How to show elasticsearch queries in spring boot application

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;    }

I tried other answer and it didn't worked in spring boot 2.2.2 and elasticsearch 6.7.2, the below worked for me probably because I use the RestHighLevelClient, to get the request and response body I had to enable the apache http logging in the application.properties files like below

logging.level.org.elasticsearch.client=TRACElogging.level.org.apache.http=TRACE

In Spring Boot 2 you can enable query debug with the following:

logging.level.org.springframework.data.elasticsearch.core=DEBUG

And the generated log will be something like:

{  "from" : 0,  "size" : 10,  "query" : {    "bool" : {      "must" : [        {          "query_string" : {            "query" : "some string",            "fields" : [              "nome^1.0"            ],            "use_dis_max" : true,            "tie_breaker" : 0.0,            "default_operator" : "and",            "auto_generate_phrase_queries" : false,            "max_determinized_states" : 10000,            "enable_position_increments" : true,            "fuzziness" : "AUTO",            "fuzzy_prefix_length" : 0,            "fuzzy_max_expansions" : 50,            "phrase_slop" : 0,            "escape" : false,            "split_on_whitespace" : true,            "boost" : 1.0          }        }      ],      "disable_coord" : false,      "adjust_pure_negative" : true,      "boost" : 1.0    }  },  "version" : true}

Best regards.
