Hey guys, with latest Micronaut version 2.1.2, we noticed that creating ApplicationContext within a test and replacing application bean with a mock bean using registerSingleton method of context creates two beans with same underlying mock instance, opened an issue here: micronaut-projects/micronaut-core#4420 yesterday.

This was working fine with previous version we used: 2.0.3

Hi, moving from grails to micronaut + nuxt, I'd love to use GORM in production but I see it has "preview" in the name. When do you think it will be safe to use it?

James Kleeh

@jameskleeh

Its preview because its a milestone release I believe. We needed to use the milestone because of Groovy 3

It will be out of preview once a 7.1.0 release is out there

In general I wouldn’t be that concerned, but that is just my opinion

Sebastian Lillo Navarro

@slillo-coriolis_gitlab

Thanks James, I'll give it a try

Anyone has run into java.lang.IllegalStateException: cannot send more responses than request before?

I got that after upgrading to 2.2.0.

Hello Guys,,, . In Springboot, just by adding sleuth dependency , we can see 'traceId' and 'spanId' in STS console. I am trying to mimic similar functionality in micronaut using Intellij . I tried injecting dependency implementation "io.micronaut:micronaut-tracing" along with use of annotation 'io.micronaut.http.annotation.NewSpan' at controller. But i am not able to see 'traceId' in Intelli console ? do i have to override logback.xml file ?

@abhikumarblume You will need a reporter for this, it's possible to have your own custom zipkin2.reporter.Sender as per the docs https://docs.micronaut.io/latest/guide/index.html#zipkin on the "Customizing Zipkin" section

add the libraries and provide a Bean of type "Sender"

Hi,

I try to update micronaut in the-benchmarker/web-frameworks#3592 for a benchmarking project. Since I'm not a java guy, could somebody check the implementation in https://github.com/the-benchmarker/web-frameworks/tree/master/java/micronaut

But i am not able to see 'traceId' in Intelli console ? do i have to override logback.xml file ?

For micronaut 2.2.1, i was able to get 'X-B3-TraceId' in ResponseHeader and logs by adding below code: - 1) logback.xml <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<withJansi>false</withJansi>

<encoder>
<pattern>%cyan(%d{HH:mm:ss.SSS}) %gray([%thread]) %highlight(%-5level) %magenta(%logger{36}) - [%X{X-B3-TraceId:-},%X{X-B3-SpanId:-}] %msg%n</pattern>
</encoder>
</appender>
2) build.gradle
implementation "io.micronaut:micronaut-tracing"
implementation 'io.opentracing.brave:brave-opentracing' 3) application.yml tracing:
zipkin:
enabled: true My project has KafkaListner. 1 weird issue which i saw was if i annotate my class with @kafkaListner then response header doesnot contain 'X-B3-TraceId'. When i move to to methodlevel then response header contains 'X-B3-TraceId'.

Hi! Is it possible to add retrying for connection for @RabbitListener? I have a situation when my service is started, but Rabbit MQ is not yet.
Currently, I try to hack RabbitConnectionFactory by replacing it with my @Factory which tries to connect with N attempts.

James Kleeh

@jameskleeh

Is that not working for you?

Aleksandr Izmaylov

@zinoviy23

It works but looks like a hack

Hello all, I’m using declarative http client in micronaut to get call a REST web service.
As per the documentation, I can declare my httpclient as -
HttpResponse<Pet> getData(some query parameter);

Now I have two subclasses of Pet - Let’s say Dog and Cat having their specific member variables respectively

Now when my app calls this service it is returning an instance of Dog or Cat with Dog or cat attributes, such child object specific information(state of Dog or Cat) is getting lost at client side as return type is ‘Pet’…

can anyone assist here - would like to know How I can leverage httpclient to get child objects as response even though the declarative client is of parent type

I’m able to get memeber variables only which is declared in Pet class

James Kleeh

@jameskleeh

@mohit2491 you have to inform Jackson how to deserialize the json

Mohit Gupta

@mohit2491

@jameskleeh thanks for your inputs. It worked.

How do I register a jackson module in micronaut?

James Kleeh

@jameskleeh

just make it a bean

keenz

@kindlychung

For example I'd like to do this:

mapper.registerModule(new VavrModule());

for all the mappers.

@jameskleeh so in this case i need to make a VavrModule a bean?

James Kleeh

@jameskleeh

is VavrModule your class?

keenz

@kindlychung

no.

James Kleeh

@jameskleeh

It should be added automatically

@kindlychung

ah, great, so there is nothing to do about it?

James Kleeh

@jameskleeh

Hello, I seem to be stumbling across this issue oracle/graal#2742 with the Micronaut 2.2.x versions. The previous 2.1.x versions don't have this issue.
