新增客戶端：<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>7.4.2</version>
</dependency>
配置檔案：
@Configuration
public class GulimallElasticSearchConfig {
// 單例的
public static final RequestOptions COMMON_OPTIONS;
static {
RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder();
// builder.addHeader("Authorization", "Bearer " + TOKEN);
// builder.setHttpAsyncResponseConsumerFactory(
// new HttpAsyncResponseConsumerFactory
// .HeapBufferedResponseConsumerFactory(30 * 1024 * 1024 * 1024));
COMMON_OPTIONS = builder.build();
}
@Bean
public RestHighLevelClient restHighLevelClient() {
RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(new HttpHost("192.168.56.10", 9200, "http")));
return client;
}
}
構建檢索請求：
1.構建bool - query
2.排序，分頁，高亮
3.聚合（類似於sql中的group by）
客戶端執行檢索
