我正在使用 Spring 3、hibernate 3、derby 10.11 和 apache DBCP2。我正在使用 dao(TestDao) 创建 hibernate session 工厂。这个 DAO 是自动连接的。 当 IOC 试图实例化 dao 时，出现以下异常。
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;
}

最佳答案
DBCP 似乎配置为通过调用 Connection.isValid() 来测试连接的有效性，但是您使用的 JDBC 驱动程序提供的 Connection 实现是基于旧版本尚无此方法的 JDBC API。
我猜想 Derby 一定有一个更新的驱动程序支持这种方法(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，那么我想您也应该能够将 DBCP 配置为不测试连接的有效性，或者以其他方式进行测试。
如果您正在开始一个新项目，那么请不要使用 Spring 3 和 Hibernate 3。它们都非常古老。升级到最新版本，享受过去 5 年所做的所有改进和错误修复。
关于java - spring 3、hibernate、dbcp 和 derby 连接问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32666304/
