My endpoint is available here http://coin-traders-api.herokuapp.com/oauth/token. HTTP Message converters to convert the return value to HTTP response body, based The findCities() method returns a list of cities as The key difference between @RequestParam and @PathVariable is that @RequestParam used for accessing the values of the query parameters where as @PathVariable used for accessing the values from the URI template. We created a custom Authentication implementation to enrich the SecurityContext with more data. All I was saying, I would've expected to see.

In the following application, we demonstrate the usage of ResponseEntity. Depending on your configuration, it may or may not find any. You can see in the console logs from the server startup which endpoints are provided out of the box.

It provides a clear and explicit way to convey the message that there may not be a value, without using null. You can run the application from the command line with Gradle or Maven. ResponseEntity represents an HTTP response, including headers, body, and status.

an example project is https://github.com/ministryofjustice/hmpps-spring-boot-2.6-bug, if you run ./gradlew test then it will fail, the branch https://github.com/ministryofjustice/hmpps-spring-boot-2.6-bug/tree/previous-working-version shows it working in the previous version of spring boot 2.5.6 alternately allowlisting /error fixes it too ( but we don't want to allowlist /error ).

When using basic authentication, the authentication from the initial request is reinstated when the request fails and is forwarded to Boot's error page: By contrast, when using a bearer token, the forward to /error is done with an anonymous authentication rather than the AuthAwareAuthenticationToken that was initially established: The newly introduced ErrorPageSecurityFilter is built on the assumption that Spring Security will behave consistently in terms of the authentication that's available when a request is forwarded. Your method implementation is ambiguous, try the following , edited your code a little bit and used HttpStatus.NO_CONTENT i.e 204 No Content as Spring is a popular Java application framework and Spring Boot Instead you can remove the annotation from the EmptyJsonResponse, and just make it the @ResponseBody for your method.
