Can't Autowire @Repository annotated interface in Spring Boot

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{

}

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 {

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!

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.

I had a similar issue with Spring Data MongoDB: I had to add the package path to @EnableMongoRepositories

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.

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")

)

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
