[WARNING]

This project is about to move to the https://github.com/spring-attic/[Spring Attic] and is not recommended for new projects. + The last Release (4.3.0) will, as part of the spring data release 2020.0, see patch updates till mid 2022.

The primary goal of the https://projects.spring.io/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 for Apache Solr project provides integration with the https://lucene.apache.org/solr/[Apache Solr] search engine

Providing its own extensible MappingSolrConverter as alternative to DocumentObjectBinder Spring Data for Apache Solr handles inheritance as well as usage of custom Types such as Point or DateTime

== Features

• High level repository abstractions with multicore support
• Annotations for Boost-, Facet- and Highlighting
• Customizable type mappings and type conversions
• Solr template supporting fluent query api
• Exception translation to Spring’s portable Data Access exception hierarchy

== Code of Conduct

This project is governed by the https://github.com/spring-projects/.github/blob/e3cc2ff230d8f1dca06535aa6b5a4a23815861d4/CODE_OF_CONDUCT.md[Spring Code of Conduct]. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to [email protected].

== 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 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("Christoph");
person.setLastname("Strobl");
repository.save(person);

List<Person> lastNameResults = repository.findByLastname("Strobl");
List<Person> firstNameResults = repository.findByFirstnameLike("C*");

} }

@Configuration @EnableSolrRepositories(schemaCreationSupport = true) class Config {

@Bean public SolrClient solrClient() { return new HttpSolrClient("http://localhost:8983/solr"); } }

=== Maven configuration

Add the Maven dependency:

[source,xml]

org.springframework.data spring-data-solr ${version}.RELEASE ----

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-solr ${version}.BUILD-SNAPSHOT spring-libs-snapshot Spring Snapshot Repository https://repo.spring.io/libs-snapshot ----

== Getting Help

Having trouble with Spring Data? We’d love to help!

• Check the https://docs.spring.io/spring-data/solr/docs/current/reference/html/[reference documentation], and https://docs.spring.io/spring-data/solr/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/solr/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-solr`]. You can also chat with the community on https://gitter.im/spring-projects/spring-data[Gitter].
• Report bugs with Spring Data for Apache Solr at https://jira.spring.io/browse/DATASOLR[jira.spring.io/browse/DATASOLR].

== Reporting Issues

Spring Data uses JIRA 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://jira.spring.io/browse/DATASOLR[issue tracker] to see if someone has already reported the problem.
• If the issue doesn’t already exist, https://jira.spring.io/browse/DATASOLR[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 and JVM version.
• If you need to paste code, or include a stack trace use JIRA {code}…{code} escapes before and after your text.
• If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.

== Building from Source

You don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper]. You also need JDK 1.8.

[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 v3.5.0 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 -Pdistribute

The generated documentation is available from target/site/reference/html/index.html.
