第一步:引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
<version>2.2.5.RELEASE</version>
</dependency>
第二步:配置yml文件,在spring下面加上这个
elasticsearch:
rest:
# ip是服务器ip地址
uris: http://127.0.0.1:9200
然后启动项目,看到出现这个就是成功了
第三步: 创建一个常量类,用于存储我们一会儿要用到的名称
public class OrderEs {
public static final String INDEX_NAME = "order_index";
public static final String ID = "id";
public static final String ORDER_NO = "order_no";
public static final String ORDER_BUYER = "order_buyer";
public static final String ORDER_PHONE = "order_phone";
public static final String REAL_PAY = "real_pay";
public static final String ACCOUNT = "account";
}
第四步:创建Es实体类,注意要加上@Document注解
@Document(indexName = OrderEs.INDEX_NAME)
@Data
public class OrderEsPO {
@Id
@Field(type = FieldType.Keyword,name = OrderEs.ID)
private String id;
@Field(type = FieldType.Keyword,name = OrderEs.ORDER_NO)
private String orderNo;
@Field(type = FieldType.Keyword,name = OrderEs.ORDER_BUYER)
private String orderBuyer;
@Field(type = FieldType.Keyword,name = OrderEs.ORDER_PHONE)
private String orderPhone;
@Field(type = FieldType.Keyword,name = OrderEs.REAL_PAY)
private String realPay;
@Field(type = FieldType.Keyword,name = OrderEs.ACCOUNT)
private String account;
}
第五步:写测试接口,这里展示了插入和查询两个方法
@RestController
@RequestMapping("/order")
@CrossOrigin
public class OrderController
@Resource
private ElasticsearchRestTemplate elasticsearchRestTemplate;
/**
* es插入
*
* @return {@link String}
*/
@GetMapping("/esinsert")
@Transactional
public String esInsert(){
OrderEsPO orderEsPO = new OrderEsPO();
orderEsPO.setOrderNo("1234455");
orderEsPO.setOrderBuyer("张三");
orderEsPO.setOrderPhone("13191892075");
orderEsPO.setRealPay("100000");
orderEsPO.setAccount("1008611");
elasticsearchRestTemplate.save(orderEsPO);
return "success";
}
/**
* es搜索
*
* @param orderEsPO 订单es参数
* @return {@link String}
*/
@GetMapping("/essearch")
@Transactional
public String esSearch(OrderEsPO orderEsPO){
/**构造查询对象**/
BoolQueryBuilder booleanQueryBuilder = QueryBuilders.boolQuery();
/**编写查询条件**/
booleanQueryBuilder.should(QueryBuilders.termQuery(OrderEs.ORDER_NO,orderEsPO.getOrderNo()));
/**构造query对象**/
NativeSearchQuery nativeSearchQuery = new NativeSearchQuery(booleanQueryBuilder);
/**搜索**/
SearchHits<OrderEsPO> search = elasticsearchRestTemplate.search(nativeSearchQuery, OrderEsPO.class, IndexCoordinates.of(OrderEs.INDEX_NAME));
List<OrderEsPO> collect = search.getSearchHits().stream().map(SearchHit::getContent).collect(Collectors.toList());
return collect.toString();
}
}
然后我们启动项目,先调用插入接口,由于这个索引一开始是不存在的,第一次调用后会默认创建索引,然后打开我们的可视化界面,就能看到这里的索引
再调用查询,就能看到如下信息了
