pom.xml

    org.elasticsearch.client    transport    6.8.8    org.elasticsearch    elasticsearch    6.8.8    org.apache.logging.log4j    log4j-api    2.13.2    org.apache.logging.log4j    log4j-core    2.13.2    junit    junit    4.12

创建连接

@Beforepublic void prepare() throws Exception{index = "neptune";    type = "doc";    Settings settings = Settings.builder().put("cluster.name","hysg-test-cluster").build();    //创建客户端     client = new PreBuiltTransportClient(settings)            .addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"),9300));}

获取一条数据

@Testpublic void getOne()throws Exception{    GetResponse response = client.prepareGet(index, type,1).get();    System.out.println(response);}

根据查询条件批量删除数据

@Testpublic void deleteByQueryField()throws Exception{    BulkByScrollResponse response =            DeleteByQueryAction.INSTANCE.newRequestBuilder(client)                    .filter(QueryBuilders.matchQuery("IP", "127.0.0.1"))                    .source(index)                    .get();    long deleted = response.getDeleted();    System.out.println(deleted);}
