我正在尝试一个简单的例子，通过连接Sping Boot 应用程序到elasticsearch数据库，我已经设置了如下配置

  1. @Configuration
  2. public class ElasticSearchConfig extends ElasticsearchConfiguration {
  3.     @Override
  4.     public ClientConfiguration clientConfiguration() {
  5.         return ClientConfiguration.builder()
  6.                 .connectedTo("localhost:9200")
  7.                 .build();
  8.     }
  9. }

字符串
Springboot版本：3.2.0

配置需要有ElasticSearch用户名和密码，以及CA SHA-256指纹
这解决了问题，现在它工作正常

  1. @Configuration
  2. public class ElasticSearchConfig extends ElasticsearchConfiguration {
  3.     @Override
  4.     public ClientConfiguration clientConfiguration() {
  5.         return ClientConfiguration.builder()
  6.                 .connectedTo("localhost:9200")
  7.                 .usingSsl("e0650a952ba6h5jb7d1ea9b3b8a59032j2005f675ec642jkg871038f27b2840d") //add the generated sha-256 fingerprint
  8.                 .withBasicAuth("elastic", "FnK9l206ZbUaI3kxzJKo") //add your username and password
  9.                 .build();
  10.     }
  11. }

字符串
这些数据可以在启动elasticsearch时找到，它会输出如下内容

  1. öüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöüΓöü
  2. ✅ Elasticsearch security features have been automatically configured!
  3. ✅ Authentication is enabled and cluster connections are encrypted.
  5. ℹ️  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  6.   FnK9l206ZbUaI3kxzJKo
  8. ℹ️  HTTP CA certificate SHA-256 fingerprint:
  9.   e0650a952ba6h5jb7d1ea9b3b8a59032j2005f675ec642jkg871038f27b2840d
