Elasticsearch整合-续集-index

在配置类中继续添加配置
相关配置的官网地址：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-low-usage-requests.html#java-rest-low-usage-request-options

当前配置类：

@Configuration
public class VmElasticsearchConfig {

    @Bean
    public RestHighLevelClient esRestClient() {
        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("192.168.23.145", 9200, "http")));
                        //没有集群不用指定多个
//                        new HttpHost("localhost", 9201, "http"))
        return client;
    }

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

测试添加：
文档地址：https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.4/java-rest-high-document-index.html
有多种方式，详情见文档

index测试：

  @Test
    public void indexData() throws IOException {
      IndexRequest indexRequest = new IndexRequest("users");
      indexRequest.id("1");//数据的id
//      indexRequest.source("userName","zhangsan","age","18");  第一种方式
        User user = new User();
        user.setUserName("zhangsan");
        user.setAge(18);
        user.setGender("男");
        String jsonString = JSON.toJSONString(user);
        indexRequest.source(jsonString, XContentType.JSON);//数据的内容

        //执行操作
        IndexResponse index = client.index(indexRequest, VmElasticsearchConfig.COMMON_OPTIONS);

        //提取有用的响应数据
        System.out.println(index);
    }
