How do I fix "Could not autowire. No beans of 'MyRepository' type found"?

February 15, 2022

I have this hierarchy in my project:

▼ server
  ▼ myproject
    ▼ src
      ▼ main
        ▼ java
          ▼ rest
            ▼ repository
              Ⓘ MyRepository
        ▶ resources
      ▼ test
        ▼ java
          ▼ rest
            Ⓒ MyRepositoryTest

This is the MyRepository interface:

public interface MyRepository extends MongoRepository<String, Integer> {
}

This is the MyRepositoryTest test class:

@ExtendWith(SpringExtension.class)
public class AdminEvaluatorTest {
    ...
    @Autowired MyRepository myRepository;
    ...
}

The error occurs on the autowired myRepository instance in the test class. It says Could not autowire. No beans of 'MyRepository' type found. I’ve searched a bit and tried to add @Component, @Repository and so on, but nothing really helps. How do I fix this issue?

>Solution :

You could try this, set your package in @ComponentScan of the class AppConfig:

@ContextConfiguration(classes = AppConfig.class)
@ExtendWith(SpringExtension.class)
public class AdminEvaluatorTest {
    @Autowired MyRepository myRepository;

    @Configuration
    @ComponentScan("com.<your-package>")
    public static class AppConfig {
    }
}
