Elasticsearch spring implementation error

Question

I have a interface which has function used to query ElasticSearch. It extends the ElasticsearchRepository for doing it.

public interface HouseholdRepository extends ElasticsearchRepository<SearchHouseholdESBean, String> {
    List<SearchHouseholdESBean> findByPhoneNumberAndActiveInd(String phoneNumber, String activeInd);

The problem is how do i call this in my business class where i need to get the results. This being an interface , i can't create an object of this to call the methods. Also, the implementation is implicit to the jars in the Elastic Search.

@georges van I tried something like :- "@Autowired private HouseholdRepository householdRepository;" in the implementation class but the object is null. What can be the reason for this ? — jatin bajaj

To use elastichsearch repositories you must follow the next steps: 1. add annotation @EnableElasticsearchRepositories on your SpringBootApplication

@SpringBootApplication
@EnableElasticsearchRepositories
public class Application {
//...

2. Make sure that the interface HouseholdRepository is scanned by the spring-boot application. You can simple achieve this by placing it under the same root package as your Application class.

3.You will just @Autowire HouseholdRepository in your service without further changes. The idea behind spring boot data is that the code will be generated based on that interface.

OBS: make sure that you have the proper project dependencies. You should depend on spring-boot-starter-data-elasticsearch to avoid extra configuration effort.

Thanks for the response. I have following in the configuration file where i instatiate my transport client "@ EnableElasticsearchRepositories @ Configuration @ ComponentScan(basePackages = {"com.amdocs.bda.ccr"}) public class CCRServicesConfig { @ Bean public ElasticsearchOperations elasticsearchTemplate() {" Will this suffice or i have to add "@ SpringBootApplication" annotation to the same file as well
