是否可以使用Spring的注释为ElasticSearch中的映射定义完成建议？

Question

@Document(indexName="ws",type="vid")
public class Vid {
    @Id 
    private String id;

    @Field(type=FieldType.String, index=FieldIndex.not_analyzed)
    private List<String> tags;
}

{ 
    "id" : "someId",
    "tags" : [ "one", "two", "three" ]
}

{
    "vid": {
        "properties": {
            "id": {
                "type": "string"
            },
            "tags": {
                "type": "completion",
                "index_analyzer": "simple",
                "search_analyzer": "simple",
                "payloads": true
            }
        }
    }
}

{
    "id": "someId",
    "tags": {
        "input": [ "one", "two", "three" ]
    }
}

{
    "id": "someId",
    "tags": [ "one", "two", "three" ],
    "tags_suggest": {
        "input": [ "one", "two", "three" ]
    }
}

最后，我在http://docs.spring.io/spring-data/elasticsearch/docs/current/api/index.html？org/springframework/data/elasticsearch/core/completity/completion.html的spring-data-elasticsearch中找到了这个javadoc页面。我确信这个类与完成暗示器有关，但我不知道如何使用它。

我是否可以使用Spring注释来定义completation suggester的Elasticsearch映射？

Answer 1

当然可以..

您可以这样配置您的实体：

...
import org.springframework.data.elasticsearch.core.completion.Completion;
...

@Document(indexName = "test-completion-index", type = "annotated-completion-type", indexStoreType = "memory", shards = 1, replicas = 0, refreshInterval = "-1")
public class YoutEntity {

    @Id
    private String id;
    private String name;

    @CompletionField(payloads = true, maxInputLength = 100)
    private Completion suggest;

    ...
}
