今天刚搭建的JPA(hibernate4.1)+spring 3.1+struts2.3.8环境，遇到了下面异常，查看对比了hibernate3和hibernate4的区别，发现hibernate4是删除了util包，所以说应该hibernate4的话，应该不用下面那个类，求解释！

网上有说：hibernate.annotation.jar不需要，但是我也没导入啊，值导入了：hibernate.common-annotation.jar这个应该没问题！

请大神指教！！！谢谢

少包了

------解决思路----------------------
请问LZ这个问题怎么解决的？
------解决思路----------------------
你把不需要的包统统删掉就好了！！！！！
那是因为用了JPA(hibernate4.1)+spring 3.1+struts2.3.8 之前版本的包。我直接覆盖原来低版本的包，竟是包错。还不如搭建新环境了。
------解决思路----------------------
找这个类org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean
所在jar版本是不是不兼容
------解决思路----------------------
hibernate4 的org.springframework.orm.hibernate4.LocalSessionFactoryBean是直接支持annotation的所以你不需要导入hibernate.annotation.jar如果你导入了这个包就会包这个错误了。hibernate4需要导入的包：
antlr-2.7.7.jar
c3p0-0.9.2.1.jar(因为我使用的c3p0去连接数据库的)
dom4j-1.6.1.jar
hibernate-c3p0-4.2.3.Final.jar(使用c3p0去连接数据库连接池)
hibernate-commons-annotations-4.0.2.Final.jar
hibernate-core-4.2.3.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.1.Final.jar
mchange-commons-java-0.2.3.4.jar
