dpHibernate：serializerFactory沒有被Spring初始化 - > NullPointerException在服務訪問

我想在Apache Tomcat 7.0.12上使用BlazeDS 4.0.0.14931，Spring 3.0.5和Spring-BlazeDS-Integration 1.5運行dpHibernate 2.0 RC6。 0.M2dpHibernate：serializerFactory沒有被Spring初始化 - > NullPointerException在服務訪問

通過以下配置，服務器可以正常啓動，但只要我想通過FlashBuilder4 DCD訪問服務或RDSDispatchServlet，就會收到NullPointerException異常。看來serializerFactory沒有正確注入到dpHibernate HibernateUtil中。我在remoting-config.xml中的配置中錯過了什麼嗎？

凹凸，任何？ – Rob 2011-04-12 08:31:24

是不需要的remotingConfig.xml，並且似乎是什麼導致你的問題。

通常，在Spring配置，還有你的HibernateUtil班上有沒有使用（該SpringContextSerializerFactory返回的SessionFactory，以確保您得到您的春季會議正確的）

然而，看起來像你的remotingConfig.xml文件覆蓋默認設置，迫使它使用舊的HibernateUtil方法，這是扔你的NPE。
