Spring "Cache miss for REQUEST dispatch to '/admin' error caused

Affects: Springboot 3.2.0

I am currently using Spring Security. However, when accessing the admin page, the error log written below occurs and 404 Not Found error occurs for all pages. May I know what's causing this?

Error Log

The error log is related to https://github.com/spring-projects/spring-security/issues/14128.

The 404 issue is completely independent. Is there a controller mapped at this endpoint? Can you share a minimal sample that demonstrates this?

sure! this is controller code.

Controller

@Controller
@RequiredArgsConstructor(access = AccessLevel.PROTECTED)
public class ApplicantController {
    private final ApplicantService applicantService;

    @GetMapping("/admin")
    public String moveAdminPage(Model model) {
        model.addAttribute("applicants", applicantService.findAllApplicantInfo());
        return "admin";
    }

This code snippet should work, there might be a problem somewhere else. Can you share a sample project?

404 error is expected, I'm not seeing any controller in the project.

oh I'm really sorry.. i was implementing a feature in the feat/#1 branch, not the main branch. I forgot to explan this.

I can't reproduce the problem. Running with a the "local" profile and accessing http://localhost:8080/admin (after entering credentials) works for me.

To explain this problem in more detail, Problems occurred when the spring boot application was restarted without closing the browser that accessed the 'http://localhost:8080/admin' url.

Sorry but I can't spend more time on this. We use this issue tracker for enhancement requests and bug reports. It seems you're describing the fact that the authentication session is not persisted between app restarts. There are projects dedicated to solving that, like Spring Session. For further questions, please use StackOverflow.
