在弹性搜索中使用“/”插入字段值时出现异常

代码：

String id = "/EACVBSDSFASFA";

IndexRequest indexRequest = new IndexRequest(INDEX, TYPE, id).source(objectsMap);
                    IndexResponse indexResponse = restHighLevelClient.index(indexRequest, RequestOptions.DEFAULT);

例外：

Path part [/EACVBSDSFASFA] couldn't be encoded: java.lang.IllegalArgumentException

问题不是因为该字段，而是因为您将/其用作 id 的一部分。

我猜这是一个限制，以防止必须对 ID 进行编码的资源，例如 http://localhost:9200/index/_type/%2FEACVBSDSFASFA，注意/->%2F转换。

在任何情况下 - 更喜欢 url 安全的 ID，例如：
