Spring Boot(v.2.3.1 and above) + Elasticsearch

If you are like me who have spent endless hours trying to connect ElasticSearch with Spring Boot with no luck yet, this is for you!

There are probably hundreds of tutorials out there but none of them explicitly describe on how to configure a Spring Boot (versions 2.3.1 and above) with Elasticsearch.

Both, Elasticsearch and Spring Boot have been constantly rolling out newer versions, better than the previous ones at the same time making it painstakingly difficult to manage compatibility issues.

Most of the tutorials and examples on Stackoverflow and the Internet are based upon an older version of SB wherein it is necessary to define a RestHighLevelClient

Even the official documentation of Elastic recommends using a RestHighLevelClient with Spring.

All of the above makes sense with a older version of Spring Boot or if you are using a Spring web application with a separate configuration for Spring Data Elastic.

Since v2.3.1, in order to configure Elasticsearch with your SpringBoot application, all you have to do is add the following dependency-

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

That’s it. Spring Boot provides a default ElasticsearchRestTemplate. ElasticsearchRestTemplate is part of release 4 of Spring Data ES which provides out of box support for CRUD operations on ES.

Example to add documents to an index named products —


IndexQuery indexQuery = new IndexQueryBuilder()
        .withId(productDocument.getProductID().toString())
        .withObject(productDocument)
        .build();
return elasticsearchRestTemplate.index(indexQuery, IndexCoordinates.of("products"));

That’s all!

There’s no need of creating another RestHighLevelClient or managing any other version specific dependencies to make this work.

More information on ElasticsearchRestTemplate can be found on the Spring official ES doc here.

Hope this helps!

Add JSON LD schema with NextJS in these 2 steps.

We recently upgraded the NextJS version for our CMS portal at Storeplum and decided to add structured data for each page.

Found a npm library but it was kind of outdated. After a lot of searching, I found that the solution was fairly straightforward.

All I did was added the schema definition into a script tag as below-

Get your schema definition -

let schema = {
  "@context": "https://schema.org",
  "@type": "Article",
  "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "example.com/articleURL"
  },
  "headline": "Article title",
  "image": [
    spContent.metaData.twitterCard
   ],
  "datePublished": spContent.created_at,
  "dateModified": spContent.metaData.articleModifiedTime,
  "author": [{
      "@type": "Person",
      "name": "Json Bourne",
      "url": "example.com/jbourne"
    }],
  "publisher": {
      "@type": "Organization",
      "name": "abc",
      "logo": {
        "@type": "ImageObject",
        "url": "example.com/image"
      }
    },
  "description": "some description"

};

Put your data string inside a script tag as below

 <script 
            type='application/ld+json'
            dangerouslySetInnerHTML={{ __html: JSON.stringify(schema) }} />

That's all! You can verify your changes once you deploy using this tool by Google.
