我使用的是Spring 3，hibernate 3，derby 10.11和apache DBCP2。我正在使用dao（TestDao）来创建hibernate会话工厂。这个DAO是自动连线的。 当IOC尝试实例化dao时，我得到以下异常。
package com.springtest.dao;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Repository;
import com.springtest.entities.HotelAvailability;
@Repository
public class TestDao {
@Autowired
@Qualifier("sessionFactory")
private SessionFactory sessionFactory;
public List<HotelAvailability> getHotels() {
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
Criteria criteria = session.createCriteria(HotelAvailability.class);
List<HotelAvailability> hotels = (List<HotelAvailability>) criteria.list();
session.getTransaction().commit();
return hotels;
}

答案 0 :(得分：1)
DBCP似乎被配置为通过调用Connection.isValid()来测试连接的有效性，但是您正在使用的JDBC驱动程序提供的Connection的实现是基于旧版本的JDBC API而不是'有这种方法。
我猜Derby必须有一个支持这种方法的新驱动程序（你使用的是旧版本的Spring和Hibernate，所以我猜你也有一个旧版本的驱动程序。）
如果没有，那么我猜你也应该能够配置DBCP不测试连接的有效性，或者用另一种方式测试它。
如果你正在开始一个新项目，那么请不要使用Spring 3和Hibernate 3.它们都很老。升级到最新版本，享受过去5年中所做的所有改进和错误修复。
