Spring2.5 配置Hibernate3.3 EhCache 配置错误解决方法

见下面问题：

Invocation of init method failed; nested exception is java.lang.IllegalAccessError: tried to access method net.sf.ehcache.CacheManager.<init>(Ljava/net/URL;)V from class org.hibernate.cache.EhCacheProvider

2010-04-10 16:47:54 [main:6484] - [ERROR] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [E:\help\soft\tomcat\tomcat-5.5\webapps\wyw\WEB-INF\classes\applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalAccessError: tried to access method net.sf.ehcache.CacheManager.<init>(Ljava/net/URL;)V from class org.hibernate.cache.EhCacheProvider

从这面的问题看，是因为配置EhCache错误，找到源码后，调试发现，有的类没有引进来，仔细查看是发现，原来我导入lib下的类为ehcache-1.2.3.jar，而现在调用的类却是来自与Hibernate 3.1 Core Liberries引用lib下的ehcache 1.1.jar.现在问题终于弄清楚了，在网上找了相关问题的解决方法，很多都是与包有关，但是遇到这种问题还是第一次。做一个标记，下次遇到类似问题切记仔细。
