Spring-boot: Spring boot 2.0.0RC1 with data mongo: Couldn't find PersistentEntity for type class

[N-Andronopoulos]

When I use this class configuration, I cannot persists an Object (MyObj) with this repository:

public interface MyObjRepository extends MongoRepository<MyObj, String> { ... }

@Configuration
@EnableMongoAuditing
@EnableMongoRepositories(basePackages = {"mypackage.backendapi.repositories"})
@Profile("testing")
@PropertySource("classpath:/mongo.dev.properties")
public class DevMongoConfig extends AbstractMongoConfiguration {
   ....
}

But it works when I use this with mongo config in application.properties:
```
@EnableMongoAuditing
@SpringBootApplication
public class BackendApiApplication { ... }

The error that im getting is:

java.lang.IllegalArgumentException: Couldn't find PersistentEntity for type class mypackage.backendapi.models.MyObj!

Extending AbstractMongoConfiguration will switch off Spring Boot's auto-configuration of various Mongo components and also customises the base packages that are used to scan for mappings. I would recommend that you don't use it in Spring Boot.

[N-Andronopoulos]

That did the trick.
Thank you very much!

[dhanaraj1]

@wilkinsona
have you found anything on this isuue ?
I am facing same issue.

[wilkinsona]

@dhanaraj1 See my comment above.

[carlislefox]

I also experienced this issue, however it was Spring Data Rest that was unhappy. Rather than not extending AbstractMongoConfiguration as suggested here, I found it was due to not having the mappingBasePackages specified:

    @Override
    protected Collection<String> getMappingBasePackages() {
        return Stream.of("uk.co.whatever.domain").collect(Collectors.toList());
    }

For some reason Spring Data was able to find the domain entities by itself, however Spring Data Rest was not and was relying on this method to point it in the right place.

_Edit: To be clear, the above method is an override point in AbstractMongoConfiguration_

[Bhagwati]

@carlislefox Thanks for your help. I was able to fix it using your solution.
If we don't override by default it would consider domain class package for domain.

MongoConfigurationSupport

/**
     * Returns the base packages to scan for MongoDB mapped entities at startup. Will return the package name of the
     * configuration class' (the concrete class, not this one here) by default. So if you have a
     * {@code com.acme.AppConfig} extending {@link MongoConfigurationSupport} the base package will be considered
