1、默认集群连接
Client client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
2、自定义集群连接
Settings settings = Settings.settingsBuilder().put("cluster.name", "cluster-lhy").build();
Client client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
3、index创建
client.admin().indices().prepareCreate("phone12").get();
4、mapping创建
有四种方式，只提倡前两种（json字符串格式和XContentBuilder），都是一个方法，不同类型参数
Client client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
new XContentFactory();
XContentBuilder builder=XContentFactory.jsonBuilder()
.startObject()//注意不要加index和type
.startObject("properties")
.startObject("id1").field("type", "integer").field("store", "yes").endObject()
.startObject("kw1").field("type", "string").field("store", "yes").field("analyzer", "ik").endObject()
.startObject("edate33").field("type", "date").field("store", "yes").endObject()
.endObject()
.endObject();
/**
* 创建并添加方式1
*/
/* client.admin().indices().prepareCreate("twitter1")
.addMapping("tweet", "{\n" +
" \"tweet\": {\n" +
" \"properties\": {\n" +
" \"message1\": {\n" +
" \"type\": \"string\",\n" +
" \"indexAnalyzer\": \"ik\"\n"+

" }")
.get();*/
/**

*/
//client.admin().indices().prepareCreate("phone1").addMapping("jingdong", builder).get();
/**

*/
/* client.admin().indices().preparePutMapping(new String[]{"phone"})
.setType("jingdong")
.setSource("{\n" +
" \"properties\": {\n" +
" \"nameaaa\": {\n" +
" \"type\": \"string\"\n" +
" }\n" +
" }\n" +
"}")
.get();*/
/**
* 修改type中属性 方式2
*/
/*client.admin().indices().preparePutMapping(new String[]{"phone"})
.setType("jingdong").setSource(builder)
.get();*/
/**
* 方式3不推荐
*/
/* Map map=new HashMap();
Map map2=new HashMap();
map2.put("type", "string");
Map map3=new HashMap();
map.put("ooooooooo",map2);
map3.put("properties", map);
client.admin().indices().preparePutMapping(new String[]{"phone"})
.setType("jingdong").setSource(map3)

5、2.3.4版本elasticsearch的ik分词器配置注意
不需要再在elasticsearch配置文件elasticsearch.yml中配置
1.从https://github.com/medcl/elasticsearch-analysis-ik下载elasticsearch-analysis-ik-master.zip
2.解压elasticsearch-analysis-ik-master.zip
unzip elasticsearch-analysis-ik-master.zip
3.进入elasticsearch-analysis-ik-master，编译源码
cd elasticsearch-analysis-ik-master
mvn clean package
编译后会放在 elasticsearch-analysis-ik-master/target/releases目录下
![]()
4.在$ES_HOME/plugins文件夹下创建ik
mkdir ik
5、找到将编译后生成的elasticsearch-analysis-ik-1.9.4.zip解压到$ES_HOME/plugins/ik下
![]()
测试分词器curl -XPOST "http://localhost:9200/索引/_analyze?analyzer=ik&pretty=true&text=我是中国人"
