Spring - Multiple Spring Data modules found, entering strict repository configuration mode

Question

I am using Spring boot 2 with Spring Data, Spring-Data-Elastisearch and Spring-data-Redis(for http sessions). When i start the app. I'm receiving

2017-10-29 17:38:33.376  INFO 18625 --- [  restartedMain] .s.d.r.c.RepositoryConfigurationDelegate : Multiple Spring Data modules found, entering strict repository configuration mode!

In my App.java file, i have the following lines (which should avoid the ambiguity)

@EnableJpaRepositories(basePackages = {"com.ecommerce.core.repository.jpa"})
@EnableElasticsearchRepositories(basePackages= {"com.ecommerce.core.repository.elastic"})
@EnableRedisRepositories(basePackages = {"org.springframework.data.redis.connection.jedis"})

Every spring data repository extends specific for his job Interface (mainly JpaRepository and one of ElasticsearchCrudRepository

I read this -https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.multiple-modules.types and as you can see, everything should work without issues.

Answer 1

Your configurations are all right. The problem is caused by RedisRepositoriesAutoConfiguration. It registers EnableRedisRepositories repeatedly only with default config, which with empty basePackages.

To solve the problem, you could exclude RedisRepositoriesAutoConfiguration by:

@SpringBootApplication(
        exclude = { RedisRepositoriesAutoConfiguration.class }
)
public class MySpringBootApp {

}
