spring data mongodb host and spring data mongodb port are not supported if you   re using the Mongo 3 0 Java driver  In such cases  spring data mongodb uri should be used to provide all of the configuration  like this    spring data mongodb uri mongodb   user secret mongo1 example com 12345

It s also important to note that MongoDB has the concept of  authentication database   which can be different than the database you are connecting to  For example  if you use the official Docker image for Mongo and specify the environment variables  MONGO INITDB ROOT USERNAME and MONGO INITDB ROOT PASSWORD  a user will be created on  admin  database  which is probably not the database you want to use  In this case  you should specify parameters accordingly on your application properties file using    spring data mongodb host 127 0 0 1 spring data mongodb port 27017 spring data mongodb authentication-database admin spring data mongodb username  lt username specified on MONGO INITDB ROOT USERNAME gt  spring data mongodb password  lt password specified on MONGO INITDB ROOT PASSWORD gt  spring data mongodb database  lt the db you want to use gt

In a maven project create a file src main resources application yml with the following content   spring profiles  integration   use local or embedded mongodb at localhost 27017 --- spring profiles  production spring data mongodb uri  mongodb    lt user gt   lt passwd gt   lt host gt   lt port gt   lt dbname gt    Spring Boot will automatically use this file to configure your application  Then you can start your spring boot application either with the integration profile  and use your local MongoDB    java -jar -Dspring profiles active integration your-app jar   or with the production profile  and use your production MongoDB   java -jar -Dspring profiles active production your-app jar

Just to quote Boot Docs      You can set spring data mongodb uri property to change the url  or alternatively specify a host port  For example  you might declare the following in your application properties    spring data mongodb host mongoserver spring data mongodb port 27017   All available options for spring data mongodb prefix are fields of MongoProperties   private String host   private int port   DBPort PORT   private String uri    mongodb   localhost test    private String database   private String gridFsDatabase   private String username   private char   password

You can define more details by extending AbstractMongoConfiguration    Configuration  EnableMongoRepositories  demo mongo model   public class SpringMongoConfig extends AbstractMongoConfiguration        Value    spring profiles active        private String profileActive        Value    spring application name        private String proAppName        Value    spring data mongodb host        private String mongoHost        Value    spring data mongodb port        private String mongoPort        Value    spring data mongodb database        private String mongoDB        Override     public MongoMappingContext mongoMappingContext           throws ClassNotFoundException              TODO Auto-generated method stub         return super mongoMappingContext               Override      Bean     public Mongo mongo   throws Exception           return new MongoClient mongoHost         mongoPort              Override     protected String getDatabaseName                TODO Auto-generated method stub         return mongoDB
