一、问题描述

SpringBoot 集成 Elasticsearch 时报错 Elasticsearch built-in security features are not enabled：

2022-03-25 18:23:50.589  WARN 58032 --- [/O dispatcher 1] org.elasticsearch.client.RestClient      : request [GET http://192.168.1.38:9200/] returned 1 warnings: [299 Elasticsearch-7.15.2-93d5a7f6192e8a1a12e154a2b81bf6fa7309da0c "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/7.15/security-minimal-setup.html to enable security."]

二、解决方法

在 elasticsearch.yml 配置 xpack.security.enabled 为 false，然后重启 Elasticsearch：

xpack.security.enabled: false
