Auto-configure not working when using @SpringBootApplication

[echoesbr]

Description

The library is not initialised when using the annotation @SpringBootApplication(exclude = ErrorMvcAutoConfiguration.class)

Expected Behavior

The expected behaviour should be the default error response from the library.

Actual Behavior

The default Spring boot response is returned (empty).

Steps to Reproduce

1. Added library
   <dependency> <groupId>org.zalando</groupId> <artifactId>problem-spring-web-starter</artifactId> <version>0.27.0</version> </dependency>

2. Configure Spring boot
   web: resources: add-mappings: false mvc: throw-exception-if-no-handler-found: true

3. Used annotation
   @SpringBootApplication(exclude = ErrorMvcAutoConfiguration.class)

4. Alternatively tried with following without success
   @EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class}) @Configuration @ComponentScan(basePackages = "com.foo.bar") @SpringBootConfiguration

Your Environment

• Version used: 0.27.0
• Spring Boot version: 2.6.6

Realised that my application already had a @ControllerAdvice class, so the one from the library was not being instantiated. Maybe worth mentioning in the docs.

I had the same issue 😖

I have to be honest, I'm still not sure if I must configure @EnableAutoConfiguration when using the problem-spring-web-starter on pom.xml.

When I add the following config:

@EnableAutoConfiguration(exclude = ErrorMvcAutoConfiguration.class)

And there's any @ControllerAdvice in the application, like this one:

@ControllerAdvice
public class ResponseStatusExceptionHandler implements ResponseStatusAdviceTrait {

    @Override
    public ProblemBuilder prepare(Throwable throwable, StatusType status, URI type) {
        ResponseStatusException exception = (ResponseStatusException) throwable;
        return Problem.builder()
                .withTitle(status.getReasonPhrase())
                .withStatus(status)
                .withDetail(exception.getReason())
                ;
    }
}

Everything stopped working.

But if I disable the ResponseStatusExceptionHandler (like commenting the annotation out) everything works again!

Could you guys give us any help?
