browse/MYFACES-3581
Apache TomEE 的 David Blevins 帮助我记录了 MyFaces 的错误和补丁.问题是生成的代理类不在其解串器的类加载器路径上.
David Blevins over at the Apache TomEE helped me a log a bug and patch for MyFaces. The problem was generated proxy classes aren't on the classloader path for their deserializer.
解决方法是将此网络应用参数设置为 false:org.apache.myfaces.SERIALIZE_STATE_IN_SESSION
A workaround is to set this web-app param to false: org.apache.myfaces.SERIALIZE_STATE_IN_SESSION
