UPDATE:
This issue was present in Spring Data Commons releases 1.11.6/1.12.6 and was fixed in 1.11.7/1.12.7/1.13/2.0.
See DATACMNS-776.
This is a minimal project to demonstrate error that occurs when using Spring Security together with Spring Data.
The cause of this issue is DATACMNS-776. This project
demonstrates the problem with Spring Security's @AuthenticationPrincipal annotated UserDetails
argument and CsrfToken argument.
To demonstrate the issue, build and start the application, and log in using username user and
password password. Once logged in, navigate to /principal and /csrf endpoints.
If the project is build with org.springframework.boot:spring-boot-starter-data-jpa dependency
commented out from the build script, the endpoints work as expected.
