Spring Session REST

Spring Configuration

@EnableRedisHttpSession 
public class HttpSessionConfig {
	@Bean
	public LettuceConnectionFactory connectionFactory() {
		return new LettuceConnectionFactory(); 
	}

	@Bean
	public HttpSessionIdResolver httpSessionIdResolver() {
		return HeaderHttpSessionIdResolver.xAuthToken(); 
	}
}

We customize Spring Session’s HttpSession integration to use HTTP headers to convey the current session information instead of cookies.

Exploring the rest Sample Application

We have a header with the name of X-Auth-Token which contains a new session id

$ curl -v http://localhost:18096/header/hello -u user:password
$ curl -v http://localhost:18096/header/hello -H "X-Auth-Token: 4fee6933-18b9-4f60-bb24-55a15e51645e"
$ curl -v http://localhost:18096/header/findByUsername?username=user -H "X-Auth-Token: 4fee6933-18b9-4f60-bb24-55a15e51645e"
$ curl -v http://localhost:18096/header/logout -H "X-Auth-Token: 4fee6933-18b9-4f60-bb24-55a15e51645e"

How does it work?

Spring Security interacts with the standard HttpSession in SecurityContextPersistenceFilter.

Instead of using Tomcat’s HttpSession, Spring Security is now persisting the values in Redis. Spring Session creates a header named X-Auth-Token in your browser that contains the id of your session.
