How to disable spring-data-mongodb in spring-boot

I am new to SpringBoot. I have built a simple application which should use fake data in the development environment, and connect to MongoDb in the test environment. Dev environment does not have mongodb setup.

I have tried using Spring Boot qualifiers/profiles to achieve it.

I have a main class which looks like the following:

@SpringBootApplication public class Main { public static void main(String[] args) { SpringApplication.run(Main.class, args); } } 

I have a DAO interface StudentDao.java

public interface StudentDao { Student getStudentById(String id); } 

I then created a couple of implementations for the DAO, one for fake data, and one for data from Mongo

FakeStudentDaoImpl.java

@Repository @Qualifier("fakeData") public class FakeStudentDaoImpl implements StudentDao { private static Map<String, Student> students; static { students = new HashMap<String, Student>(){ { put("1", new Student("Ram", "Computer Science")); } }; } @Override public Student getStudentById(String id){ return this.students.get(id); } } 

MongoStudentDaoImpl.java

@Repository @Qualifier("mongoData") public class MongoStudentDaoImpl implements StudentDao { @Autowired private MongoStudentRepo repo; @Override public Student getStudentById(String id) { return repo.findById(id).get(); } } 

The MongoStudentRepo is a simple interface extending MongoRepository:

public interface MongoStudentRepo extends MongoRepository<Student, String> { } 

And my POM file has the following dependencies called out:

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId> </dependency> 

Of course, I have other controller classes. This works fine in the Test environment, where there is a MongoDb, and it is able to connect to it. However, when I am trying to start it in my local environment, it fails to start because it is not finding MongoDb on startup.

How do I disable the MongoDb part in my local environment (and just use fake data)? I want to make the same code work in both environments.

Thanks in advance.
