Why #MockBean ConversionService causes an error - spring-boot

Given: JUnit 5 and empty SpringBoot project created with Intellij IDEA Ultimate. I get the same results for projects with a controller that contains #Autowired ConversionService.
I need to use in a test the mocked version of ConversionService.
This is my approach:
import org.junit.jupiter.api.Test;
import org.mockito.Mock;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.core.convert.ConversionService;
#SpringBootTest
public class ConversionServiceTest {
#MockBean
ConversionService conversionService;
#Test
void test() {}
}
The above code causes the error:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.format.support.FormattingConversionService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Qualifier(value="mvcConversionService")}
What is the reason for this error and what is the solution?

The solution is to replace #MockBean by #SpyBean.

JUnit #DataJpaTest org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

I'm trying to do a test on the repository using #DataJPATest but #Autowired is not working
I already tried looking for examples of junit5 with #DataJpaTest, but I didn't find it
I tried adding other dependencies, I used #SpringTest and it worked, but I wanted to use #DataJpaTest

I managed to solve it, I updated spring to version 2.7.5 and I verified that the test dependency was not downloading correctly, I redid the pom.xml and it worked.

Spring Boot Test fails to load application context with JUnit 5 for a custom integration test source set

I'd like to start with some integration tests for my spring boot backend service. Therefore I added a gradle plugin that helps me adding the integrationTest source set.
// build.gradle.kts
plugins {
id("org.springframework.boot") version "2.4.2"
id("io.spring.dependency-management") version "1.0.11.RELEASE"
id("org.jlleitschuh.gradle.ktlint") version "9.4.1"
id("org.unbroken-dome.test-sets") version "3.0.1" // <<
kotlin("jvm") version "1.4.21"
kotlin("plugin.spring") version "1.4.21"
}
...
dependencies {
testImplementation("org.springframework.boot:spring-boot-starter-test")
}
...
testSets {
create("integrationTest")
}
...
Then I started building my first test spec:
// TeamApiIntegrationTest.kt
package com.myapp.integrationtest.api
import com.myapp.userservice.repository.TeamRepository
import org.assertj.core.api.Assertions.assertThat
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.ExtendWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.test.context.ContextConfiguration
import org.springframework.test.context.junit.jupiter.SpringExtension
#SpringBootTest
#ContextConfiguration(classes = [TeamRepository::class])
#ExtendWith(SpringExtension::class)
class TeamApiIntegrationTest #Autowired constructor(
private val teamRepository: TeamRepository
) {
#Test
fun `should fetch a list of two teams where the current auth user is part of`() {
assertThat(teamRepository).isNotNull
}
}
The exception I receive is this one:
Failed to resolve parameter [com.myapp.userservice.repository.TeamRepository teamRepository] in constructor [public com.myapp.integrationtest.api.TeamApiIntegrationTest(com.myapp.userservice.repository.TeamRepository)]: No qualifying bean of type 'com.myapp.userservice.repository.TeamRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Dependency annotations: {}
[...]
I understand the problem but don't know why it occurs since I am explictly "adding" TeamRepository to the ContextConfiguration.
EDIT:
// TeamRepository.kt
import org.springframework.data.repository.PagingAndSortingRepository
import org.springframework.stereotype.Repository
#Repository()
interface TeamRepository : PagingAndSortingRepository<Team, String> {
fun findByName(name: String): List<Team?>
fun findByUsers(user: User): List<Team?>
}
You need to remove the #SpringBootTest.
#SpringBootTest will look for actual configuration with Junit 5.
I have faced the same issue earlier in java

