RestHighLevelClient（操作ES的客户端，使用时注入bean即可)

 public RestHighLevelClient restHighLevelClient() {

        RestClientBuilder rclientBuilder = RestClient.builder(new HttpHost(host, port, "http"))
                .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                    @Override
                    public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                        return httpClientBuilder
                                .setKeepAliveStrategy((response, context) -> Duration.ofMinutes(5).toMillis());
                    }
                });
        return new RestHighLevelClient(rclientBuilder);

DeleteRequest批量删除
