elasticsearch,elastic-stack,Java,在Java REST客户端[6.5]API上的ES 6.5中使用映射创建索引
我是弹性搜索的新手，并试图通过跟随文章为应用程序集成自动完成功能 我遵循以下方法来做同样的事情 事件类在Java REST客户端[6.5]API上的ES 6.5中使用映射创建索引,java,
elasticsearch,elastic-stack,Java,
public class Event {
private Long eventId;
private Long catalogId;
private Long orgId;
private String orgName;
private String catalogName;
private String name;
private String eventStatus;
.....
}
public String createEventDocument(Event document) throws Exception {
IndexRequest indexRequest = new IndexRequest(INDEX, TYPE, document.idAsString())
.source(convertEventDocumentToMap(document));
//create mapping with a complete field
IndexResponse indexResponse = client.index(indexRequest, RequestOptions.DEFAULT);
return indexResponse.getResult().name();
}
private Map<String, Object> convertEventDocumentToMap(Event evt) {
return objectMapper.convertValue(evt, Map.class);
}
私有映射convertEventDocumentToMap（事件evt）{
返回objectMapper.convertValue（evt，Map.class）；
}

下面是同样的解决方案。首先使用映射器创建索引并插入数据
public String createEventDocument(Event document) throws Exception {
GetIndexRequest request = new GetIndexRequest();
request.indices(INDEX);
boolean exists = client.indices().exists(request, RequestOptions.DEFAULT);
if(!exists){
createIndexWithMapping();
}
IndexRequest indexRequest = new IndexRequest(INDEX, TYPE, document.idAsString())
.source(convertEventDocumentToMap(document));
//create mapping with a complete field
IndexResponse indexResponse = client.index(indexRequest, RequestOptions.DEFAULT);
return indexResponse.getResult().name();
}
private boolean createIndexWithMapping() throws IOException {
CreateIndexRequest createIndexRequest = new CreateIndexRequest(INDEX);
XContentBuilder builder = XContentFactory.jsonBuilder();
builder.startObject();
{
builder.startObject( "properties" );
{
builder.startObject( "name_suggest" );
{
builder.field( "type", "completion" );
}
builder.endObject();
}
builder.endObject();
}
builder.endObject();
createIndexRequest.mapping(TYPE,builder);
createIndexRequest.timeout(TimeValue.timeValueMinutes(2));
CreateIndexResponse createIndexResponse = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
return createIndexResponse.isAcknowledged();
}
这意味着你在
事件中有一个归档的名称\u建议
，对吗？这意味着你在事件中有一个归档的名称\u建议
，对吗？谢谢。我会检查并更新。updateIndexMapping是一次性活动，还是我们需要对所有插入都执行相同的操作？我昨天尝试过类似的操作XContentBuilder mappingBuilder=jsonBuilder（）.startObject（）。startObject（“您的类型名称”）。startObject（“属性”）。startObject（“您的完成字段”）。字段（“类型”、“完成”）.endObject（）.endObject（）.endObject（）.endObject（）.endObject（）；普特
