In this post, we'll take a look at how to use Spring Boot with Apache Solr. We'll cover the following topics:
Apache Solr is a powerful open source search platform built on top of Apache Lucene. It provides a robust and scalable search solution for websites and applications.
Spring Boot is a popular Java framework for building web applications. It makes it easy to create stand-alone, production-grade Spring-based applications that you can "just run."
Apache Solr is a great fit for Spring Boot applications because it is easy to set up and configure. Spring Boot also provides first-class support for Solr via the Spring Data Solr project.
Using Apache Solr with Spring Boot is easy. In this section, we'll walk through the steps necessary to set up and use Apache Solr with a Spring Boot application.
First, we need to add the Spring Boot Starter dependency for Solr to our pom.xml
file:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-solr</artifactId>
</dependency>
Next, we need to configure the Solr server URL. This can be done in the application.properties
file:
spring.data.solr.host=http://localhost:8983/solr
Spring Data Solr provides a SolrRepository
interface that we can use to create a Solr repository. For example:
public interface ProductRepository extends SolrRepository<Product, String> {
}
We can now inject and use our ProductRepository
in our code:
@Autowired
private ProductRepository productRepository;
public List<Product> findByName(String name) {
return productRepository.findByName(name);
}
Apache Solr is a versatile search platform that can be used for a variety of different use cases. Some common use cases include:
