What results can you expect

Some example scenarios are shown below:

Creation of database objects

With application.properties

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=hc4

logging.level.org.springframework.data=debug
logging.level.=error

With Java configuration file

package com.mkyong;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;

import com.mongodb.Mongo;
import com.mongodb.MongoClient;

@Configuration
@EnableMongoRepositories
public class ApplicationConfig extends AbstractMongoConfiguration{
     @Override
     @Bean
      protected String getDatabaseName() {
        return "e-store";
      }

      @Override
      protected String getMappingBasePackage() {
        return "com.oreilly.springdata.mongodb";
      }
    @Override
    @Bean
    public Mongo mongo() throws Exception {
        // TODO Auto-generated method stub
        return new Mongo("localhost");
    }
}

Insert Operation

public Product getMrepefOne () {
    Product product = new Product("LN1", "London", 5.0f);
    productRepository.save(product);

    return productRepository.findOne("LN1");
}

@Override
    public BulkWriteResult bulk(Collection<? extends T> objects) {
      Assert.notNull(objects, "Objects must not be null!");
      return mongoTemplate.bulkOps(bulkMode != null ? bulkMode : BulkMode.ORDERED, Product.class)
          .insert(new ArrayList<>(objects)).execute();
    }

Update Operation

public String updateAlertStatus(String alertId) {

        LOGGER.debug("FanAlertsRepository.deleteAlert() with param{0}" + alertId);
        Query query = new Query();

        query.addCriteria(Criteria.where(AlertServiceConstants._ID_FILED).is(new ObjectId(alertId)));

        FanAlerts fanAlert = mongoOperation.findOne(query, FanAlerts.class,
                AlertServiceConstants.FAN_ALERTS_COLLECTION);
        if (fanAlert == null) {
            return AlertServiceConstants.failure;

Delete Operation

public Response deleteTn(String siteId, String tn) {
        DeleteResult deleteres = mongoCon.getCollection()
                    .deleteOne(new Document().append(DETAILSSITE_IDEN, siteId).append(DETAILS_TN, tn));
}

Select Operation

public GeoResults getProductByLocation (double longitude,double latitude,double distance){
    Point p = new Point(longitude, latitude);
    NearQuery nearQuery  = NearQuery.near(p, Metrics.KILOMETERS).maxDistance(distance);
    return mongoTemplate.geoNear(nearQuery, Product.class);
    
}

Query Methods

@Query("{ 'age' : { $gt: ?0, $lt: ?1 } }")
    List<User> findUsersByAgeBetween(int ageGT, int ageLT);

Known Limitations

Resolution of Database and Collection is limited, “Unknown” is used when not resolved.
Query method results in link between query method and repository collection (domain entity) and not between the actual caller method and repository collection
