我认为问题出在Hibernate Helper中，但我不知道在哪里任何建议？

import java.util.Properties;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateHelper {
private static SessionFactory sessionFactory;

    static{
        try {

            Configuration configuration = new Configuration();
            Properties properties = configuration.getProperties();

            ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
                            .applySettings(properties)
                            .buildServiceRegistry();

            sessionFactory = configuration.buildSessionFactory(serviceRegistry);

        } catch (Throwable e) { 
            throw new ExceptionInInitializerError(e);
        }
    }

    public static final SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static final void shutdown(){
        getSessionFactory().close();
    }   
}

使用以下组合时我遇到了同样的问题。

Struts 2.5 jar
Hibernate 4.3.5.Final
MySQL连接器6.0.3
Java 7

在将mysql-connector-java更改为低版本5.1.10时，它已解决。请检查mySQL连接器与Spring和Hibernate jar的兼容性。你也可以看到你的弹簧罐配置。
