[humanity]

打开 oracle 驱动的 jar 里面的 MANIFEST.MF 清单文件看，这个 jar 包是不是已经经过数字签名，并且 Sealed: true

如果 Sealed:true 那么这个 jar 里面的 java package 列表中的所有类，如果在这个 jar 文件之外也有其它类在这些 java package 中的话就会出错，再加上数字签名就能防止其它人弄一个类往你的 java package 名字空间里面混淆替换，篡改原来的 jar 文件。

你这个 CGLIB 增强在它看来属于篡改行为。

[humanity]

把这个 jar 解压后重新打包成不带签名和 sealed 试试看，反正你是自己用的，又不是像 Oracle 那样发布产品出去。

上面这个是MANIFEST.MF清单。

Sealed: true

下面我应该怎么做呢
