Session + redis -> Lost data when run many requests

[schotten]

After migration to spring parent 2.5.0 from 3.4.0, the spring data redis lost data the intermittently.
I isolated one specific scenario that reproduce in my machine.

Enviroment:

1. I use the default Spring integration
2. I save the object complex in spring session through below code:

3. I use the last version of redis (7.4.1)

Scenario

My aplication execute the endpoint /front/adapters/grouper/23866860
After the response of backend, the front call the requests in parallel

• /front/constraints/list/disabled
• /front/user-requirements/user/forced/dto
• /front/tree
• /front/user-requirements/recommendation/disabled
• /front/tree/nodes/filter/autocomplete

In my secondary user interactive, i call the endpoint /front/drawings-urs[]

My problem:
When, i started the application in every firsty execution, the system lost data session in the parallel requests.
I created one LoggableDispatcherServlet to log session informations, please follow the file: LoggableDispatcherServlet.txt

In log from LoggableDispatcherServlet, please, check the order of request/response. I converted from table the better visualization

event	type	-	endpoint
1	IN	-	/front/adapters/grouper/23866860-urs[]
2	OUT	-	/front/adapters/grouper/23866860-urs[{"id"100,"keyUr":"Project.motor.hasBrake"}]
3	IN	-	/front/constraints/list/disabled-urs[]
4	IN	-	/front/user-requirements/user/forced/dto-urs[]
5	IN	-	/front/tree-urs[]
6	IN	-	/front/user-requirements/recommendation/disabled-urs[]
7	IN	-	/front/tree/nodes/filter/autocomplete-urs[]
8	OUT	-	/front/constraints/list/disabled-urs[]
9	OUT	-	/front/user-requirements/user/forced/dto-urs[]
10	OUT	-	/front/user-requirements/recommendation/disabled-urs[]
11	OUT	-	/front/tree-urs[]
12	IN	-	/front/projects/status/allStatus-urs[{"id"100,"keyUr":"Project.motor.hasBrake"}]
13	OUT	-	/front/projects/status/allStatus-urs[{"id"100,"keyUr":"Project.motor.hasBrake"}]
14	OUT	-	/front/tree/nodes/filter/autocomplete-urs[]
15	IN	-	/front/drawings-urs[]

Check:

• In the line 1, the user call the execution endpoint /front/adapters/grouper/23866860 and not have data in session.
• in the line 2, the system filled data in session ({"id"100,"keyUr":"Project.motor.hasBrake"})
• Lines 3,4,5,6,7 automatic called data from backand, after the response of line 2 and not have the session data in the start.
• Line 12 and 13 have session spring data
• line 15, the next interaction to user, the data was lost.

Please, verify and fix this problem, please. If need more information, please tell me in the response this question.

Spring Session and Spring Integration are separate projects. This repository hosts Spring Data Redis. I suggest you file in either one of these projects a ticket to get further guidance. It sounds as if Spring Session would be the better place to start with.
