【问题描述】：

我将 AWS elasticsearch 与休眠和 Spring MVC 结合使用。在服务器启动时自动检测elasticsearch的版本，抛出以下异常

Failed to detect the Elasticsearch version running on the cluster.

"message": "Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter. Authorization header requires 'SignedHeaders' parameter. Authorization header requires existence of either a 'X-Amz-Date' or a 'Date' header."

请注意，如果我使用专用的弹性搜索服务器安装而不是 AWS 弹性搜索服务，则一切正常。

【解决方案1】：

您可能在 elasticsearch 配置中设置以下属性

hibernate.search.default.elasticsearch.username hibernate.search.default.elasticsearch.password

AWS elasticsearch 服务默认使用匿名用户，因此不需要用户名密码。如果你设置了这些属性（即使是空白值）休眠将尝试使用基本身份验证来验证请求，这将失败，因为其他必需的标头将丢失。所以在使用 AWS elasticsearch 服务时不要设置以上属性。
