pom文件配置：

<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
    			<exclusions>
    				<exclusion>
    					<groupId>org.elasticsearch.client</groupId>
    					<artifactId>transport</artifactId>
    				</exclusion>
    			</exclusions>
    		</dependency>
    		<dependency>
    			<groupId>org.elasticsearch.client</groupId>
    			<artifactId>x-pack-transport</artifactId>
    			<version>5.5.0</version>
    		</dependency>

ElasticsearchTemplate和TransportClient的配置  
注意：elastisearch开通了ssl（xpack.security.transport.ssl.enabled: true），如果要用9300端口来通信，是要设置ca证书，和客户端的key和客户端证书，否则无法通过es认证。

@Override
        public ElasticsearchTemplate build() { 
    
            return new ElasticsearchTemplate(transportClient());
        }
    
        private TransportClient transportClient() { 
    
            try { 
                Settings.Builder settings = Settings.builder().put("cluster.name", clusterName);
    
                if(!StringUtil.isEmpty(userPass)&&!userPass.equals("''")){ 
                    settings.put("xpack.security.user", userPass);
                    settings.put("xpack.ssl.certificate_authorities", caCrt);
                    settings.put("xpack.ssl.key", clientKey);
                    settings.put("xpack.ssl.certificate", clientCrt);
                    if (caCrt != null && !StringUtil.isEmpty(caCrt)) { 
                        settings.put("xpack.security.transport.ssl.enabled", "true");
                    }
                }
    
                TransportClient client = new PreBuiltXPackTransportClient(settings.build());
    
                Map<String, Integer> nodeMap = getNodeMap();
                for (Map.Entry<String, Integer> entry : nodeMap.entrySet()) { 
    
                    client.addTransportAddress(
                            new InetSocketTransportAddress(InetAddress.getByName(entry.getKey()), entry.getValue()));
                }
    
                return client;
            }catch (Exception e){ 
                e.printStackTrace();
            }
            return null;
        }
