The Spring Data 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. [[code-of-conduct]] == Code of Conduct This project is governed by the https://github.com/spring-projects/.github/blob/main/CODE_OF_CONDUCT.md[Spring Code of Conduct]. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to spring-code-of-conduct@spring.io. [[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 { List findByLastname(String lastname); List 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("Drotbohm"); repository.save(person); List lastNameResults = repository.findByLastname("Drotbohm"); List 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] ---- org.springframework.data spring-data-mongodb ${version} ---- 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] ---- org.springframework.data spring-data-mongodb ${version}-SNAPSHOT spring-snapshot Spring Snapshot Repository https://repo.spring.io/snapshot ---- [[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]. * Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data[`spring-data-mongodb`]. * 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. * Ideally provide a complete https://stackoverflow.com/help/minimal-reproducible-example[minimal sample] (something that we can unzip or git clone, build, and deploy) that reproduces the problem. * 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 <>. 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] and https://www.docker.com/products/docker-desktop/[Docker]. 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: 8.0.0 ... ---- 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] and add a _Signed-off-by_ trailer to your commits, if you wish to submit a pull request. === 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`.
