struts2是自己导进去的，一共7个包，是2.1.6版
hibernate是由MyEclipse生成的，Spring也是，hibernate是3.2版，spring是2.5版

我大致分析出了问题是在Hibernate映射文件上，我把hibernate的
<mapping resource="com/accp/entity/SysBook.hbm.xml" />去掉就一点问题都没有了
但是对应的映射文件也没问题啊，并且是自动生成的，而且我换其他的映射也出现这样的问题，我想会不会是jar包冲突，我在网上找了好多方法，都没用，不管是说什么缺少javassist.jar(这个我有)，还是说asm有问题，我都试过了，无效，请大家帮帮忙啊。这个问题太纠结了
