Java配置带密码的ElasticSearch客户端

@Configuration
public class ElasticSearchConfiguration {

    public static final String username = "elastic";

    public static final String password = "你的密码";
    //通用设置项
    public static final RequestOptions COMMON_OPTIONS;

    static {
        RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder();

        COMMON_OPTIONS = builder.build();
    }

    @Bean
    public RestHighLevelClient esRestClient() {
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(AuthScope.ANY,
                new UsernamePasswordCredentials(username, password));  //es账号密码


        RestHighLevelClient client = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("ip地址", 端口号, "http")
                ).setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                    public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                        httpClientBuilder.disableAuthCaching();
                        return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
                    }
                })
        );
        return client;
    }


}

此方案在6.x以及7.x版本下测试成功
