How raj-priyanshu45/todo-app works
This Spring MVC application supports account signup and login, email-based OTP password recovery, and authenticated todo management. A browser submits requests through Spring Security and the controllers; controllers coordinate persistence or OTP verification and return JSP views or redirects. The todo path is directly supported by sampled controller, service, and repository code. Signup, reset, and authentication behavior is also sampled, but repository interfaces and application configuration are not, so database links represent their JPA persistence role and framework wiring is not expanded beyond the evidence.
