Java elasticsearch彈性數據集不同索引字段名稱

我使用elasticsearch java-api與spring-data結合使用，並且在索引文檔時遇到問題。我想要一個索引字段的不同名稱。這意味着不一樣的Java代碼：Java elasticsearch彈性數據集不同索引字段名稱

的domainObject：

@Document(indexName = "testindex", type = "message") 
public class MessageObject { 

@Id 
private String unid; 

@FieldNameInElasticIndex(value = "javaMessage") // I want anything like that 
private String message; 

private String secondMessage; 

private String thirdMessage; 

... 

getters & setters 

... 

}

接口：

public interface MessageObjectRepository extends ElasticsearchRepository<MessageObject, Long> { 


}

服務：

@Component 
public class MessageService { 

    @Autowired 
    private MessageObjectRepository repository; 


    public void addRegistrationObject(MessageObject msg) { 

     repository.save(msg); 
    } 
}

所以....

是否可以更改名稱，因此該指數將是這樣的：的

"hits": { 
    "total": 1, 
    "max_score": 1, 
    "hits": [ 
     { 
     "_index": "testindex", 
     "_type": "message", 
     "_id": "00113B325ED357B7C1257E2D001D5B4B", 
     "_score": 1, 
     "_source": { 
      "unid": "00113B325ED357B7C1257E2D001D5B4B", 
      "javaMessage": "Hello", // <--- this is what I want (javaMessage) 
      "secondMessage": null, 
      "thirdMessage": "Third",

代替

"hits": { 
    "total": 1, 
    "max_score": 1, 
    "hits": [ 
     { 
     "_index": "testindex", 
     "_type": "message", 
     "_id": "00113B325ED357B7C1257E2D001D5B4B", 
     "_score": 1, 
     "_source": { 
      "unid": "00113B325ED357B7C1257E2D001D5B4B", 
      "message": "Hello", // <--- this is NOT what I want (java name: message) 
      "secondMessage": null, 
      "thirdMessage": "Third",

？

有你試過'@JsonProperty（「javaMessage」）'？ – Val

它的工作原理，謝謝:) –

的想法很簡單，就是用場上的@JsonProperty批註，給你想要的JSON序列化過程中使用的名稱：

@JsonProperty("javaMessage") 
private String message;

http://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/中沒有_single_提到'@ JsonProperty'！這在文檔中如何被忽略？ –

Val發佈正確的解決方案：

@JsonProperty("name")
