This article shows how to integrate MongoDB into your Spring project through annotation configuration.

We will begin with our Gradle configuration.

group 'com.gkatzioura.spring'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
    dependencies {

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'mdb-spring-boot'
    version =  '0.1.0'

repositories {

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {





task wrapper(type: Wrapper) {
    gradleVersion = '2.3'

We will proceed with the MongoDB configuration using spring annotations.

package com.gkatzioura.spring.config;

import com.mongodb.MongoClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.MongoDbFactory;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.SimpleMongoDbFactory;

import java.net.UnknownHostException;

 * Created by oSeven3 on 21/10/2015.
public class MongoDbConfiguration {

    public @Bean MongoDbFactory getMongoDbFactory() throws UnknownHostException {
        return new SimpleMongoDbFactory(new MongoClient("localhost",27017),"mongotest");

    public @Bean(name = "mongoTemplate") MongoTemplate getMongoTemplate() throws UnknownHostException {

        MongoTemplate mongoTemplate = new MongoTemplate(getMongoDbFactory());
        return mongoTemplate;


Next we will define our model. We shall create the Location model which will contain the latitude longitude.

package com.gkatzioura.spring.persistence.entities;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

import java.math.BigDecimal;
import java.util.Date;
import java.util.UUID;

@Document(collection = "location")
public class Location {

    private String id;
    private BigDecimal latitude;
    private BigDecimal longitude;
    private Date timestamp;

    public String getId() {
        return id;

    public void setId(String id) {
        this.id = id;

    public BigDecimal getLatitude() {
        return latitude;

    public void setLatitude(BigDecimal latitude) {
        this.latitude = latitude;

    public BigDecimal getLongitude() {
        return longitude;

    public void setLongitude(BigDecimal longitude) {
        this.longitude = longitude;

    public Date getTimestamp() {
        return timestamp;

    public void setTimestamp(Date timestamp) {
        this.timestamp = timestamp;

Then we shall create our repository:

package com.gkatzioura.spring.persistence.repositories;

import com.gkatzioura.spring.persistence.entities.Location;
import org.springframework.data.repository.CrudRepository;

import java.util.UUID;

public interface LocationRepository extends CrudRepository<Location,String> {

Then we shall define our controller:

package com.gkatzioura.spring.controller;

import com.gkatzioura.spring.persistence.entities.Location;
import com.gkatzioura.spring.persistence.repositories.LocationRepository;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.ArrayList;
import java.util.List;

import java.io.IOException;

 * Created by oSeven3 on 21/10/2015.

public class LocationController {

    private LocationRepository locationRepository;

    private static final Logger LOGGER = LoggerFactory.getLogger(LocationRepository.class);

    @RequestMapping(value = "/",method = RequestMethod.POST)
    public String post(@RequestBody Location location) {


        return "OK";

    @RequestMapping(value = "/",method = RequestMethod.GET)
    public List<Location> get() {

        List<Location> locations = new ArrayList<>();
        return locations;


Last but not least our Application class:

package com.gkatzioura.spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

 * Created by gkatziourasemmanouil on 8/15/15.
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);


In order to run just run:

gradle bootRun