Spring Boot 2.0.0.M2 and Spring Data Elasticsearch configuration

I'm trying to move my project to Spring Boot 2.0.0.M2.
This is my old Spring Data Elasticsearch configuration:
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;
import org.springframework.data.elasticsearch.core.ElasticsearchOperations;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;
#Profile("production")
#Configuration
#EnableElasticsearchRepositories(basePackages = "com.example.domain.repository.elasticsearch")
public class ElasticsearchConfig {
#Value("${elasticsearch.host}")
private String host;
#Value("${elasticsearch.port}")
private int port;
#Bean
public Client client() throws Exception {
return TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(host), port));
}
#Bean
public ElasticsearchOperations elasticsearchTemplate() throws Exception {
return new ElasticsearchTemplate(client());
}
}
Right now I faced a following issue:
1. The method builder() is undefined for the type TransportClient
2. InetSocketTransportAddress cannot be resolved to a type
On the Maven classpath I have Spring Data Elasticsearch 3.0.0.M4:
How to properly configure current version of Spring Data Elasticsearch ?
UPDATED
For my tests I use Embedded Elasticsearch with a following application.properties:
#Elasticsearch
spring.data.elasticsearch.properties.http.enabled=true
spring.data.elasticsearch.properties.http.port=9250
spring.data.elasticsearch.properties.path.home=target/test-elasticsearch-db
spring.data.elasticsearch.properties.transport.tcp.connect_timeout=60s
This is my ES test config:
#Profile("test")
#Configuration
#EnableElasticsearchRepositories(basePackages = "com.example.domain.repository.elasticsearch")
public class ElasticsearchTestConfig {
}
Right now the test fails with a following error:

What is wrong here and how to fix this ?
Spring Boot 2.0 uses Elasticsearch 5 which includes some breaking API changes. You would be shielded from those changes if you used Spring Boot's auto-configuration rather than trying to write your own.
All that's needed is a value for the spring.data.elasticsearch.cluster-nodes property. With that in place, Spring Boot will auto-configure both a TransportClient and an ElasticsearchTemplate.
Had similar issue when migrating from spring-boot 1.5.6 to 2.0.0. The reason seems to be previous support for embedded elasticsearch is not more supported and the same is reflected in spring-boot.
Previously leaving the following property empty
spring.data.elasticsearch.cluster-nodes
put the following into use
spring.data.elasticsearch.properties.path.home
and spring-boot created given directory in the target folder for embedded mode to run. With spring-boot 2.0.0 (spring-boot-autoconfigure-2.0.0.RELEASE.jar to be precise) cluster-nodes has become asserted for non-null value causing elasticsearchTemplate bean not to be created under the hood.
That is the reason why your app stop working so suddenly.

I'm not seeing your repository annotated. That might be the reason why Spring couldn't create a bean for MyRepository during component scan. Annotate it with #Repository

