我正在尝试将Neo4J OGM 1.1.1与Play 2 Java框架2.4.2一起使用。但是，当我运行应用程序时，我看到ClassNotFoundException。 以下是我的会议工厂类：

public class Neo4jSessionFactory {
private static SessionFactory sessionFactory = new SessionFactory("org.neo.models");
private static Neo4jSessionFactory factory = new Neo4jSessionFactory();
public static Neo4jSessionFactory getInstance() {
return factory;
}
private Neo4jSessionFactory() {
System.setProperty("username", "neo4j");
System.setProperty("password", "neo");
}
public Session getNeo4jSession() {
return sessionFactory.openSession("http://localhost:7474");
}
}
