放心的GPATH表达方式是什么

发布于 2025-02-09 01:02:07 字数 1348 浏览 3 评论 0原文

我试图使用过滤条件创建GPATH表达式，以返回“ mynotes”在'“ my-type”'''

'''data.my-node.nodes时。 findall {it.'my-type'=='常规'}。'my-nodes'''''

但无法从下面的json获得响应

{
   "data": {"my-node":    [
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "abcdefg"}],
            "my-type": "GENERAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "abcdefg"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "oiugitoirtuhou"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "ifuoirjhihj"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "idfgdiufgdhsfuihdf"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "iydfgsigdfgdgidsf"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      }
   ]}
}

原文

I have tried to create GPath expression with filter criteria to return "my-notes" in list of object when '"my-type"' is SPECIAL

like : '"data.my-node.nodes.findAll{it.'my-type'=='GENERAL'}.'my-nodes'"'

but unable to get response from the below json

{
   "data": {"my-node":    [
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "abcdefg"}],
            "my-type": "GENERAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "abcdefg"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "oiugitoirtuhou"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "ifuoirjhihj"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "idfgdiufgdhsfuihdf"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      },
            {
         "nodes": [         {
            "my-nodes": [{"my-note": "iydfgsigdfgdgidsf"}],
            "my-type": "SPECIAL"
         }],
         "my-instruction": null
      }
   ]}
}

GPATH语法是

List<?> value = JsonPath.from(res).get("data['my-node'].nodes.flatten().findAll{it.'my-type'=='GENERAL'}['my-nodes'].flatten()");
System.out.println(value);
//[{my-note=abcdefg}]

首先，使用['key-abc']对键包含特殊字符。
其次，使用flatten（）方法将2D数组制成1D数组。

The GPath syntax is

List<?> value = JsonPath.from(res).get("data['my-node'].nodes.flatten().findAll{it.'my-type'=='GENERAL'}['my-nodes'].flatten()");
System.out.println(value);
//[{my-note=abcdefg}]
