spring boot '1.1.6' project. to '1.2.0.RC1' : Cannot subclass final class class com.sun.proxy.$Proxy88

[aasheikh]

I had the following code in spring boot '1.1.6' project. I have changed to '1.2.0.RC1'

It caused the error below. I have removed the @Repository stereotype and it has worked.
I haven't changed anything else in the project

@Repository
public interface ShowRoomReposiory extends MongoRepository<ShowRoom, ObjectId> {}

It would be nice if you attach the exact code that triggers this exception. First, there's a typo in the sample code above (it's not Repository). Then it's missing the generic type that defines the entity and primary key to use

When you define them on the most possible simple ShowRoom class it works just fine so something is more complicated with your setup.

[philwebb]

My guess is that the PersistenceExceptionTranslationAutoConfiguration which we added to 1.2 is causing that exception. You could try setting spring.dao.exceptiontranslation.enabled=false in your application.properties to disable it.

You actually don't need to use @Repository annotations with Spring Data's Repository interfaces, so perhaps the easiest fix is just to remove them.

[philwebb]

I think removing the @Repository annotation should be enough. Please reopen if you're still having issues.

[aasheikh]

Sorry! for not replying earlier.

Yes, removing the @repository works as I have mentioned in the issue.
if you are still interested in reproducting it , please find the following project. it is a modified 'spring-boot-sample-data-mongodb' project. Yes, I may not need it, but just wondering why it has worked in spring boot '1.1.6' and not in '1.2.0.RC1'

just run 'gradle test'

Thanks

I don't think removing the Repository annotation is a correct solution - what if you want to rename the bean. I normally use the value attribute on the Repository annotation.

[ptahchiev]

For me this issue happens because I have 2 interfaces:

public interface PointOfServiceSearchRepository<T extends SearchRequestPointOfServiceData> extends PagingAndSortingRepository<T, Long> {

   String NAME = "pointOfServiceSearchRepository";

   Page<T> findByCoordinatesNear(final Point point, final Distance distance, final Pageable pageable);

   T findByNameContains(String name);
}

and then inside another module I have Solr implementation (another interface that extends this interface):

@Repository(value = PointOfServiceSearchRepository.NAME)
@RepositoryRestResource(exported = false)
public interface DefaultSolrsearchPointOfServiceRepository extends SolrRepository<SolrsearchRequestPointOfServiceData, Long>, PointOfServiceSearchRepository<SolrsearchRequestPointOfServiceData> {

   @Query(value = "en_name:?0")
   SolrsearchRequestPointOfServiceData findByNameContains(final String name);

}

when I remove the @repository annotation I cannot autowire the repository:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.nemesis.platform.module.search.core.repository.PointOfServiceSearch
Repository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.facto

Have you tried setting spring.dao.exceptiontranslation.enabled=false in your application.properties? Alternatively you could use the @Component annotation if you need to rename the bean.

[emersonf]

I had the same problem going from 1.1.9 to 1.2.1. In my case both solutions work, i.e. disabling the exception translator or removing the @Repository annotations.

[aisven]

I do not like the suggested solutions.

• It is cumbersome to add the property to all application property files if you have many microservices and several target environments.
• It is also not nice to be forced to remove the @Repository stereotype. Especially where you already have a lot of repositories and large distributed dev teams producing new microservices choosing the Spring Boot way, it is again cumbersome.

How about forking this issue to the Spring Data umbrella project and its sub projects to make it work (if this has not been done already)? @olivergierke
