I am new and I try to develop an API with Java Spring Boot.
I have a problem with MongoDB Config and I have no problem in another project. I don't understand why.
I have already looked but the solutions proposed do not work.

SBApplication.java :

package basket;



import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.autoconfigure.data.mongo.MongoRepositoriesAutoConfiguration;

import org.springframework.boot.autoconfigure.domain.EntityScan;

import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration;



import springfox.documentation.swagger2.annotations.EnableSwagger2;



@SpringBootApplication (scanBasePackages = { "basket.instrastructure.dao" })

@EnableSwagger2

@EnableAutoConfiguration //(exclude={MongoAutoConfiguration.class, MongoRepositoriesAutoConfiguration.class})

public class SBApplication {



    public static void main(String args) {

        SpringApplication.run(SBApplication.class, args);

    }

}

BasketRepository.java :

package basket.infrastructure.dao;



import java.util.ArrayList;



import org.springframework.data.mongodb.repository.MongoRepository;

import org.springframework.stereotype.Repository;



import basket.domaine.model.Basket;



@Repository 

public interface BasketRepository extends MongoRepository<Basket, Long> {



    public ArrayList<Basket> findAll();

    public Basket findById(String id);    

}

ItemRepository.java :

package basket.infrastructure.dao;



import java.util.ArrayList;



import org.springframework.data.mongodb.repository.MongoRepository;

import org.springframework.stereotype.Repository;



import basket.domaine.model.Item;





@Repository

public interface ItemRepository extends MongoRepository<Item, Long> {

    public Item findByName(String name);

    public ArrayList<Item> findAll();

    public Item findById(String id);

}

MongoConfig.java :

package basket.application.components;



import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.data.mongodb.config.AbstractMongoConfiguration;

import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;



import com.mongodb.Mongo;

import com.mongodb.MongoClient;

import com.mongodb.MongoClientURI;

import com.mongodb.client.MongoDatabase;



@Configuration

@EnableMongoRepositories ("basket.infrastructure.dao")

public class MongoConfig extends  AbstractMongoConfiguration {



    @Override

    @Bean

    public Mongo mongo() throws Exception {

        MongoClientURI uri = new MongoClientURI("mongodb+srv://owner:AAAAA@basketcluster-feebu.mongodb.net/test?retryWrites=true");

        MongoClient mongoClient = new MongoClient(uri);

        MongoDatabase database = mongoClient.getDatabase("test");

        return mongoClient;

    }



    @Override

    protected String getDatabaseName() {

        return "test";

    }

}

And I have this error

Can you help me to understand my mistake.
Thank you, any help is very much appreciated!

Are you sure about your MongoDB URI? Usually, the URI has the form mongodb://localhost:27017/foo.

If you use Spring-boot instead of using a Configuration bean I suggest you use application.properties file. In this file write a property likes spring.data.mongodb.uri=mongodb://localhost:27017/foo and Spring-boot automatically injects the properties in MongoClient without any configuration at the code level.
