Document How to Use Custom sessionRepository with @EnableRedisHttpSessionConfiguration

[rwinch]

@EnableRedisHttpSessionConfiguration
public class HttpSessionConfig {
    @Value("${server.session-timeout}")
    private int maxInactiveIntervalInSeconds;

    @Primary
    @Bean
    public RedisOperationsSessionRepository sessionRepository(RedisTemplate<String, ExpiringSession> sessionRedisTemplate) {
        RedisOperationsSessionRepository sessionRepository = new RedisOperationsSessionRepository(sessionRedisTemplate);
        // customize
        sessionRepository.setDefaultMaxInactiveInterval(maxInactiveIntervalInSeconds);
        return sessionRepository;
    }
}

+1 looking in the docs for this only takes you to Gemfire. Also, it is strange that adding spring-session to Spring Boot autodetects everything, but the session timeout I had did not work.

Thanks for your work.

@dfernandezm Thanks for your comment.

Also, it is strange that adding spring-session to Spring Boot autodetects everything, but the session timeout I had did not work.

Can you elaborate on this problem? I think Boot uses session.timeout property to specify session timeouts with Spring Session.

@rwinch I defined server.session.timeout in application.yml, but that value was overwritten with the default provided by EnableRedisHttpSession's 1800. I was expecting server.session.timeout property to override the value in EnableRedisHttpSession. Is that unreasonable to expect? Is it a convention that property file values are overwritten with annotated configuration?

[rwinch]

@kamal2311 This is really a Boot question. However, in my experience as soon as you start providing any configuration of your own then Boot is suppose to back out of the way. What this means is that if you provide a @EnableRedisHttpSession, then the session.timeout will not be used for Spring Session. This makes sense because Boot no longer has access to the beans to modify the timeout.

@rwinch Thank you Rob. Can you help me with a Spring-Session Redis related question I have on stack overflow. [http://stackoverflow.com/questions/38510187/not-able-to-capture-sessiondestroyed-event-in-spring-redis-session-spring-boot]

So what is the proper way to use spring boot + spring-session-jdbc while getting the session timeout set with server.session.timeout without using @EnableJdbcHttpSession?

edit: The answer it seems is not to use the @EnableJdbcHttpSession annotation if you are expecting spring-boot to autoconfigure things (including the setting of server.session.timeout.

Simply add spring-session to your deps, then add to your props:

spring.session.store-type = jdbc

No annotation necessary.

This contradicts what the spring-session docs say about how to get started with spring boot.

@rwinch Where do you intend this documentation to live? Would it help to enhance https://github.com/spring-projects/spring-session/tree/master/samples/boot/redis to cover the customization use case(s)? I am happy to raise a PR if it helps. I am using RedisOperationsSessionRepository in a project and have got decent understanding of its configuration.
