我有一个JavaFX应用程序，它工作正常，直到我添加一个2º缓存（ehcache与区域）。在那之后，我开始申请，但我得到这个错误时尝试创建会话工厂：休眠+ c3p0池+ ehcache失败开始
08/10/2014 20:01:40 DEBUG Configuration:1841 - Preparing to build session factory with filters : {}

的HibernateUtil
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public enum Util {
INSTANCE;
private final SessionFactory sessionFactory;
private Util() {
Configuration configuration;
StandardServiceRegistryBuilder builder;
configuration = new Configuration().configure();
builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
sessionFactory = configuration.buildSessionFactory(builder.build());
}
public static Util getInstance() {
return INSTANCE;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
}
当我尝试调试，停在sessionFactory = configuration.buildSessionFactory(builder.build());因为会话回报为空。但如果我删除池，会话的作品。
此外，在所有* .hbm.xml文件中，我通过放置<cache usage="nonstrict-read-write" region="region1"/>来设置缓存。如果我删除区域，启动但我得到一个错误，因为我没有定义一个区域，休眠采用默认名称。
