This repository contains example projects for the different Spring Data modules to showcase the API and how to use the features provided by the modules.
We have separate folders for the samples of individual modules:
== Spring Data for Apache Cassandra
example - Shows core Spring Data support for Apache Cassandra.kotlin - Example for using Cassandra with Kotlin.reactive - Example project to show reactive template and repository support.== Spring Data Elasticsearch
example - Example how to use basic text search, geo-spatial search and facets. It uses
the High Level REST Client backing template and repository.reactive - Example how to use reactive client, template and repository features.Local Elasticsearch instance must be running to run the tests.
== Spring Data JDBC
basic - Basic usage of Spring Data JDBC.graalvm-native - This example compiles a basic Spring Data JDBC application into a GraalVM native image.howto - A collection of projects to go with the https://spring.io/blog/2021/09/09/spring-data-jdbc-how-to-use-custom-id-generation[Spring Data JDBC - How to blog posts].immutables - Showing Spring Data JDBC usage
with https://immutables.github.io/[Immutables]jmolecules - Demonstrates the interaction of jMolecules with Spring Data JDBC.jooq - Demonstrates how to use jOOQ and Spring Data JDBC together.mybatis - Demonstrate how to use MyBatis to generate SQL for Spring Data JDBC.singlequeryloading - Demonstrates how to enable Single Query Loading.== Spring Data JPA
eclipselink - Sample project to show how to use Spring Data JPA with Spring Boot and https://www.eclipse.org/eclipselink/[Eclipselink].example - Probably the project you want to have a look at first.
Contains a variety of sample packages, showcasing the different levels at which you can use Spring Data JPA.
Have a look at the simple package for the most basic setup.
Contains also examples running on Virtual Threads.interceptors - Example of how to enrich the repositories with AOP.jpa21 - Shows support for JPA 2.1 specific features (stored procedures support).multiple-datasources - Examples of how to use Spring Data JPA with multiple DataSources.query-by-example - Example project showing usage of Query by Example with Spring Data JPA.security - Example of how to integrate Spring Data JPA Repositories with Spring Security.showcase - Refactoring show case of how to improve a plain-JPA-based persistence layer by using Spring Data JPA (read: removing close to all of the implementation code).Follow the demo.txt file for detailed instructions.vavr - Shows the support of https://www.vavr.io[Vavr] collection types as return types for query methods.== Spring Data LDAP
example - Sample for Spring Data repositories to access an LDAP store.== Spring Data MongoDB
aggregation - Example project to showcase the MongoDB aggregation framework support.example - Example project for general repository functionality (including geo-spatial functionality), Querydsl integration and advanced topics.fluent-api - Example project to show the new fluent API (MongoTemplate-alternative) to interact with MongoDB.geo-json - Example project showing usage of http://geojson.org[GeoJSON] with MongoDB.gridfs - Example project showing usage of gridFS with MongoDB.jmolecules - Example of Spring Data MongoDB working with a jMolecules based domain model.kotlin - Example for using https://kotlinlang.org/[Kotlin] with MongoDB.linking - Example demonstrating possibilities for linking documents.query-by-example - Example project showing usage of Query by Example with MongoDB.querydsl - Example project showing imperative and reactive https://github.com/querydsl/querydsl[Querydsl] support for MongoDB.reactive - Example project to show reactive template and repository support.repository-metrics - Example project to show how to collect repository method invocation metrics.security - Example project showing usage of Spring Security with MongoDB.text-search - Example project showing usage of MongoDB text search feature.transactions - Example project for imperative and reactive MongoDB 4.0 transaction support.== Spring Data Neo4j
example - Example to show basic node and relationship entities and repository usage.== Spring Data R2DBC
example - Basic usage of Spring Data R2DBC.== Spring Data Redis
cluster - Example for Redis Cluster support.example - Example for basic Spring Data Redis setup.pubsub - Example project to show Pub/Sub usage using Platform and Virtual Threads.reactive - Example project to show reactive template support.repositories - Example demonstrating Spring Data repository abstraction on top of Redis.sentinel - Example for Redis Sentinel support.streams - Example for https://redis.io/topics/streams-intro[Redis Streams] support.Local Redis instances must be running to run the tests. One option is to use Docker in a separate terminal:
$ docker run -p 6379:6379 redis:5.0WARNING: If you're done using it, don't forget to shut it down!
== Spring Data REST
headers - A sample showing the population of HTTP headers and the usage of them to perform conditional GET requests.multi-store - A sample REST web-service based on both Spring Data JPA and Spring Data MongoDB.projections - A sample REST web-service showing how to use projections.security - A sample REST web-service secured using Spring Security.starbucks - A sample REST web-service built with Spring Data REST and MongoDB.uri-customizations - Example project to show URI customization capabilities.== Spring Data web support
projections - Example for Spring Data web support for JSONPath and XPath expressions on projection interfaces.querydsl - Example for Spring Data Querydsl web integration (creating a Predicate from web requests).web - Example for Spring Data web integration (binding Pageable instances to Spring MVC controller methods, using interfaces to bind Spring MVC request payloads).== Miscellaneous
bom - Example project how to use the Spring Data release train bom in non-Spring-Boot
scenarios.map - Example project to show how to use Map-backed repositories.multi-store - Example project to use both Spring Data MongoDB and Spring Data JPA in
one project.== Note
