运行方法-删除索引

    //删除索引库
    @Test
    public void testDeleteIndex() throws IOException {
        //删除索引对象
        DeleteIndexRequest deleteIndexRequest = new DeleteIndexRequest("xc_course");
        //操作索引的客户端
        IndicesClient indices = client.indices();
        //执行删除索引
        DeleteIndexResponse delete = indices.delete(deleteIndexRequest);
        //得到响应
        boolean acknowledged = delete.isAcknowledged();
        System.out.println(acknowledged);

    }

创建索引和创建映射

    //创建索引库
    @Test
    public void testCreateIndex() throws IOException {
        //创建索引对象
        CreateIndexRequest createIndexRequest = new CreateIndexRequest("xc_course");
        //设置参数
        createIndexRequest.settings(Settings.builder().put("number_of_shards","1").put("number_of_replicas","0"));
        //指定映射
        createIndexRequest.mapping("doc"," {\n" +
                " \t\"properties\": {\n" +
                "            \"studymodel\":{\n" +
                "             \"type\":\"keyword\"\n" +
                "           },\n" +
                "            \"name\":{\n" +
                "             \"type\":\"keyword\"\n" +
                "           },\n" +

                "             \"type\":\"text\",\n" +
                "             \"index\":false\n" +
                "           }\n" +
                " \t}\n" +
                "}", XContentType.JSON);
        //操作索引的客户端
        IndicesClient indices = client.indices();
        //执行创建索引库
        CreateIndexResponse createIndexResponse = indices.create(createIndexRequest);
        //得到响应
        boolean acknowledged = createIndexResponse.isAcknowledged();
        System.out.println(acknowledged);