I even compared my code with Accessing data jpa, and I'm running out of ideas what's wrong with this code.
Any help appreciated.
EDITED: I changed my code as suggested to look like above, and I'm not getting that error when I'm injecting my #Repository interface into another component. However, I have a problem now - my component cannot be retrieved (I used debugging). What I'm doing wrong so spring cannot find my component?
When the repository package is different to #SpringBootApplication/#EnableAutoConfiguration, base package of #EnableJpaRepositories is required to be defined explicitly.
Try to add #EnableJpaRepositories("com.pharmacy.persistence.users.dao") to SpringBootRunner
I had the same issues with Repository not being found. So what I did was to move everything into 1 package. And this worked meaning that there was nothing wrong with my code. I moved the Repos & Entities into another package and added the following to SpringApplication class.
#EnableJpaRepositories("com...jpa")
#EntityScan("com...jpa")
After that, I moved the Service (interface & implementation) to another package and added the following to SpringApplication class.
#ComponentScan("com...service")
This solved my issues.
There is another cause for this type of problem what I would like to share, because I struggle in this problem for some time and I could't find any answer on SO.
In a repository like:
#Repository
public interface UserEntityDao extends CrudRepository<UserEntity, Long>{
}
If your entity UserEntity does not have the #Entity annotation on the class, you will have the same error.
This error is confusing for this case, because you focus on trying to resolve the problem about Spring not found the Repository but the problem is the entity. And if you came to this answer trying to test your Repository, this answer may help you.
It seems your #ComponentScan annotation is not set properly.
Try :
#ComponentScan(basePackages = {"com.pharmacy"})
Actually you do not need the component scan if you have your main class at the top of the structure, for example directly under com.pharmacy package.
Also, you don't need both
#SpringBootApplication
#EnableAutoConfiguration
The #SpringBootApplication annotation includes #EnableAutoConfiguration by default.
I had a similar issue where I was receiving NoSuchBeanDefinitionException in Spring Boot (basically while working on CRUD repository), I had to put the below annotations on the main class:
#SpringBootApplication
#EnableAutoConfiguration
#ComponentScan(basePackages={"<base package name>"})
#EnableJpaRepositories(basePackages="<repository package name>")
#EnableTransactionManagement
#EntityScan(basePackages="<entity package name>")
Also, make sure you have the #Component annotations in place on the implementations.
In SpringBoot, the JpaRepository are not auto-enabled by default. You have to explicitly add
#EnableJpaRepositories("packages")
#EntityScan("packages")
#SpringBootApplication(scanBasePackages=,<youur package name>)
#EnableJpaRepositories(<you jpa repo package>)
#EntityScan(<your entity package>)
Entity class like below
#Entity
#Table(name="USER")
public class User {
#Id
#GeneratedValue
To extend onto above answers, You can actually add more than one package in your EnableJPARepositories tag, so that you won't run into "Object not mapped" error after only specifying the repository package.
#SpringBootApplication
#EnableJpaRepositories(basePackages = {"com.test.model", "com.test.repository"})
public class SpringBootApplication{
}
It could be to do with the package you have it in. I had a similar problem:
Description:
Field userRepo in com.App.AppApplication required a bean of type 'repository.UserRepository' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'repository.UserRepository' in your configuration.
"
Solved it by put the repository files into a package with standardised naming convention:
e.g. com.app.Todo (for main domain files)
and
com.app.Todo.repository (for repository files)
That way, spring knows where to go looking for the repositories, else things get confusing really fast. :)
Hope this helps.
You are scanning the wrong package:
#ComponentScan("**org**.pharmacy")
Where as it should be:
#ComponentScan("**com**.pharmacy")
Since your package names start with com and not org.
I had some problems with this topic too.
You have to make sure you define the packages in Spring boot runner class like this example below:
#SpringBootApplication
#EnableAutoConfiguration
#ComponentScan({"controller", "service"})
#EntityScan("entity")
#EnableJpaRepositories("repository")
public class Application {
public static void main(String[] args){
SpringApplication.run(Application.class, args);
}
I hope this helps!
Here is the mistake: as someone said before, you are using org.pharmacy insted of com.pharmacy in componentscan
package **com**.pharmacy.config;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan("**org**.pharmacy")
public class SpringBootRunner {
If you're facing this problem when unit testing with #DataJpaTest then you'll find the solution below.
Spring boot do not initialize #Repository beans for #DataJpaTest. So try one of the two fix below to have them available:
First
Use #SpringBootTest instead. But this will boot up the whole application context.
Second(Better solutions)
Import the specific repository you need, like below
#DataJpaTest
#Import(MyRepository.class)
public class MyRepositoryTest {
#Autowired
private MyRepository myRepository;
I had a similar issue with Spring Data MongoDB: I had to add the package path to #EnableMongoRepositories
I resolved that issue by changing that dependency :
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
</dependency>
With that one :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
In that way there is no need to use Anotations like :
#EnableAutoConfiguration
#ComponentScan({"controller", "service"})
#EntityScan("entity")
#EnableJpaRepositories("repository")
)
I had a similar problem but with a different cause:
In my case the problem was that in the interface defining the repository
public interface ItemRepository extends Repository {..}
I was omitting the types of the template. Setting them right:
public interface ItemRepository extends Repository<Item,Long> {..}
did the trick.
In #ComponentScan("org.pharmacy"), you are declaring org.pharmacy package.
But your components in com.pharmacy package.
Many of the answer up there help a lot, because they are part of the whole solution. For me it was a mix of some of them.
Your ComponentScan package is wrong. Change it to:
#ComponentScan("com.pharmacy")
You also have to add:
#EnableJpaRepositories
to your SpringBootApplication class, here: SpringBootRunner.
I had to change the Maven dependency (works similarly for Gradle):
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
</dependency>
To:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Don't forget to refresh your dependencies.
Then I also had to change my imports in my Entity class to:
import jakarta.persistence.*;
Make sure the #Service or #Component that is trying to auto-wire the repository isn't in the same directory as your SpringApplication.class. Make sure it's in a subfolder like service/.
Sometimes I had the same issues when I forget to add Lombok annotation processor dependency to the maven configuration
Adding the below dependency on pom.xml solved the problem
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
If your main class is in com.example package your other class should which are in different packages should be called in com.example package;
i.e:Controller package
com.example.controller
AND
Your Main class should be in com.example not in com.example.main
if you gave the main class package as com.example.main then the other should be within that package e.g com.package.main.controller
