尝试将hibernate版本3.6 ..更新为4.3。*

时出现以下错误

我的Hibernate Util类是

private static SessionFactory buildSessionFactory() {
        try {
            SessionFactory sf = null;
            Configuration configuration = new Configuration().configure();
            //From the properties file
            serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                    configuration.getProperties()).build();
            if (StringUtils.isNotBlank(Config.getHibernateConfigFile())) {
                ClassLoader loader = HibernateUtil.class.getClassLoader();
                if (loader == null)
                    loader = ClassLoader.getSystemClassLoader();

                java.net.URL configURL = loader.getResource(Config.getHibernateConfigFile());
                if (null != configURL) {
                    log.info("Configuring hibernate using " + Config.getHibernateConfigFile() + " located at " + configURL.toString());
//                 sf = new Configuration().configure(configURL).buildSessionFactory();
                    configuration = configuration.configure(configURL);
                    serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
                    sf = configuration.buildSessionFactory(serviceRegistry);

                } else
                    log.warn("Config file not found " + Config.getHibernateConfigFile());
            }
            //Default hibernate.cfg.xml from resource
            if (null == sf) {
                sf = configuration.buildSessionFactory(serviceRegistry);
            }
            return sf;
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            ex.printStackTrace();
            throw new ExceptionInInitializerError(ex);
        }
    }

我尝试了很多方法来解决它无法找到它，有人可以帮助我吗:)。

Answer 1

Bonecp ConnectionProvider的问题，Hibernate 4.3.9需要来自包源的连接提供程序，该包被移动到bonecp-0.8.0.alpha中的另一个包，这会导致问题

删除了bonecp并使用了hibernate 4.3。*默认支持的hikaricp

**注意：来自hikari的是hibernate 4.3 *的默认支持者

初始SessionFactory创建失败.java.lang.NoClassDefFoundError：org / hibernate / service / jdbc / connections / spi / ConnectionProvider
