您应该自己定义它，因为NodeClientFactoryBean有一个选项，
http.enabled但是ElasticSearchAutoConfiguration尚未设置。
@Configuration@EnableConfigurationProperties(ElasticsearchProperties.class)public class ElasticsearchConfiguration implements DisposableBean { private static Log logger = LogFactory.getLog(ElasticsearchConfiguration.class); @Autowired private ElasticsearchProperties properties; private NodeClient client; @Bean public ElasticsearchTemplate elasticsearchTemplate() { return new ElasticsearchTemplate(esClient()); } @Bean public Client esClient() { try { if (logger.isInfoEnabled()) { logger.info("Starting Elasticsearch client"); } NodeBuilder nodeBuilder = new NodeBuilder(); nodeBuilder .clusterName(this.properties.getClusterName()) .local(false) ; nodeBuilder.settings() .put("http.enabled", true) ; this.client = (NodeClient)nodeBuilder.node().client(); return this.client; } catch (Exception ex) { throw new IllegalStateException(ex); } } @Override public void destroy() throws Exception { if (this.client != null) { try { if (logger.isInfoEnabled()) { logger.info("Closing Elasticsearch client"); } if (this.client != null) { this.client.close(); } } catch (final Exception ex) { if (logger.isErrorEnabled()) { logger.error("Error closing Elasticsearch client: ", ex); } } } }}
