Spring boot 弹簧靴&x2B；Hibernate搜索：已忽略必需的索引状态？

将HibernateSearch连接到Elasticsearch时，我注意到当我部署一个非HibernateSearch时，我的服务将无法成功连接。在我看来，设置所需索引状态的环境变量被忽略。我正在寻找一个打字错误或类似的半小时了，但找不到任何东西

环境变量：

$ kubectl describe pod <NAME>

Environment:

  SPRING_JPA_PROPERTIES_HIBERNATE_SEARCH_DEFAULT_ELASTICSEARCH_REQUIRED_INDEX_STATUS:  yellow

日志消息2：

我们可以清楚地看到它正在等待状态“绿色”而不是“黄色”。

我相信您的环境变量

SPRING\u JPA\u PROPERTIES\u HIBERNATE\u SEARCH\u DEFAULT\u ELASTICSEARCH\u REQUIRED\u INDEX\u status

正在被转换为

SPRING.JPA.PROPERTIES.HIBERNATE.SEARCH.DEFAULT.ELASTICSEARCH.REQUIRED.INDEX.status

，然而，它应该翻译成

spring.jpa.properties.hibernate.search.default.elasticsearch.required\u index\u status

（注意末尾的下划线）

我不知道Spring如何准确地翻译环境变量名，但必须有一种方法来转义下划线。也许是双下划线？您可能应该看看他们的文档

最糟糕的情况是，您可以将

spring.jpa.properties.hibernate.search.default.elasticsearch.required\u index\u status

设置为

application.properties

中的自定义环境变量，并设置该自定义环境变量，而不是您所做的操作。

我怀疑这也是一个问题，但我读过，因此认为它应该是正确的。我将尝试自定义环境变量，看看会发生什么，这样我们就有了更多的数据。您应该使用工件ID

hibernate search orm

，而不是

hibernate search

和2。您应该为

hibernate search orm

和

hibernate search elasticsearch

使用相同的版本。
