springboot项目spring-data-elasticsearch添加x-pack身份认证（elasticsearch6.x）

依赖

注意：依赖版本可能会不兼容，注意根据自己的去适配（本文使用的是es6.6版本）

yml配置

elasticSearch:
  host: 127.0.0.1
  port: 9300
  cluster-name: elasticsearch
  user.password: elastic:123456

java配置

注意：需要在类上面加@Configuration注解

    /**
     * es集群读取路径
     */
    public static final String X_PACK_ES_NAME="cluster.name";
    /**
     *x-pack用户名密码读取路径
     */
    public static final String X_PACK_USER="xpack.security.user";

    @Value("${elasticSearch.cluster-name}")
    private String esClusterName;
    @Value("${elasticSearch.host}")
    private String esHost;
    @Value("${elasticSearch.port}")
    private int esPort;
    @Value("${elasticSearch.user.password}")
    private String esUserPassword;

    private final Logger LOGGER = LoggerFactory.getLogger(BeanConfiguration.class);

    /**
     * elasticsearch客户端注入（配置）
     *
     * @return
     * @throws UnknownHostException
     */
    @Bean
    public TransportClient transportClient() throws UnknownHostException {
        TransportClient client = new PreBuiltXPackTransportClient(Settings.builder()
                .put(X_PACK_ES_NAME, esClusterName)
                .put(X_PACK_USER, esUserPassword)
                .build())
                .addTransportAddress(new TransportAddress(InetAddress.getByName(esHost), esPort));
        return client;
    }

然后就可以访问了
