A basic Spring Security usage scenario: integrating with application user login/logou

[vw729]

I have a user login mechanism in place. And a user can have one or more roles based on my understanding of the Role definition within Spring Security.

public class User {

	public static String USER = "ROLE_USER", ADMIN ="ROLE_ADMIN";
...
	private Set<String> roles = new HashSet<String>();

	private String password;
	
	private String userName;
...
	public void addRole(String role) {
		roles.add(role);
	}
...
}

My question is how to integrate my application login/logout mechanism with Spring Security? I have looked through those samples linked to the sample and tutorial page and haven't seen a related sample.

Do I miss something for this basic case?
