Elastic Search Java Api 創建索引結構，添加索引

創建TCP客戶端

Client client = new TransportClient()
             .addTransportAddress(new InetSocketTransportAddress(
                     "localhost", 9300));

創建索引

client.admin().indices().prepareCreate("pages").execute().actionGet();

創建索引結構

XContentBuilder builder=XContentFactory
            .jsonBuilder()
            .startObject()
                .startObject("sina")
                .startObject("properties")
                    .startObject("article_title")
                        .field("type", "string")
                        .field("store", "yes")
                        .field("analyzer","ik")
                        .field("index","analyzed")
                    .endObject()
                    .startObject("article_content")
                        .field("type", "string")
                        .field("store", "no")
                        .field("analyzer","ik")
                        .field("index","analyzed")
                    .endObject()
                    .startObject("article_url")
                        .field("type", "string")
                        .field("store", "yes")
                        .field("index","not_analyzed")
                    .endObject()
                .endObject()
            .endObject()
        .endObject();
PutMappingRequest mapping = Requests.putMappingRequest("pages").type("sina").source(builder);
client.admin().indices().putMapping(mapping).actionGet();

添加索引數據

IndexResponse response = client.prepareIndex("pages", "sina", null)
        .setSource(jsonBuilder()
            .startObject()
                  .field("article_title", Bytes.toString(r.getValue("article".getBytes(), "title".getBytes())))
                   .field("article_content", Bytes.toString(r.getValue("article".getBytes(), "content".getBytes())))
                    .field("article_url", Bytes.toString(r.getValue("article".getBytes(), "url".getBytes())))
               .endObject()
               )
        .execute()
        .actionGet();
            
client.close();
