Error with importing some classes while upgrading Spring-security-2.0.5 to Spring-security-4.2.0

Question

While upgrading spring security form version 2.0.5 to 4.2.0, I've got a problem with importing org.springframework.security.concurrent.ConcurrentLoginException; and org.springframework.security.ui.webapp.AuthenticationProcessingFilter; I searched many packages for these classes, but still can't find it.

Answer 1

As Tome wrote in comment, it is a quite big upgrade with many changes, but the classes you ask about:

• ConcurrentLoginException is replaced with org.springframework.security.web.SessionAuthenticationException.

• AuthenticationProcessingFilter is replaced with org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter.
