@Component("ElasticsearchRestClient")
@Configuration
public class ElasticsearchRestClient {

    private static String host = "你的es地址";

    private static  int port = 9200;

    private static String userName = "你的账号";

    private static String passWord = "你的密码";
    
    public static RestClient getRestClient() {
        //初始化ES操作客户端
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(userName, passWord));  //es账号密码
        esClient = new RestHighLevelClient(
            RestClient.builder(
                new HttpHost(host, port)
            ).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                    httpClientBuilder.disableAuthCaching();
                    return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
                }
            })
        );
        return esClient.getLowLevelClient();
    }

}

我使用的ES版本是6.3.2的所有使用的pom.xml是（注意:使用的版本一定要与你的ES版本相同！）
