Mongo Http Configuration Class not found Error

Question

The project is based on PetClinic . The data connects from the HANA DB and it works fine(creating tables,insert data).When I do Maven Install I am getting the following error where I am not using MongoDB. How to exclude/resolve this this.

ProductionConfigurationTests:

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.samples.petclinic.vet.VetRepository;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@RunWith(SpringRunner.class)
@SpringBootTest
@ComponentScan({"org.springframework*"})
@EntityScan("com.springframework*")
@EnableJpaRepositories("com.springframework*")
public class ProductionConfigurationTests {

    @Autowired
    private VetRepository vets;

    @Test
    public void testFindAll() throws Exception {
        vets.findAll();
        vets.findAll(); // served from cache
    }
}

I tried downloading and added the spring-session-data.jar but it is still giving the same error. Kindly guide as I am new to this Maven/Spring

Thanks

Answer 1

Your test is causing the issue. You are trying to scan the Spring packages which contains a lot of Autoconfiguration and other Configuration classes which the context is trying to load. You should never do this.

All you should need to do for your test is this add

@RunWith(SpringRunner.class)
@SpringBootTest

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

You could also use a @DataJpaTest

The SpringBootTest will use your SpringBootApplication class which will component scan for you, it should be placed the root of your package structure, and it will scan the child packages for you.
