        HttpHost host = new HttpHost("es的ip地址", 9200, HttpHost.DEFAULT_SCHEME_NAME);
        RestClientBuilder builder = RestClient.builder(host);

        // 若elasticsearch有密码则配置
        CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("账号", "密码"));
        builder.setHttpClientConfigCallback(f -> f.setDefaultCredentialsProvider(credentialsProvider));

        return new RestHighLevelClient(builder);
    }

     @Bean
     public ElasticsearchRestTemplate elasticsearchRestTemplate() {
     return new ElasticsearchRestTemplate(this.elasticsearchClient());
