java - Jayway jsonpath 在正则表达式中以 "/"开头

Question

在使用包含 xpath 的正则表达式时，我遇到了 jayway jsonpath 的问题。这是我的 json:

{
  "status": "success",
  "resources": [
    {
      "id": "Attachment-20796b26-7a16-4a3d-b53c-b30d9f3cb798.TXT",
      "name": "1996032897__test1.CREDITPRINTFILE",
      "mimeType": "text/plain",
      "url": "https://test.com"
    }
  ]
}

这是我的表达:资源[?(/__test1.CREDITPRINTFILE/.test(@.name))]

我收到以下错误:

我也尝试在在线评估工具中使用相同的表达式:https://jsonpath.herokuapp.com/

Jayway - 给出相同的错误 - 预期路径节点加特林、Nebhale - 错误Goessner - 给了我有效的结果

我认为我正在使用最新版本的 jayway -

<dependency>
  <groupId>com.jayway.jsonpath</groupId>
  <artifactId>json-path</artifactId>
  <version>2.4.0</version>
</dependency>

问题:如果jayway不能解决这些表达式，是否有其他java库可以用来解决这些问题？

假设您正在查找“名称包含 __test1.CREDITPRINTFILE 的资源”，则 jsonpath 表达式 resources[?(@.name =~/.*__test1\.CREDITPRINTFILE/) ] 将与 Jayway 合作。测试于 https://jsonpath.herokuapp.com/
