es使用遇到的bug总结

本文主要是介绍es使用遇到的bug总结，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

本来版本7.4.0不行，最后换了个版本7.15.1就可以了，但又出现以下问题了：

@Beanpublic ElasticsearchClient elasticsearchClient() {
//        RestClient client = RestClient.builder(new HttpHost("localhost", 9200,"http")).build();RestClient client = RestClient.builder(new HttpHost("192.168.101.128", 9200, "http")).setDefaultHeaders(new Header[]{new BasicHeader("Content-type", "application/json"),new BasicHeader("X-Elastic-Product", "Elasticsearch")}).build();ElasticsearchTransport transport = new RestClientTransport(client, new JacksonJsonpMapper());return new ElasticsearchClient(transport);}

"Elasticsearch built-in security features are not enabled. Without authentication, your cluster could be accessible to anyone. See https://www.elastic.co/guide/en/elasticsearch/reference/7.13/security-minimal-setup.html to enable security."  

elasticsearch.yml配置：xpack.security.enabled: false 

这篇关于es使用遇到的bug总结的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
