Spring boot application throwing exception while connecting to mongodb atlas

I'm trying to connect spring boot application with a mongodb cluster and I'm facing the following issue while starting the spring boot application.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoDatabaseFactory' defined in class path resource [org/springframework/boot/autoconfigure/data/mongo/MongoDatabaseFactoryConfiguration.class]: Failed to instantiate [org.springframework.data.mongodb.core.MongoDatabaseFactorySupport]: Factory method 'mongoDatabaseFactory' threw exception with message: Database name must not be empty

this is the application .properties file

I had the same issue. Add this for workaround:

@Configuration
public class MongoConfig extends AbstractMongoClientConfiguration {

@Autowired
Environment env;

@Override
protected String getDatabaseName() {
    return env.getProperty("spring.data.mongodb.database", "test");
}

@Override
public MongoClient mongoClient() {
    String uri = env.getProperty("spring.data.mongodb.uri", "mongodb://localhost/test");
    ConnectionString connectionString = new ConnectionString(uri);
    MongoClientSettings mongoClientSettings = MongoClientSettings.builder()
        .applyConnectionString(connectionString)
        .build();
    
    return MongoClients.create(mongoClientSettings);
}

}
