Changes to mongo collection not visible across sessions - mongodb

Question

this is my mongo config:
#Configuration
public class MongoConfig {
#Bean
public MongoCustomConversions customConversions() {
return new MongoCustomConversions(Arrays.asList(new OffsetDateTimeReadConverter(), new OffsetDateTimeWriteConverter()));
}
#Bean
public ValidatingMongoEventListener validatingMongoEventListener() {
return new ValidatingMongoEventListener(validator());
}
#Bean
public LocalValidatorFactoryBean validator() {
return new LocalValidatorFactoryBean();
}
}
and:
spring:
data:
mongodb:
uri: mongodb://localhost:27017/my-database
I have noticed that whatever changes I am making to my collection in the Spring Boot service, whether I use repository or MongoOperations, save or find, they are visible only during the lifetime of the Spring Boot service and are NOT visible with command line mongo interface. Also the documents that I add with mongo command line are NOT visible to the spring boot service.
To my knowledge I have only one instance of mongodb, only one is visible in Task manager. I double checked the name of db and collection, too.
What could be the reason?

Answer 1

I have found that the problem was caused by embedded MongoDB:
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
Despite the scope being test, the embedded server run also for the main configuration. I could observe this behaviour only in eclipse, not in Intellij.
I could solve or at least circumvent the problem by excluding the embedded configuration:
#SpringBootApplication(exclude = EmbeddedMongoAutoConfiguration.class)
public class MyApplication
