本文详细介绍了如何使用Java创建一个Elasticsearch客户端，创建索引、定义索引结构，并添加索引数据的过程。

创建TCP客户端

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

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

创建索引结构
	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();

添加索引数据		
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();
