我正在尝试让 dpHibernate 2.0 RC6 在带有 BlazeDS 4.0.0.14931、Spring 3.0.5 和 Spring-BlazeDS-Integration 1.5.0.M2 的 Apache Tomcat 7.0.12 上运行
使用以下配置，服务器可以正常启动，但只要我想通过 FlashBuilder4 DCD 访问服务或 RDSDispatchServlet，我就会收到 NullPointerException。似乎 serializerFactory 未正确注入 dpHibernate HibernateUtil。我是否错过了 remoting-config.xml 中的配置中的某些内容？
