以上是我的web项目发布时抛出的异常，我在网上查询了有关问题，说是jar包的冲突导致，但我实在没弄明白该怎么解决，在这里寻求解决方案......

看看 sessionFactory 对应的bean 的class路径 是否存在多个呢？如果有多个，就去掉一个不用的

[roxliu]

cglib和asm包版本冲突。 错误信息中： Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V cglib中使用了asm org.objectweb.asm.ClassVisitor.visit(), asm包中没有这个函数，或者是函数的参数不匹配。

[长笛党希望]

cglib和asm包发生冲突 楼主可以查看这个链接http://blog.csdn.net/lyd518/article/details/2747766 应该是个完美解决方案。
