SSH配置启动后Tomcat后报错：Could not instantiate bean class [org.hibernate.cfg.Configuration]

SSH配置启动后Tomcat后，报错：Could not instantiate bean class [org.hibernate.cfg.Configuration]:

 

解决方法：
用rar打开 hibernate3.jar，里面已经包含annotations相关包，与老版本冲突。
解决的方法：将lib目录下的： hibernate-annotations.jar 和 hibernate-commons-annotations.jar 删除后重新部署可。

 

==============================================================================

网上查找了原因，原来要到tomcat里的webapps里删掉项目的hibernate-annotations.jar；hibernate-commons-annotations.jar；保留hibernate3.jar就行了。

 

但是由于在user libraries去掉冲突的jar之后，重启服务还是报一样的错误，这个因为Tomcat Server的webapps目录下的工程里的lib目录下的仍存在冲突的jar文件，所以导致重启之后还是报一样的错误，

解决办法：Tomcat Server删除部署，重新部署一遍就没问题了

报错信息如下：
