Java API 操作 ElasticSearch

ElasticSearch Java IN Search

导入

pom

文件

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
</dependency>
           

配置

application.yml

spring:
  data:
    elasticsearch:
      cluster-name: clusterName
      cluster-nodes: <IP>:<PORT>
      repositories:
        enabled: true
      properties:
        node:
          master: false
          name: master
           

编写索引类

@Document(indexName = "myIndex", type = "index_info")
public class MyIndex {
    @Id
    private Integer id;
    private String name;
}
           

编写

Repository

@Repository
public interface MyRepository extends ElasticsearchRepository<MyIndex, Integer> {
}
           

编写

Java Search

查询某个字段匹配多个值：

SELECT id, name FROM MyIndex WHERE field IN ('V1', 'V2')

BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();
queryBuilder.should(QueryBuilders.matchQuery("field", Arrays.asList("V1","V2")).boost(1));
Iterable<Object> search = myRepository.search(customQq);
search.forEach(System.out::println);
           

通过 TransportClient 去 ES 查询

BoolQueryBuilder queryBuilder = QueryBuilders.boolQuery();

TermsQueryBuilder customQq = QueryBuilders.termsQuery("customQq", Arrays.asList("2845243653"));
query.must(customQq);

TermQueryBuilder fraudType = QueryBuilders.termQuery("fraudType", 0);
query.must(fraudType);

SearchResponse response = client
	.prepareSearch("IndexName")
    .setTypes("IndexType")
    .setQuery(queryBuilder)
    // .addAggregation(ValueCountAggregationBuilder)
    .setSize(1)
    .addSort("createTime", SortOrder.DESC)
    .execute().actionGet();

log.info("response: {}", response);
