An AnnotationConfiguration instance is required to use...等几个异常

1.异常： An AnnotationConfiguration instance is required to use
意思是，用了注解了，自然要用注解类生成SessionFactory

 private static Configuration configuration = new AnnotationConfiguration();

当然了，如果你用Hibernate4以上的版本，就没有这种问题了。

 private static org.hibernate.SessionFactory sessionFactory;    private static Configuration configuration = new Configuration();    private static ServiceRegistry serviceRegistry; serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();            sessionFactory = configuration.buildSessionFactory(serviceRegistry);

特别要注意：注解时Mapper后面是class。不是resource。
2.异常：
java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory，很明显，缺少二级缓存要用的commons.logging jar包
3.在Properties中，冒号要转义：如

jdbc.url=jdbc\:mysql\://localhost\:3306/test
