本文介绍如何在Elasticsearch中通过Java客户端创建索引，并演示了如何将自定义对象转换为JSON字符串进行存储。此外，还展示了设置RequestOptions的具体方式。

以下内容都是参考此链接https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-create-index.html

1.ElasticConfiguration类中添加如下配置

    private static final RequestOptions COMMON_OPTIONS;
    static {
        RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder();
//        builder.addHeader("Authorization", "Bearer " + TOKEN);
//        builder.setHttpAsyncResponseConsumerFactory(
//                new HttpAsyncResponseConsumerFactory
//                        .HeapBufferedResponseConsumerFactory(30 * 1024 * 1024 * 1024));
        COMMON_OPTIONS = builder.build();
    }

2.测试

下面是使用最常用的方法来保存索引

    @Test
    public  void indexData() throws IOException {
        IndexRequest indexRequest = new IndexRequest("users");
//        indexRequest.source("name","libai","age",13);
        User user = new User();
        user.setName("libai");
        user.setAge(3000);
        user.setSex("m");

        String jsonString = JSON.toJSONString(user);


        indexRequest.source(jsonString, XContentType.JSON);

        IndexResponse response = client.index(indexRequest, RequestOptions.DEFAULT);

        System.out.println(response);
    }

控制台成功打印索引
