... 27 more可以确定的是asm-3.3.jar已经添加，但是错误仍然存在请高手指教

Answer 1

解决办法是： 
去掉类路径上的关于Hibernate的3个lib 
asm.jar 
asm-attrs.jar 
cglib-2.1.3.jar 保留Spring中的以下4个lib 
asm-2.2.2.jar 
asm-commons-2.2.2.jar 
asm-util-2.2.2.jar 
cglib-nodep-2.1_3.jar 看看是不是jar冲突啦

Answer 2

你ASM版本太高了，你试下asm-2.2.2.jar，也可能是有多个asm包，导致冲突。

Answer 3

看文档的最后几行，有写。

Answer 4

第一次你说的asm.jar 
asm-attrs.jar 
cglib-2.1.3.jar
这三个jar包并没加，依旧出现问题。。并未整合spring

Answer 5

我只添加了一个asm-3.3jar包的

Answer 6

我这是hiberante和struts2的整合，⊙﹏⊙b汗
