Error while creating Elasticsearch API Client(8.0.1) object using Spring Boot

Elastic Stack Elasticsearch
1

I am implementing Elasticsearch 8.0.1 version using Spring Boot. As mentioned in the documentation, this is the pom.xml of my project

<project>

  <dependencies>
    <dependency>
      <groupId>co.elastic.clients</groupId>
      <artifactId>elasticsearch-java</artifactId>
      <version>8.0.1</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>2.12.3</version>
    </dependency>
  </dependencies>

</project>

This is the Configuration class (ElasticsearchConfiguration.java)


    @Bean
    public ElasticsearchClient client() {
        RestClient restClient = RestClient.builder(
                new HttpHost("localhost", 9900)).build();

        // Create the transport with a Jackson mapper
        ElasticsearchTransport transport = new RestClientTransport(
                restClient, new JacksonJsonpMapper());

        // And create the API client
        ElasticsearchClient client = new ElasticsearchClient(transport);

        return client;
    }
}

And the main class includes the following part of the code

    @Bean
    public boolean createTestIndex() throws Exception {
        CreateIndexResponse createResponse = elasticsearchClient.indices().create(
                new CreateIndexRequest.Builder()
                        .index("my-index")
                        .aliases("foo",
                                new Alias.Builder().isWriteIndex(true).build()
                        )
                        .build()
        );
        return true;
    }

}

But when I run the project I am getting below error

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'soSearchApp': Unsatisfied dependency expressed through field 'elasticsearchClient'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'client' defined in class path resource [com/esexperts/config/ElasticsearchConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [co.elastic.clients.elasticsearch.ElasticsearchClient]: Factory method 'client' threw exception; nested exception is java.lang.NoClassDefFoundError: jakarta/json/spi/JsonProvider

Can anyone please help me resolve this issue ?

Wild guess: try adding 'jakarta.json:jakarta.json-api:2.0.1' as an additional dependency and see if that works...

@bhavya does your application have a plugin system or create new classloaders? This may be related to `JsonProvider` : Support specifying the classloader used to resolve the `JsonProvider` or support specifying the `JsonProvider` implementation · Issue #163 · elastic/elasticsearch-java · GitHub that has been fixed but not yet released.

@spinscale thanks :smiley: This worked for me
