## 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）

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
                <exclusions>
                    <exclusion>

                        <artifactId>transport</artifactId>
                    </exclusion>
                </exclusions>

## 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
