How do I resolve error "No bean of type [io.micronaut.data.operations.PrimaryRepositoryOperations] exists" in micronaut application?

micronaut-data

I am evaluating micronaut and am attempting to port a small application as a pilot project. I have run into a snag dealing with datasources/repositories.

I have the following application.yml:

micronaut:
  application:
    name: bling-application

datasources:
  default:
    url: jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
    driverClassName: org.h2.Driver
    username: sa
    password: ''
    schema-generate: CREATE_DROP
    dialect: H2

jpa:
  default:
    entity-scan:
      packages: 'my.package.entity'
    properties:
      hibernate:
        bytecode:
          provider: none
        hbm2ddl:
          auto: update

I have defined a simple Repository interface as follows:

package my.package.entity.repository;

import my.package.entity.Company;
import io.micronaut.data.annotation.Repository;
import io.micronaut.data.repository.CrudRepository;

@Repository
public interface CompanyRepository extends CrudRepository<Company, Long> {

    Company findByName(String name);

}

When I run the application in test mode (./mvnw compile exec:exec) it starts without error. However, when I request an end-point that exercises the CompanyRepository I receive the following exception:

14:38:37.307 [pool-1-thread-4] ERROR i.m.h.s.netty.RoutingInBoundHandler - Unexpected error occurred: No backing RepositoryOperations configured for repository. Check your configuration and try again

Caused by: io.micronaut.context.exceptions.NoSuchBeanException: No bean of type [io.micronaut.data.operations.PrimaryRepositoryOperations] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

The stack trace says that something is missing from the application context (presumably PrimaryRepositoryOperations) but it is not clear to me what that is. How can I correct this error? I am new to micronaut and presume that I am missing some crucial dependency or configuration.

People also ask

How do you make a Micronaut Bean?

define and register beans in the application context. use built-in scopes. inject configuration to your application. automatically test your beans during application build with JUnit 5.

What is Micronaut data?

Micronaut Data is a database access toolkit that uses ahead-of-time (AoT) compilation to pre-compute queries for repository interfaces that are then executed by a thin, lightweight runtime layer. Since Micronaut Data does not do any query translation at runtime, the performance gain is significant.

What is the default error response body for Micronaut?

Micronaut produces error response bodies via beans of type ErrorResponseProcessor. The default response body is vnd.error, however you can create your own implementation of type ErrorResponseProcessorto control the responses.

Why can’t I debug beans in Micronaut?

This strategy leads to problems that are difficult to debug, for example: Bean loading order changes, leading to unexpected results A bean with the same name overrides another bean with a different type To avoid these problems, Micronaut’s DI has no concept of bean names or load order. Beans have a type and a Qualifier.

Is there A Micronaut Bean for nativeuserauthorization?

No bean of type [io.micronaut.data.operations.PrimaryRepositoryOperations] exists . @Singleton open class NativeUserAuthorization ( private val userService: UserServiceOperations): ApplicationEventListener<ServerStartupEvent> { override fun onApplicationEvent (event: ServerStartupEvent?) { // database access here } }

Does Micronaut’s Di support Bean names?

To avoid these problems, Micronaut’s DI has no concept of bean names or load order. Beans have a type and a Qualifier. You cannot override a bean of a completely different type with another.

I had the same error and it was caused by incorrect package name in the entity-scan property.

Like this sample:

jpa:
  default:
    entity-scan:
      packages: 'your.package.domain'

Okay, one more answer which maybe helpful in this particular case that I was facing. So I had a service which was not being injected after I applied the validation annotations. So, the fix as clearly mentioned on the docs page is:

https://docs.micronaut.io/snapshot/guide/index.html#datavalidation

For Gradle

implementation("io.micronaut.beanvalidation:micronaut-hibernate-validator")

For Maven:

<dependency>
    <groupId>io.micronaut.beanvalidation</groupId>
    <artifactId>micronaut-hibernate-validator</artifactId>
</dependency>

The problem was missing/conflicting dependencies in my pom file. To resolve I added this dependency:

    <dependency>
      <groupId>io.micronaut.configuration</groupId>
      <artifactId>micronaut-jdbc-tomcat</artifactId>
      <scope>runtime</scope>
    </dependency>

And removed this one:

    <dependency>
      <groupId>io.micronaut.configuration</groupId>
      <artifactId>micronaut-hibernate-jpa</artifactId>
      <scope>compile</scope>
    </dependency>
