Embedded MongoDB with Spring not working

I am trying to create a Spring application with WebFlux and an embedded MongoDB. However, even if my tests runs perfectly, I can't start my application because it seems that embedded mongodb has not started.

The exception that I get is the following:

My application properties is just a blank file. My repository class is the following:

import com.lorescianatico.driftcoin.model.BlockChain;
import org.springframework.data.mongodb.repository.ReactiveMongoRepository;

public interface BlockChainRepository extends ReactiveMongoRepository<BlockChain, String> {
}

As you can see, I am using reactive repository for mongodb. I already tried to activate via annotations reactive repositories but it didn't change the exception. Am I missing something, like a configuration or similar?

Thanks in advance.

Posting my solution, as it may help someone - I've added version tode.flapdoodle.embed.mongo dependency and it did a trick:

Use this:

        <dependency>
            <groupId>de.flapdoodle.embed</groupId>
            <artifactId>de.flapdoodle.embed.mongo</artifactId>
            <version>2.2.0</version>
            <scope>test</scope>
        </dependency>

instead of this:

        <dependency>
            <groupId>de.flapdoodle.embed</groupId>
            <artifactId>de.flapdoodle.embed.mongo</artifactId>
            <scope>test</scope>
        </dependency>

I solved the problem by installing mongo on the VM and then running the Spring boot instance.

For me the embedded mongo driver (de.flapdoodle.embed.mongo) was not working, so I removed the dependancy.

  1. Install Mongo & run it

    • sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
    • echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
    • sudo apt-get update
    • sudo apt-get install -y mongodb-org
    • sudo service mongod restart

  2. Run Spring Boot Application

Your embedded mongodb is set to be used when you are testing:

<dependency>
    <groupId>de.flapdoodle.embed</groupId>
    <artifactId>de.flapdoodle.embed.mongo</artifactId>
    <scope>test</scope>
</dependency>

Remove the test scope from there so you can use it at runtime:

<dependency>
    <groupId>de.flapdoodle.embed</groupId>
    <artifactId>de.flapdoodle.embed.mongo</artifactId>
</dependency>

When using grade I got the same problem and the issue was with my build.gradle solved it by changing this line:

testCompile('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

to

compile('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

So issue has to be in your pom the embedded mongodb is not being setup.

have you added these mongo properties in your application.properites

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=app1

spring boot mongo example
