これはstackoverflowに関する私の最初の投稿です
jsf2のApplicationScopeBeanにEntityManagerFactoryを作成したいのですが、これが私のBeanです。
@ApplicationScoped
@ManagedBean(eager = true)
public class ApplicationContext implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private EntityManagerFactory entityManagerFactory = null;
private EntityManager entityManager = null;
public ApplicationContext(){
}
public EntityManagerFactory getEntityManagerFactory() {
return entityManagerFactory;
}
public void setEntityManagerFactory(EntityManagerFactory entityManagerFactory) {
this.entityManagerFactory = entityManagerFactory;
}
public EntityManager getEntityManager() {
return entityManager;
}
public void setEntityManager(EntityManager entityManager) {
this.entityManager = entityManager;
}
@PostConstruct
public void applicationInitialized(){
System.out.println("application is being initialized");
this.entityManagerFactory = Persistence.createEntityManagerFactory("PersonalProject");
this.entityManager = this.entityManagerFactory.createEntityManager();
}
@PreDestroy
public void applicationDestroyed(){
System.out.println("application being destroyed");
}
}
これには、巨大な例外スタックトレースがあります。

根本的な原因は、Postクラスがシリアライズ可能を実装していないためだと言っています。しかし、それはすでに次のように実装されています。
public class Post implements Serializable {}
この問題は、ApplicationScopedManagedBeanでのみ発生します。ServletContextListenerを使用してEntityManagerFactoryを作成しようとすると、問題なく作成されます。
何が問題になる可能性がありますか？ApplicationScoped Beanに関する知識が不足していますか？
