DBeaver是什么不用我多介绍了吧，在zhile上也能找到激活的法子，刚好前些天研究了一下ja-netfilter以及power插件，我寻思这个DBeaver的授权也是rsa，何不直接使用ja-netfilter呢？这样就不用始皇的dbeaver-agent了，说干就干。
懒得写分析过程了，直接贴码（用到了我自己写的第三方库crypto_plus，求个star 
）：

dbeaver版本更新后，修改license中的product即可，默认会生成ue激活码，ue&ee均可使用，将打印的patch内容粘贴到power.conf的[Args]标签下，由于ue，ee的公钥相同，所以只需要粘贴一行即可通杀。
dbeaver.ini末尾增加：
-Dlm.debug.mode=true
--add-opens=java.base/jdk.internal.org.objectweb.asm=ALL-UNNAMED
--add-opens=java.base/jdk.internal.org.objectweb.asm.tree=ALL-UNNAMED
-javaagent:/path/to/ja-netfilter.jar=jetbrains
顺便贴一个dbeaver ue/ee的公钥 (1022 字节)，也可以自行提取，需要解压后放到python脚本同级目录，这样就可以自由的修改授权信息了 
最后求个免费的赞
