For spring-data-cassandra we have a special @CountQuery annotation to solve this issue. Is there a

问题 I am implementing a spring-boot microservice for elasticsearch (es) operations using springdata APIs. My documents that are indexed in es are huge with multiple fields (more than 100).

When I add field @Transient private Long id; in my Project entity then I am able to retrieve results correctly. But I do not want to add this field because I have already defined primary key named projectId . There is annotation @Id for that field also, so why my field projectId is not

问题 Summary Recently we upgraded to Spring Data Elasticsearch 4.x. Part of this major release meant that Jackson is no longer used to convert our domain objects to json (using MappingElasticsearchConverter instead) [1]. This means we are now forced to add a new id field to all our documents. Previously we had domain objects like this: import org.springframework.data.annotation.Id; public ESDocument { @Id private String id; private String field1; @JsonIgnore public String getId() { return id; }
