How to make instance of CrudRepository interface during testing in Spring?

Question

I have a Spring application and in it I do not use xml configuration, only Java Config. Everything is OK, but when I try to test it I faced problems wi

Answer 1

You cant use repositories in your configuration class because from configuration classes it finds all its repositories using @EnableJpaRepositories.

1. So change your Java Configuration to:

@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan("com.example")
@EnableJpaRepositories(basePackages={"com.example.jpa.repositories"})//Path of your CRUD repositories package
@PropertySource("classpath:application.properties")
public class JPAConfiguration {
  //Includes jpaProperties(), jpaVendorAdapter(), transactionManager(), entityManagerFactory(), localContainerEntityManagerFactoryBean()
  //and dataSource()  
}

2. If you have many repository implementation classes then create a separate class like below

@Service
public class RepositoryImpl {
   @Autowired
   private UserRepositoryImpl userService;
}

3. In your controller Autowire to RepositoryImpl and from there you can access all your repository implementation classes.

@Autowired
RepositoryImpl repository;

Usage:

repository.getUserService().findUserByUserName(userName);

Remove @Repository Annotation in ArticleRepository and ArticleServiceImpl should implement ArticleRepository not ArticleService.
