elasticsearchHow can I use Elasticsearch with Java Spring Boot?

Elasticsearch can be used with Java Spring Boot in order to build powerful search applications. The following steps can be used to configure Elasticsearch with Spring Boot:

1. Add the required dependencies to the project's pom.xml file:

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-elasticsearch</artifactId>
  <version>4.0.0.RELEASE</version>
</dependency>

2. Configure the application.yml file with the necessary cluster information:

spring:
  data:
    elasticsearch:
      cluster-name: my-cluster-name
      cluster-nodes: localhost:9300

3. Create an ElasticsearchTemplate bean in the Spring configuration class:

@Bean
public ElasticsearchTemplate elasticsearchTemplate() {
    return new ElasticsearchTemplate(client());
}

4. Create an ElasticsearchOperations bean in the Spring configuration class:

@Bean
public ElasticsearchOperations elasticsearchOperations() {
    return new ElasticsearchTemplate(client());
}

5. Use the ElasticsearchTemplate and ElasticsearchOperations beans to perform search operations.
