How to show elasticsearch queries in spring boot application

Question

I am trying elastic search in spring boot application and I would like to debug on queries executed by ElasticsearchRepository.

tried logging.level.org.elasticsearch.index.search.slowlog.query=INFO spring.data.elasticsearch.properties.index.search.slowlog.threshold.query.info=1ms but I didn't see the query print in log

Answer 1

Using Springboot 2.2.6, and RestHighLevelClient, the following worked:

logging.level.org.springframework.data.elasticsearch.client.WIRE : trace

This is also documented in springboot-data-elasticsearch

However, you need to pay attention to initialize your RestHighLevelClient bean in the same way stated in the documentation. I.e, using the ClientConfiguration builder. At first I created the bean as new RestHighLevelClient() and it didn't work. Example:

    @Bean(destroyMethod = "close")
    public RestHighLevelClient restClient() {

        ClientConfiguration clientConfiguration = ClientConfiguration.builder()
                .connectedTo(esHost +":" + esPort).usingSsl()
                .build();

        RestHighLevelClient client = RestClients.create(clientConfiguration).rest();
        return client;

    }
