配置es连接

spring:
  data:
    elasticsearch:
      cluster-name: elasticsearch
      cluster-nodes: 127.0.0.1:9300

准备query接收查询条件

@Data
public class CarSearchQuery extends BaseQuery {
   
    private Long carType;
    private Double maxPrice;
    private Double minPrice;

    //0 以下 1 以上
    private Integer carAgeType;
    private Integer carAge;

    //是否超值
    private Integer costEffective;
    //急售
    private Integer rushSale;
    //准新车
    private Integer quasiNewCar;
    //可迁全国
    private Integer transitiveCountry;

    //排序字段
    private String sortField;
    //排序类型 desc降序 asc升序号
    private String sortType;

    private Double longitude;
    private Double latitude;
    private Double distance;
    private Long shopId;
}

准备Controller

@RestController
@RequestMapping("/car/search")
public class CarSearchController {
   

    @Autowired
    private ICarSearchService carSearchService;

    @PostMapping
    public AjaxResult search(@RequestBody CarSearchQuery query) {
   
        PageList<CarDoc> search = carSearchService.search(query);
        return AjaxResult.me().setData(search);
    }
}

定义Document文档类型

@Data
@AllArgsConstructor
@NoArgsConstructor
@Document(indexName = "example-car", type = "car")
public class CarDoc {
   

    @Id
    private Long id;
    @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart")
    private String title;

    @Field(type = FieldType.Keyword)
    private String cover;

    @Field(type = FieldType.Double)
    private BigDecimal salePrice;

    @Field(type = FieldType.Double)
    private BigDecimal costPrice;

    @Field(type = FieldType.Integer)
    private Integer isNew;

    @Field(type = FieldType.Date)
    private Date registerTime;

    @Field(type = FieldType.Double)
    private Double mileAge;

    @Field(type = FieldType.Long)
    private Long shopId;

    @MultiField(mainField = @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart"),
            otherFields = {
   @InnerField(type = FieldType.Keyword, suffix = "keyword")})
    private String shopName; // @MultiField对同一字段应用不同的分析器或存储策略,这里既可以将该字段按照text进行拆分，也可以作为keyword进行查询
    
    @Field(type = FieldType.Keyword)
    private String shopAddress;
    @Field(type = FieldType.Date)
    private Date onSaleTime;
    @Field(type = FieldType.Integer)
    private Integer costEffective;
    @Field(type = FieldType.Integer)
    private Integer rushSale;
    @Field(type = FieldType.Integer)
    private Integer quasiNewCar;
    @Field(type = FieldType.Integer)
    private Integer transitiveCountry;

    @Field(type = FieldType.Long)
    private Long typeId;

    @MultiField(mainField = @Field(type = FieldType.Text, analyzer = "ik_smart", searchAnalyzer = "ik_smart"),
            otherFields =
