解决：由于不同版本让我想到了可能会因为其它三方包是不同版本引起的最新的MyEclipse，所以里面的Hibernate也是最新的3.1（它里面还带有一个3.0版本的）
删除 多余的包 Hibernate3.1现象2：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in resource [/WEB-INF/dataAccessContext-hibernate.xml] of ServletContext: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager
java.lang.NoClassDefFoundError: javax/transaction/TransactionManager

原因：缺少jta.jar

Caused by: java.lang.SecurityException: class "org.springframework.beans.factory.support.GenericBeanDefinition"'s signer information does not match signer information of other classes in the same package

原因：jar包冲突,spring.jar和spring-core.jar冲突
解决：保留spring.jar,spring-web.jar,spring-context.jar
