Example For a Centralized Error Response Handling and a Custom Error Page in Quarkus

This is an example project for the article Centralized Error Response Handling and a Custom Error Page in Quarkus.

There are two subprojects, one for the global error response filter which can be started via:

./gradlew :global-error-response-filter:quarkusDev

and one for the global exception mapper, which can be started via:

./gradlew :global-exception-mapper:quarkusDev

If we now call the endpoint http://localhost:8080/bad-request, we can see that our custom error handling gets invoked. Also, the Accept header matching can be tested via:

> curl --header "Accept: text/plain" http://localhost:8080/forbidden
Error 403 (Forbidden)

Action not allowed.

> curl --header "Accept: application/json" http://localhost:8080/forbidden
[{"status":403,"title":"Forbidden","detail":"Action not allowed."}]

> curl --header "Accept: text/html" http://localhost:8080/forbidden
