Google oauth 및 Spring MVC를 사용하는 웹 애플리케이션에서 작업 해 왔습니다. 사용자가 Google oauth에 의해 인증 된 경우 사용자가 원하는 URL로 이동되는 google oauth를 구현했습니다. 이 기능을 달성하기 위해 Google GogleAuthHelper 클래스를 사용했습니다. 여기 내 코드가Google Oauth의 스프링 보안

ABove는 사용자를 인증하고 지정된 URL로 리디렉션하지만 그 후에는 응용 프로그램이 안전하지 않은 경우에 한 번 작동합니다. 내 응용 프로그램의 URL이 안전하지 않습니다. 이를 위해 Google은 oauth와 함께 봄 보안을 포함하고자합니다. 거기에 좋은 예가 있습니까? 나는 Google을 수색하고 성공하지 못했다. 나는 스프링 보안과 구글 oauth에 대한 좋은 예제를 원한다. 님의 도움에 감사드립니다.
감사합니다 !!!! –
