How to print search query? about elasticsearch-java HOT 6 CLOSED

You can try the logger approach suggested in this stackoverflow post (second answer)
https://stackoverflow.com/questions/60849887/log-json-queries-built-through-elasticsearch-high-level-java-client-for-debuggin

I have tried this approach with below version of ES client, and it works.

co.elastic.clients
elasticsearch-java
7.16.1

from elasticsearch-java.

Part of my code

<dependency>
    <groupId>co.elastic.clients</groupId>
    <artifactId>elasticsearch-java</artifactId>
    <version>7.16.2</version>
</dependency>

search test

import co.elastic.clients.elasticsearch.ElasticsearchClient;
import co.elastic.clients.elasticsearch.core.SearchRequest;
import co.elastic.clients.elasticsearch.core.SearchResponse;
import co.elastic.clients.elasticsearch.core.search.Hit;
import com.tingfeng.vo.IndexProductVo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class EsTest {

    @Autowired
    private ElasticsearchClient client;

    @Test
    public void search() throws Exception {
        SearchRequest searchRequest = SearchRequest.of(s -> s
                .index("demo")
                .query(q -> q
                        .term(t -> t
                                .field("goodsId")
                                .value(v -> v.stringValue("1"))
                        )));

        System.out.println("--- DSL query---：");    // How do I print DSL here？？

        SearchResponse<IndexProductVo> search = client.search(searchRequest, IndexProductVo.class);
        for (Hit<IndexProductVo> hit : search.hits().hits()) {
            System.out.println(hit.source()); // Have the results
        }
    }
}

"elasticsearch-java.jar" How do I print DSL here?

@X-rapido

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        JsonGenerator generator = transport.jsonpMapper().jsonProvider().createGenerator(baos);
        searchRequest.serialize(generator, transport.jsonpMapper());
        generator.close();
        System.out.println(baos);

hi,

before used "elasticsearch-rest-high-level-client.jar", in SearchSourceBuilder.java can print the DSL query

SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(boolQuery);
...
logger.info("=====DSL====="+searchSourceBuilder.toString());

I‘m trying "elasticsearch-java.jar" , please tell me how to print the DSL SearchRequest query?

SearchRequest searchRequest = SearchRequest.of(s -> s
                .index(indexName)
                .query(q -> q
                        .term(t -> t
                                .field("goodsId")
                                .value(v -> v.stringValue("1"))
                        )));

i',m debugging. no found the record。 please help！

The toString() method is overwritten in the "elasticsearch-rest-high-level-client" version, but not in the "elasticsearch-java (8.2.2)" version. As a result, it is not easy to print DSL statements in the development test. I see that this issue is now being optimized and look forward to a new release that addresses this issue.
