Adding ECS formatting to Quarkus

[nadworny]

Hi there,

I wanted to start a discussion about adding ECS formatting to the Quarkus framework. This issue describes what I was trying to achieve: https://github.com/quarkiverse/quarkus-logging-json/issues/132.

Now I have a working solution and was wondering how I can contribute to his library.

The solution consist of the following code which is based on your classes:

• Serializer: https://gist.github.com/nadworny/5fc96555c5f5d24c919fcacc482e820c
• Formatter: https://gist.github.com/nadworny/a80d405b4b4fc50f6e078ca14f451ab4

My EcsFormatter doesn't extend the Formatter class as it requires a slightly different approach namely it writes directly into the generator.

The final JsonProvider, which uses the quarkus-logging-json framework, looks like this:

@ApplicationScoped
public class EcsJsonProvider implements JsonProvider {

    private final EcsQuarkusFormatter ecsFormatter;

    @Inject
    public EcsJsonProvider(EcsConfiguration ecsConfiguration) {
        ecsFormatter = new EcsQuarkusFormatter(ecsConfiguration.service().name(), ecsConfiguration.service()
            .nodeName().orElse(null), Boolean.TRUE.equals(ecsConfiguration.logOrigin().orElse(null)),
            Boolean.TRUE.equals(ecsConfiguration.errorStackTraceAsArray().orElse(null)));
    }

    @Override
    public void writeTo(JsonGenerator generator, ExtLogRecord event) throws IOException {
        ecsFormatter.format(generator, event);
    }
}

Any suggestions/contributions how we could re-use my code and make it into this library would be greatly appreciated.
