Provide IMMEDIATE session updates on a method level of RedisOperationsSessionRepository

[beku8]

We wanted to update the session, as new role granted for the user. We can achieve this with the combination of findByIndexNameAndIndexValue methond and by setting RedisOperationsSessionRepository on IMMEDIATE flush mode. Since we can't call save, due to the package access of RedisSession. But I think its not necessary to convert to IMMEDIATE just for this purpose.

Would it be possible to provide a method like setAttributeImmidiate(sessionId, name, value) on RedisOperationsSessionRepository?

Hi @beku8 - can you explain why you cannot call SessionRepository#save?

Hello, I tried to configure with

 @Autowired
  public UserSessionRefreshHandler(RedisOperationsSessionRepository sessionRepository,
      SessionRepository<Session> repository) {
    this.sessionRepository = sessionRepository;
  }

but it throws exception on the start up

Parameter 0 of constructor in com.nomadays.evento.UserSessionRefreshHandler required a bean of type 'org.springframework.session.SessionRepository' that could not be found.

'sessionRepository' not loaded because Session Condition found spring.session.store-type property REDIS

we are on spring boot 1.5.3, thus spring session 1.3.1.

I've tried with also couple of compinations of FindByIndexNameSessionRepository, RedisOperationsSessionRepository, SessionRepository. I thought they were somehow mutually exclusive.

But as you mentioned, I noticed that I autowired SessionRepository, in other classes successfully.

Any idea why this might be happening?

There are basically two ways you can inject a FindByIndexNameSessionRepository instance - either to inject and use raw type, or parameterized (respecting the original contract of FindByIndexNameSessionRepository<S extends Session>).

Raw type approach:

class RawConsumer {

	@Autowired
	private FindByIndexNameSessionRepository sessionRepository;

	void consume() {
		Session session = (Session) this.sessionRepository
				.findByIndexNameAndIndexValue(FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME, "principal")
				.values().iterator().next();
		session.setAttribute("test", UUID.randomUUID().toString());
		this.sessionRepository.save(session);
	}

}

Parameterized type approach:

class ParameterizedConsumer<S extends Session> {

	@Autowired
	private FindByIndexNameSessionRepository<S> sessionRepository;

	void consume() {
		S session = this.sessionRepository
				.findByIndexNameAndIndexValue(FindByIndexNameSessionRepository.PRINCIPAL_NAME_INDEX_NAME, "principal")
				.values().iterator().next();
		session.setAttribute("test", UUID.randomUUID().toString());
		this.sessionRepository.save(session);
	}

}

It works, and I feel stupid. Thanks :)
