我已将cglib-nodep-2.2.3 .jar放入我的web-inf / lib文件夹中，但我仍然会收到相同的错误。不知道为什么这个班在那里呢。

解决方案

此问题是由于不包括asm依赖关系引起的cglib有。

解决方案1：将正确版本的asm和asm-util添加到您的类路径中

解决方案2：使用cglib-nodep版本（其中包括asm依赖项）。

I've placed cglib-nodep-2.2.3 .jar into my web-inf/lib folder but I'm continuing to get the same error. Not sure why as the class is there in the jar. I get the same error message whether or not the jar is there.

解决方案

This problem is caused by not including the asm dependencies that cglib has.

Solution 1: Add the correct versions of asm and asm-util to your classpath

Solution 2: Use the cglib-nodep version (which includes both asm dependencies).
