Java Spring Boot MongoDB Configuration

Question

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:[email protected]/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

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.

I will test with the application.porperties file I had a project in which I had no problem but I redid with DDD architecture. And now I have the problem. The database is on the server mongoDB. And in the doc I can connect to the data base with : MongoClientURI uri = new MongoClientURI( "mongodb+srv://kay:[email protected]/"); MongoClient mongoClient = new MongoClient(uri); MongoDatabase database = mongoClient.getDatabase("test");

Try as @Federico Gatti said by configuring Mongo iuth properties file:

spring.data.mongodb.database=MongoDatabaseName
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017

Use properties file to configure your database with application and let the spring boot do everything for you with db configuration.

Go to the resources/application.properties file, and add the following content to it:

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=mydatabase

That will allow your application to correctly connect to your MongoDB database.

Also, Go to the main application class, and add the following annotation before its declaration:

@EnableMongoRepositories(basePackageClasses = foo.class)
