ES云托管在Azure中。它工作在春季数据ES 4.1.5(ES客户机7.9.3)中。但是spring数据ES 4.4.1 (ES客户端7.17.4)需要集群:monitor/main权限。

我的管理员不想批准这样的许可。

"root_cause":[{"type":"security_exception","reason":"action [cluster:monitor/main] is unauthorized for user [xxxx] with roles

我第一次问问题是在这篇文章里。Val指出/终结点集群级API需要此权限。why does it need cluster:monitor/main permission

我做了一些调试，并发现了更多的细节。在SimpleElasticsearchRepository初始化期间，Spring数据ES正在发送HEAD /和GET /。

对不起，我不能让格式正常工作。所以我在这里附上截图

在SimpleElasticsearchRepository初始化过程中出错。RestHighLevelClient

SimpleElasticsearchRepository -> RestIndexTemplate ->

在SimpleElasticsearchRepository初始化过程中，索引是空的。，因此对实际索引的正常HEAD请求变成了HEAD /。此用户帐户没有发送HEAD /的权限

既然目的是检查索引是否存在，那么如果索引为空，是否可以跳过与服务器的检查？因为它变成了检查集群级别信息的请求。以下的请求需要完全不同的许可。

头/头

头/actual_index

我也在日志中发现了这个错误。我不知道它是如何在春季数据中被发送出去的。这种使用也不能运行GET / .

它在春季数据ES 4.1.5中工作，为什么spring数据es4.1.5不发送到头/并得到/请求？

更新，包括我的原始帖子。

我发现了关于这些问题的细节。

HEAD /

在SimpleElasticsearchRepository初始化期间，它会执行以下操作。我的索引是createIndex = true。因此，它将检查是否存在()。但是索引在这里是空的，所以HEAD / my_index变成HEAD /。

我不知道为什么索引在这里是空的。但我将createIndex = false设为跳过它。

    if (this.shouldCreateIndexAndMapping() && !this.indexOperations.exists()) {
        this.indexOperations.createWithMapping();
    }

GET /

根据我的测试，GET /正在每个会话发送一次。它的作用就像网络连接性测试。如果有任何错误，它将被忽略。
