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

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

[beautyOfJava]

[Quote=引用 1 楼 的回复:]

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……

我只添加了一个asm-3.3jar包的

[阿甘1976]

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。
