问题
I am using Spring 3, hibernate 3, derby 10.11 and apache DBCP2. I am using a dao(TestDao) to create the hibernate session factory. This DAO is auto-wired. I am getting the following exception when IOC is trying to instantiate the dao.
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;
}

回答1:
DBCP seems to be configured to test the validity of the connections by calling Connection.isValid(), but the implementation of Connection provided by the JDBC driver you're using is based on an older version of the JDBC API which didn't have this method yet.
I guess that Derby must have a newer driver that supports this method (you're using old versions of Spring and Hibernate, so I guess you also have an old version of the driver).
If it doesn't, then I guess you should also be able to configure DBCP not to test the validity of connections, or to test it in another way.
If you're starting a new project, then please don't use Spring 3 and Hibernate 3. They're both very old. Upgrade to their latest version, and enjoy all the improvements and bug fixes that have been made in the last 5 years.
