I'm developing a spring boot application and I'm running into an issue here. I'm trying to inject a @Repository annotated interface and it doesn't seem to work at all. I'm getting this error

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?
                And what if you create another component and inject your 'UserEntityDao userEntityDao' to it? (also a sidenote: never inject dependencies directly to fields, use constructor with proper arguments and @Autowired/@Inject on it).

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
                Strange docs says "By default, Spring Boot will enable JPA repository support and look in the package (and its subpackages) where @SpringBootApplication is located." spring.io/guides/gs/accessing-data-jpa

                I had this same issue. Once I specified a package for my repositories, I received another error Entity is not a managed type. For anyone else having this issue, You also need to add the annotation @EntityScan("com.package.dtos")

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.
                This should be the answer actually as it resolved the complete issue. as It gives not mapped type error after just adding @EnableJpaRepositories

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.
                Good shout! Thanks. For me I was using a redis repo, so defining the redish hash fixed it. e.g. @RedisHash(LanguageMapping.KEY_NAME)

                This hint saved my day! Thanx a lot! I only had a wrong import so the typing of the repository was incompatible which led to the error message!

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.
                "Actually you do not need the component scan if you have your main class at the top of the structure" worked for me!

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")
                Same issue I was facing, I had Repo and Entity in a library project, which was added as a dependency in an application project. There in the App.java need to enable these explicitly.

                Thank you, I had same issue as @FrancisRaj and after adding both @EnableJpaRepositories and @EntityScan with full package path, I could use my library project to connect with database

@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 {
    @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{
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)
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.
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 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.
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>
<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.*;
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
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
