spring mvc - Encrypt JAVA SpringFramework WebApplication -


i've created springframework webapplication , want distribute it. client asked me evaluate applications on own server. want protect code encrypting source. possible? if yes, what's best tool? there performance loss using it?

notice variables based on injection annotations should declared private, otherwise won't injected correctly after process of proguard.

1. proguard

2. apache ant
