i'm using spring boot 2.2.5.RELEASE and spring-data-2.2.5.RELEASE

we have multiple projects in different git repositories and I'm trying to create a common JSON repository to work with MySQL JSON functions via shared jar.

i created the following in my common jar which has an autoconfiguration

@NoRepositoryBean
public interface JsonRepository <T>{

    int appendToArray(T entity, String arrayPath, Object item, String storeId) throws JsonProcessingException;

    int removeFromArrayByValue(T entity, String arrayPath, String feild, String value, String storeId);
}

configuration class

@EnableJpaRepositories(repositoryBaseClass = JsonRepositoryImpl.class,
        repositoryFactoryBeanClass = JsonRepositoryFactoryBean.class
)
@Configuration
public class RepositoryConfig {

}

and i have a spring.factorie files in my resources which configures this as autoconfiguration

and my implementation repository

@Repository
public interface SettingsRepository extends JsonRepository<Settings>, CrudRepository<Settings, Long> {
}

the problem

when i consume my common jar which include all json commons i made, spring-data stopes detecting all repositories and i can't start the application because of missing beans

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'XXXService' defined in file [XXXService.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.xxx.XXXRepository' available: expected at least 1 bean which qualifies as autowire candidate.

    at org.springframework.beans.factory.support.ConstructorResolver.resolveAutowiredArgument(ConstructorResolver.java:885)
    at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:789)

it only works if i add another @configuration in the consuming project, and i want to make it work automatically to save defining it on every project i want to add JSON query capabilities

@EnableJpaRepositories(
        repositoryBaseClass = JsonRepositoryImpl.class,
        repositoryFactoryBeanClass = JsonRepositoryFactoryBean.class,
        basePackages = "xxx.*"
)
public class CoreConfig {
}

how i can fix it ??

  • Try to make `JsonRepository ` extend `org.springframework.data.jpa.repository.JpaRepository` in order to make Spring implicitly autogenerate implementation for it. – Nikolai Shevchenko Jan 20 '21 at 14:17
  • i don't need an implementation for JsonRepository, is it just a composite interface – Elia Rohana Jan 20 '21 at 14:21
  • Then you loose SpringData "magic" that generates repository implementation. Error message clearly states it: `No qualifying bean of type 'com.xxx.XXXRepository'` – Nikolai Shevchenko Jan 21 '21 at 07:36
  • i want spring to generate an implementation for a repository that extends JsonRepository, and not for JsonRepository itself, for example SettingsRepository. – Elia Rohana Jan 21 '21 at 13:25
