SpringBoot @JsonTest not found @JsonComponent in another module(as dependency)

Hello there! My project structure:

module: * common * api * use common as denpendency

I have a jackson config like below:

@JsonComponent
public class CustomCombinedSerializers {
  public static class MyZonedDateTimeSerializer extends ZonedDateTimeSerializer {
    protected MyZonedDateTimeSerializer() {
      super(DateTransformer.ISO_TIMESTAMP_FORMATTER);
    }
  }

  public static class MyLocalDateTimeSerializerSerializer extends LocalDateTimeSerializer {
    protected MyLocalDateTimeSerializerSerializer() {
      super(DateTransformer.ISO_TIMESTAMP_FORMATTER);
    }
  }

  public static class MyLocalDateTimeSerializerDeserializer extends LocalDateTimeDeserializer {
    protected MyLocalDateTimeSerializerDeserializer() {
      super(DateTransformer.ISO_TIMESTAMP_FORMATTER);
    }
  }
}

I want to reuse this CustomCombinedSerializers in both common and api module, cause they all need @jsontest slice tests. But I found that if I put CustomCombinedSerializers class in common module(specify package with @componentscan manully), @jsontest slice tests in api cannot load CustomCombinedSerializers class(jackson configuration not working). I move CustomCombinedSerializers class back to api module, it is working. Is there any method can address this problem?

specify package with @componentscan manully

It's hard to say what your test setup is or where the @ComponentScan directive is located. Please review the reference documentation. If you still need support, share a small sample that we can run ourselves to reproduces the problem.
