Question

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  org

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

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.

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

SpringBootApplication scanBasePackages   lt youur package name gt    EnableJpaRepositories  lt you jpa repo package gt    EntityScan  lt your entity package gt    Entity class like below   Entity  Table name  USER   public class User         Id      GeneratedValue

In SpringBoot  the JpaRepository are not auto-enabled by default  You have to explicitly add   EnableJpaRepositories  packages    EntityScan  packages

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  amp  Entities into another package and added the following to SpringApplication class    EnableJpaRepositories  com   jpa    EntityScan  com   jpa     After that  I moved the Service  interface  amp  implementation  to another package and added the following to SpringApplication class    ComponentScan  com   service     This solved my issues

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

User · Answer

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

User · Answer

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    lt base package name gt      EnableJpaRepositories basePackages   lt repository package name gt     EnableTransactionManagement  EntityScan basePackages   lt entity package name gt      Also  make sure you have the  Component annotations in place on the implementations

Sometimes I had the same issues when I forget to add Lombok annotation processor dependency to the maven configuration

User · Answer

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

User · Answer

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

User · Answer

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

In  ComponentScan  org pharmacy    you are declaring org pharmacy package  But your components in com pharmacy package

User · Answer

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 lt Item Long gt         did the trick

User · Answer

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

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

User · Answer

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
