The primary goal of the https://spring.io/projects/spring-data[Spring Data] project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
The Spring Data MongoDB project aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities.
The Spring Data MongoDB project provides integration with the MongoDB document database.
Key functional areas of Spring Data MongoDB are a POJO centric model for interacting with a MongoDB +Document+
and easily writing a repository style data access layer.

[[getting-started]] == Getting Started
Here is a quick teaser of an application using Spring Data Repositories in Java:
[source,java]
public interface PersonRepository extends CrudRepository<Person, Long> {
List<Person> findByLastname(String lastname);
List<Person> findByFirstnameLike(String firstname); }
@Service public class MyService {
private final PersonRepository repository;
public MyService(PersonRepository repository) { this.repository = repository; }
public void doWork() {
repository.deleteAll();
Person person = new Person();
person.setFirstname("Oliver");
person.setLastname("Gierke");
repository.save(person);
List<Person> lastNameResults = repository.findByLastname("Gierke");
List<Person> firstNameResults = repository.findByFirstnameLike("Oli*");
} }
@Configuration @EnableMongoRepositories class ApplicationConfig extends AbstractMongoClientConfiguration {
@Override protected String getDatabaseName() { return "springdata"; } }
[[maven-configuration]] === Maven configuration
Add the Maven dependency:
[source,xml]
If you'd rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.
[source,xml]
[[upgrading]] == Upgrading
Instructions for how to upgrade from earlier versions of Spring Data are provided on the project https://github.com/spring-projects/spring-data-commons/wiki[wiki]. Follow the links in the https://github.com/spring-projects/spring-data-commons/wiki#release-notes[release notes section] to find the version that you want to upgrade to.
[[getting-help]] == Getting Help
Having trouble with Spring Data? We’d love to help!
- Check the https://docs.spring.io/spring-data/mongodb/reference/[reference documentation], and https://docs.spring.io/spring-data/mongodb/docs/current/api/[Javadocs]
- Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation. If you are just starting out with Spring, try one of the https://spring.io/guides[guides].
- If you are upgrading, check out the https://docs.spring.io/spring-data/mongodb/docs/current/changelog.txt[changelog] for "
new and noteworthy
" features. - Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data[
spring-data-mongodb
]. You can also chat with the community on https://gitter.im/spring-projects/spring-data[Gitter]. - Report bugs with Spring Data MongoDB at https://github.com/spring-projects/spring-data-mongodb/issues[github.com/spring-projects/spring-data-mongodb/issues].
[[reporting-issues]] == Reporting Issues
Spring Data uses Github as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:
- Before you log a bug, please search the https://github.com/spring-projects/spring-data-mongodb/issues[issue tracker] to see if someone has already reported the problem.
- If the issue does not already exist, https://github.com/spring-projects/spring-data-mongodb/issues/new[create a new issue].
- Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using, the JVM version, Stacktrace, etc.
- If you need to paste code, or include a stack trace use https://guides.github.com/features/mastering-markdown/[Markdown] code fences +++```+++.
[[guides]] == Guides
The https://spring.io/[spring.io] site contains several guides that show how to use Spring Data step-by-step:
- https://spring.io/guides/gs/accessing-data-mongodb/[Accessing Data with MongoDB] is a very basic guide that shows you how to create a simple application and how to access data using repositories.
- https://spring.io/guides/gs/accessing-mongodb-data-rest/[Accessing MongoDB Data with REST] is a guide to creating a REST web service exposing data stored in MongoDB through repositories.
[[examples]] == Examples
- https://github.com/spring-projects/spring-data-examples/[Spring Data Examples] contains example projects that explain specific features in more detail.
[[building-from-source]] == Building from Source
You do not need to build from source to use Spring Data. Binaries are available in https://repo.spring.io[repo.spring.io] and accessible from Maven using the Maven configuration noted <<maven-configuration,above>>.
NOTE: Configuration for Gradle is similar to Maven.
The best way to get started is by creating a Spring Boot project using MongoDB on https://start.spring.io[start.spring.io]. Follow this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb[link] to build an imperative application and this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb-reactive[link] to build a reactive one.
However, if you want to try out the latest and greatest, Spring Data MongoDB can be easily built with the https://github.com/takari/maven-wrapper[Maven wrapper] and minimally, JDK 17 (https://www.oracle.com/java/technologies/downloads/[JDK downloads]).
In order to build Spring Data MongoDB, you will need to https://www.mongodb.com/try/download/community[download] and https://docs.mongodb.com/manual/installation/[install a MongoDB distribution].
Once you have installed MongoDB, you need to start a MongoDB server. It is convenient to set an environment variable to
your MongoDB installation directory (e.g. MONGODB_HOME
).
To run the full test suite, a https://docs.mongodb.com/manual/tutorial/deploy-replica-set/[MongoDB Replica Set] is required.
To run the MongoDB server enter the following command from a command-line:
[source,bash]
$ $MONGODB_HOME/bin/mongod --dbpath $MONGODB_HOME/runtime/data --ipv6 --port 27017 --replSet rs0 ... "msg":"Successfully connected to host"
Once the MongoDB server starts up, you should see the message (msg
), "Successfully connected to host".
Notice the --dbpath
option to the mongod
command. You can set this to anything you like, but in this case, we set
the absolute path to a sub-directory (runtime/data/
) under the MongoDB installation directory (in $MONGODB_HOME
).
You need to initialize the MongoDB replica set only once on the first time the MongoDB server is started. To initialize the replica set, start a mongo client:
[source,bash]
$ $MONGODB_HOME/bin/mongo MongoDB server version: 6.0.0 ...
Then enter the following command:
[source,bash]
mongo> rs.initiate({ _id: 'rs0', members: [ { _id: 0, host: '127.0.0.1:27017' } ] })
Finally, on UNIX-based system (for example, Linux or Mac OS X) you may need to adjust the ulimit
.
In case you need to, you can adjust the ulimit
with the following command (32768 is just a recommendation):
[source,bash]
$ ulimit -n 32768
You can use ulimit -a
again to verify the ulimit
for "open files" was set appropriately.
Now you are ready to build Spring Data MongoDB. Simply enter the following mvnw
(Maven Wrapper) command:
[source,bash]
$ ./mvnw clean install
If you want to build with the regular mvn
command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.8.0 or above].
Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular, please sign the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change.
=== Building reference documentation
Building the documentation builds also the project without running tests.
[source,bash]
$ ./mvnw clean install -Pantora
The generated documentation is available from target/antora/site/index.html
