            This guide should help you in creating your first Micronaut JDBC application.


            If you would like to use Lombok add it as a feature when you use either Micronaut CLI or Micronaut Launch.

            There are other guides and documentation that should help you on your journey.

            Answered 2021-Oct-28 at 05:27

            You declared mappedBy which defines who is the owner of the relationship, and in your case it’s Child, so you should have the parent assigned there.

            Answered 2020-Dec-08 at 18:11

            The problem is your package name - it should be com.rest.micronaut.entity, not com.rest.micronaut.Entity (similarly com.rest.micronaut.Model should be com.rest.micronaut.model). Package names should always be lowercase to avoid confusing package names with class and interface names.

            My guess is that Hibernate was assuming your class was a static inner class, so the generated HQL/SQL was incorrect.

            Kotlin, Micronaut and Hibernate custom bean validator is never called
            Asked 2020-Nov-27 at 01:01

            I'm studying Micronaut and Kotlin using gRPC for a project at work, and I've ran into some problems that I can't seem to find a answer to.

            I'm recriating some personal Spring projects in Micronaut using Kotlin. In those projects I create a custom bean validator annotation to verify if a parameter is duplicated or not. I've recriated it in Kotlin but it's never called, I've also debbuged the code, and it never stops at the breakpoints in the validator.

            Here's my Entity class that I want to validate. Note the @UniqueEmail annotation, that's my custom validator.



            Answered 2020-Nov-26 at 19:10

            UniqueEmailValidator should be a bean. It requires a @Singleton annotation.

            Is Micronaut Data with R2DBC a more scalable approach than classical “one thread per connection” model Micronaut Data JDBC
            Asked 2020-Nov-16 at 13:13

            According to micronaut-data reactive guide,

            "... In the case of reactive execution and if the backing implementation is blocking, Micronaut Data will use the Configured I/O thread pool to schedule the query execution on a different thread.

            If the backing implementation natively supports reactive types at the driver level then the I/O thread pool is not used and instead it is assumed the driver will handle the query in a non-blocking manner..."

            My straight question: accessing a Relational Database (eg. PostGres R2DBC driver) throw R2DBC will Micronaut Data rely that R2DBC driver will handle in a non-blocking manner and be more scalable?

            Supposing my microservice expose a Reactive endpoint based on ReactiveX and has to access a blocking data source throw Micronaut Data JDBC (eg. there isn't yet Oracle R2DBC in production version), it is clear from above that it "will use the configure I/O thread pool" while accessing data. Am I losing totally the benefits o Reactive endpoint?

            It is my first project with Micronaut and I have few ones with Reactive approach. I am far to be an expert in Reactive best practices but I remenber have read in several blogs: avoid use reactive stack if you have blocking source. I also remember read that you can have worse result mixing non-blocking with blocking design mainly because the way Eventloop (eg. Netty) is designed. Since I will use Micronaut with ReactiveX and Relational Database, some cases with R2DBC and others with JDBC, I will gratefull any comment on my doubt.



            Answered 2020-Nov-16 at 13:13

            You are not entirely losing the benefits since if you have HTTP requests that are not blocking you can compose those operations with your JDBC logic.

            However if you want true non-blocking with R2DBC see https://github.com/micronaut-projects/micronaut-r2dbc/

            You need to reload Gradle project after changing build script. Use "Reload all Gradle projects" button in Gradle tool window (two cycled arrows).
