Strange behavior when adding spring boot starter & testcontainers

Open salaboy opened this issue 6 months ago • 12 comments

Description of the bug

Hi folks, I am trying to create a simple example of vaadin and testcontainers, in this case using Redis and Spring Data Redis:

https://github.com/salaboy/vaadin-demo

For some reason, when I start this app, vaadin goes into a loop (in the browser). I've checked the configurations several times, but I am sure I am missing something.

Image

I've excluded hilla, and I am running the app with mvn spring-boot:test-run as I want the test configuration to start when I start my app.

Expected behavior

The app starts and I can create my UI :)

The most likely cause is the spring-session-date-redis dependency, causing for some reason a sessionExpired message on the first UIDL request from Flow client. If you replace it with spring-data-redis the application starts.

Then there's another issue in ProductCatalogUI constructor: you are using field injection for productService but trying to use in the constructor, resulting in a NullPointerException. Using constructor injection would solve this problem.

And, looking at the posted logs, you might also have some issues with docker configuration, since it seems it is not running on your machine or the application is not properly configured (DOCKER_HOST tcp://127.0.0.1:53210 is not listening).

@mcollovati, do you have any example with spring data redis somewhere that I can look at ?

I'm sorry: nothing comes to my mind. But just replacing the dependencies org.springframework.session:spring-session-date-redis with org.springframework.data:spring-data-redis should be enough, and autoconfiguration should happen in the same way it does with the Spring Session Data Redis dependency.

mcollovati avatar Jun 09 '25 06:06 mcollovati

I will give that a try

@mcollovati after giving this a try again, I keep hitting issues with: "spring-session-data-redis". Spring Data Redis works as expected but there is definitely wrong with "spring-session-data-redis", Looking around it seems that this is a long standing issue. Trying to store the HTTP session for Vaadin applications seems to be an unresolved issue.

As you said, it is known that Spring Session is not playing well out-of-the-box with Vaadin because of how Spring Session works. Here are some additional details (maybe not up to date since the comment was from a couple of years ago) https://github.com/vaadin/kubernetes-kit/issues/4#issuecomment-1276004678

It might work with some configurations, but if PUSH is enabled, there will most likely be some issues.

mcollovati avatar Jun 14 '25 10:06 mcollovati

It will be very useful to get some idea of what configurations. I started thinking that maybe I can create a testing profile where I just test the endpoints to see if we remove vaadin from the equation that works.

It should basically be what is described in the linked Kubernets Kit issue comment. But I did not try it recently.

Marco, can you link the comment that you are reffering too?

Looks like the same as this https://github.com/vaadin/flow/issues/4746.
