Java sec code is a very powerful and friendly project for learning Java vulnerability code.

Alibaba-Security attack and defense/research（P5-P7）

This project can also be called Java vulnerability code.

Each vulnerability type code has a security vulnerability by default unless there is no vulnerability. The relevant fix code is in the comments or code. Specifically, you can view each vulnerability code and comments.

Due to the server expiration, the online demo site had to go offline.
