解决:
解决:在commons-collections-2.1.1.jar包中找到了LRUMap.class文件但他没在map文件夹下而是直接放在了collections下。后来换了个包commons-collections-3.1.jar.问题解决。

java.lang.NoClassDefFoundError: javax/persistence/spi/ProviderUtil
错误原因以及解决方法:
使用了hibernate3.5以上的版本,这些需要导入一个包:
hibernate-jpa-2.0-api-1.0.0-CR-1.jar
5.
java.lang.NoSuchMethodError: org.slf4j.helpers.MessageFormatter.format
包冲突:
使用以下包,将多的删除!
