@ViewScoped托管bean中的@EJB导致java.io.NotSerializableException
我一直在用@ViewScoped托管bean敲打我的脑袋。 我正在使用primeface的“schedule”组件来显示一些事件。 当用户单击特定按钮时，使用ajax调用viewscoped bean中的方法，但每次我得到“java.io.NotSerializableException”时，如果我更改managed-bean范围以请求问题消失。
我究竟做错了什么？ 有任何想法吗？
这是我的托管bean：
@ManagedBean(name = "schedule") @ViewScoped public class ScheduleMBean implements Serializable { @EJB private CongeBean congeBean; @ManagedProperty(value = "#{sessionBean}") private SessionMBean sessionBean; private DefaultScheduleModel visualiseurConges = null; public ScheduleMBean(){ } @PostConstruct public void init() { if(visualiseurConges == null){ visualiseurConges = new DefaultScheduleModel(); } } public void updateSchedule(){ visualiseurConges.addEvent(new DefaultScheduleEvent("test" , new Date(), new Date() )); } public void setVisualiseurConges(DefaultScheduleModel visualiseurConges) { this.visualiseurConges = visualiseurConges; } public DefaultScheduleModel getVisualiseurConges() { return visualiseurConges; } public void setSessionBean(SessionMBean sessionBean) { this.sessionBean = sessionBean; } public SessionMBean getSessionBean() { return sessionBean; } } 这是全栈跟踪

提前致谢
@ViewScoped bean存储在HTTP会话中。 存储在HTTP会话中的任何对象都需要实现Serializable 。 另请参阅在Tomcat部署期间导致java.io.NotSerializableException的JSF托管bean以及java.io.WriteAbortedException：write aborted; java.io.NotSerializableException 。
NotSerializableException通常是自解释的，因为它提到了需要序列化的类的完整限定名，但不能，因为它没有实现Serializable 。
但是，在这种特殊情况下，名称似乎表示自动生成的类，很可能是由EJB容器自动生成的，因此完全不受您的控制。
我以前从未见过这个问题，Google似乎也没有对这个问题给予太多关注。 根据您使用Glassfish v3的堆栈跟踪，我建议发布一个相关的问题 。 同时，最好的办法是将JSF视图状态保存到服务器端。
更新 ：MyFaces中的类似问题表明JSF impl在反序列化期间使用错误的类加载器的特定问题。 升级JSF impl应该可以解决问题： @ViewScoped @ManagedBean中的@EJB导致java.io.NotSerializableException 。
