我正在构建一个查询ElasticSearch的简单REST API。我没有使用ElasticSearch REST API方式，而是使用TCP方式。 我的目标是使用spring启动REST API，它将通过TCP与ElasticSearch通信。
我正在使用ElasticSearch服务器5.6
我有一个ElasticSearchClientFactory，其中包含与ElasticSearch服务器建立连接的代码。无法连接到弹性搜索
ElasticSearchClientFactory.java'buildClient
void buildClient() {
Settings settings = Settings.builder().put("cluster.name", elasticSearchProperties.getClusterName()).build();
TransportClient transportClient = new PreBuiltTransportClient(settings);
if (!StringUtils.isEmpty(elasticSearchProperties.getHostname())
&& !StringUtils.isEmpty(elasticSearchProperties.getPort() + "")) {
try {
transportClient.addTransportAddress(
new InetSocketTransportAddress(InetAddress.getByName(elasticSearchProperties.getHostname()),
elasticSearchProperties.getPort()));
transportClient.connectedNodes();
this.client = transportClient;
} catch (UnknownHostException e) {
LOGGER.error("Unable to Connect to ElasticSearch,UnknownHost" + elasticSearchProperties.getHostname());
}
} else {
LOGGER.error("Missing ElasticSearch configuration hostname and portNumber");
throw new DataAccessException(CommonConstants.DAE001, "Unable to connect to ElasticSearch");
}
}
pom.xml中包含了以下相关ElasticSearch
