在测试hibernate是,当程序运行到如下的语句时:

 Configuration configuration  =   new  Configuration();

出现了如下的错误,

 1 java.lang.IllegalAccessError: tried  to  access method net.sf.ehcache.CacheManager. < init > ()V  from  class org.hibernate.cache.EhCacheProvider

在网上找呀找,终于找到了,是ehcache的一个bug引起的,把ehcache升级到1.2以上的版本就行了,:0)
