使用 Spring Elasticsearch 数据存储库构建查询

Question

我正在使用elasticsearch 6，和Spring数据jpa来查询。我写了这段代码：

持久对象：

@Document(indexName="vehicle_event", type="vehicle_event")
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class VehicleEventEL {

    @Id
    private String id;
    private Long id_vehicle;
    private Long id_road;
    private Float latitude;
    private Float longitude;
    private String name_road;
    private Date timestamp;

}

存储库：

@Component
public interface VehicleEventELRepository extends ElasticsearchRepository<VehicleEventEL, String> {

    Page<VehicleEventEL> findByTimestampBetween(String startTime, String endTime, Pageable page);

    Page<VehicleEventEL> findByTimestampBetweenAndId_vehicleEquals(String startTime, String endTime, Long id_vehicle, Pageable page);
}

方法 findByTimestampBetween 有效。

方法 findByTimestampBetweenAndId_vehicleEquals 不起作用，并出现以下错误：

Error creating bean with name 'vehicleEventELRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property vehicle found for type String! Traversed path: VehicleEventEL.id.

我找不到解决方案。

下划线是一个问题，解决方案是遵循 java 命名约定。 Spring documentation 说：

To resolve this ambiguity you can use _ inside your method name to manually define traversal points. So our method name would be as follows:

List<Person> findByAddress_ZipCode(ZipCode zipCode);

Because we treat the underscore character as a reserved character, we strongly advise following standard Java naming conventions (that is, not using underscores in property names but using camel case instead).

如果您不能更改名称，一种选择是使用@Query 注释。
