Java之ES之文檔有則更新無則新增

下面繼續來記錄和更新ES相關操作：

與數據庫的更新操作類似，es同樣也有有則更新無則插入的操作，如下所示：

public class ElasticSearchUtils {
	//有則更新，無則插入
	public void upsertDemo(TransportClient client) {
		try {
			IndexRequest indexRequest = new IndexRequest("index", "type", "1")
				.source(jsonBuilder()
						.startObject()
						.field("name", "Joe Smith")
						.field("gender", "male")
						.endObject());
			UpdateRequest updateRequest = new UpdateRequest("index", "type", "1")
				.doc(jsonBuilder()
						.startObject()
						.field("gender", "male")
						.endObject()
						).upsert(indexRequest);
			client.update(updateRequest).get();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (InterruptedException e) {
			e.printStackTrace();
		} catch (ExecutionException e) {
			e.printStackTrace();
		}
	}
}
