Conflict between Spring data MongoDb and Elasticsearch

Question

I started a project in which I use both Mongo, Elasticsearch and spring boot.

With either technologies by itself, the project works just fine. However with both together, they conflict. I saw this particular article that seemed to be similar to my issue. https://jira.spring.io/browse/DATAES-57 So I tried it out and it the problem is still there.

I put these on the Main class

@EnableAutoConfiguration(exclude = MongoRepositoriesAutoConfiguration.class)
@EnableMongoRepositories(basePackages = "com.searchizi.mongo.repository")
@EnableElasticsearchRepositories(basePackages = "com.searchizi.elasticsearch.repository")
@ComponentScan
public class Application implements CommandLineRunner { … }

A shortened form the the exception trace is this

The class SearchiziUser is in the com.searchizi.mongo.model package. It is not on the Elasticsearch scan path.

Caused by: java.lang.IllegalArgumentException: Unable to identify index name. SearchiziUser is not a Document. Make sure the document class is annotated with @Document(indexName="foo")

The scanning for each repository type should be separated but apparently it is not. Any idea what to do?

Answer 1

This is clearly a bug in Spring Data Elasticsearch as it seems to scan for domain types in packages it actually shouldn't. I filed DATAES-?? for you. Also, I filed a ticket so that Spring Data Elasticsearch supports the new multi-store configuration improvements so that you shouldn't have to explicitly configure separate packages.

On a side note, excluding the auto-configuration is not necessary if you set up @EnableMongoRepositories as it will automatically disable Spring Boot's auto-configuration.

I faced this exception and I resolved by change version of elasticsearch and mongodb lib versions
