Spring Solr Auto-Configuration

By -
Apache Solr is a search engine. Spring Boot offers basic auto-configuration for the Solr 5 client
library and the abstractions on top of it provided by Spring Data Solr.

There is a spring-bootstarter-data-solr “Starter” for collecting the dependencies in a convenient way.

Connecting to Solr

You can inject an auto-configured SolrClient instance as you would any other Spring bean. By
default, the instance tries to connect to a server at localhost:8983/solr. The following example
shows how to inject a Solr bean:

@Component
public class MyBean {
private SolrClient solr;
@Autowired
public MyBean(SolrClient solr) {
this.solr = solr;
}
// ...
}

If you add your own @Bean of type SolrClient, it replaces the default.

Spring Data Solr Repositories

Spring Data includes repository support for Apache Solr. As with the JPA repositories discussed
earlier, the basic principle is that queries are automatically constructed for you based on method
names.
In fact, both Spring Data JPA and Spring Data Solr share the same common infrastructure. You
could take the JPA example from earlier and, assuming that City is now a @SolrDocument class rather
than a JPA @Entity, it works in the same way.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
