Java RestHighLevelClient - 弹性搜索 - 如何在 id 字段值中添加特殊字符“/”

编程问答 2022-05-15

问题描述

在弹性搜索中插入带有“/”的字段值时出现异常

代码：

String id = "/EACVBSDSFASFA";

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

异常：

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

解决方法

问题不是因为字段，而是因为您使用 / 作为 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 - 首选网址安全 ID，例如：
