1.建立索引

/**
 * 建立索引
 *
 * @param indexName
 */
public static void createIndex(String indexName) {
    //插入前刪除,以免報錯
    boolean flag = client.admin().indices().exists(new IndicesExistsRequest().indices(new String[]{indexName})).actionGet().isExists();
    if (flag){
        client.admin().indices().prepareDelete(indexName).execute().actionGet();
    }
    client.admin().indices().prepareCreate(indexName).get();
    //client.admin().indices().prepareCreate(indexName)
    //        .setSettings(Settings.builder()
    //                .put("index.number_of_shards", 3)
    //                .put("index.number_of_replicas", 2)
    //        )
    //        .get();
}

 

2.建立mapping

    /**     * 建立mapping,根據需求修改     *     * @param indexName     * @param typeName     */    public static void createMapping(String indexName, String typeName) {        XContentBuilder mappingType = null;        try {            mappingType = jsonBuilder()                    .startObject()                    .startObject(typeName)                    .startObject("properties")                    .startObject("id").field("type", "integer").field("store", "yes").endObject()                    .startObject("Name").field("type", "string").field("store", "yes").field("analyzer", "ik_smart").field("search_analyzer", "ik_smart").endObject()                    .startObject("updatedate").field("type", "date").field("store", "yes").endObject()                    .endObject()                    .endObject()                    .endObject();        } catch (IOException e) {            logger.error("build company mapping failed", e);        }        PutMappingRequest mapping = Requests.putMappingRequest(indexName).type(typeName).source(mappingType);        client.admin().indices().putMapping(mapping).actionGet();        client.admin().indices().prepareRefresh().get();        //client.close();    }
