经过查询之后发现除了要导入cglib的jar包之外还要导入asm的jar包，导入asm的jar包之后即可解决该问题。

cglib版本为3.0或3.1，org.objectweb.asm版本为3.1.0时
版本冲突，报错java.lang.IncompatibleClassChangeError: class net.sf.cglib.core.DebuggingClassWriter has interface org.objectweb.asm.ClassVisitor as super class
使用cglib 2.2 可解决此问题,该版本中的DebuggingClassWriter的父类为ClassWriter
