是否可以使用Yamlslurper和YamlBuilder查找重复的属性名称？

如果我有这样的yaml文件：

obj:
  - name: 'msg'
    patterns:
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      '("cvv":")([^"]*)(")' : '$1xxxx$3'
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'

如果我使用groovy yamlslurper类来加载它，则“模式”对象将具有两个属性，其中包括以下名称：（

“ ssn”：“：”）（[^'^“）*）（[^'']*）（ ”）
（“ cvv”：“）（[^“^”]*）（“）

输入中的第三个属性具有与第一个属性名称相同的名称，因此第三个属性将覆盖第一个（或VICE反之亦然）。

有什么方法可以使用Yamlslurper或Yamlbuilder的某种组合来以某种方式检测到输入是否具有重复的属性名称？

我可以看到更改该文件的预期语法，以期期望这样的格式：

obj:
  - name: 'msg'
    patterns:
      - '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      - '("cvv":")([^"]*)(")' : '$1xxxx$3'
      - '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'

将使我能够检测重复。如果我无法使用原始格式在输入上检测重复的属性名称，则将考虑更改规格以需要修改格式。

If I have a yaml file like this:

obj:
  - name: 'msg'
    patterns:
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      '("cvv":")([^"]*)(")' : '$1xxxx$3'
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'

If I use the Groovy YamlSlurper class to load this, the "patterns" object will have two properties, with the following names:

("ssn":")([^"]*)(")
("cvv":")([^"]*)(")

The third property in the input has a name identical to the first property name, so the third one will override the first (or vice versa).

Is there any way I could use some combination of YamlSlurper and perhaps YamlBuilder to somehow detect that the input has a duplicate property name?

I can see that changing the expected syntax of this file so that it expects a format like this:

obj:
  - name: 'msg'
    patterns:
      - '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      - '("cvv":")([^"]*)(")' : '$1xxxx$3'
      - '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'

Would give me the ability to detect duplicates. If I can't detect duplicate property names on the input using the original format, I will consider changing the spec to require the modified format.

Groovy.yaml.yamlslurper有一个Jackson库。

yamlslurper.parse（）
- ＆gt; yamlconverter.convertyamltojson（） - ＆gt; Jackson

因此，您可以使用它来检测首先重复：

import com.fasterxml.jackson.dataformat.yaml.YAMLFactory
import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.databind.DeserializationFeature

String yaml = '''
obj:
  - name: 'msg'
    patterns:
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      '("cvv":")([^"]*)(")' : '$1xxxx$3'
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
'''

def result =
    new ObjectMapper()
        .enable(DeserializationFeature.FAIL_ON_READING_DUP_TREE_KEY)
        .readTree(new YAMLFactory().createParser(yaml))

此代码引发异常：

com.fasterxml.jackson.databind.exc.MismatchedInputException: 
  Duplicate field '("ssn":")([^"]*)(")' for `ObjectNode`: 
  not allowed when `DeserializationFeature.FAIL_ON_READING_DUP_TREE_KEY` enabled
  at [Source: (StringReader); line: 7, column: 31]

behind groovy.yaml.YamlSlurper there is a jackson library.

YamlSlurper.parse()
-> YamlConverter.convertYamlToJson() -> jackson

so, you could use it to detect first duplicate:

import com.fasterxml.jackson.dataformat.yaml.YAMLFactory
import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.databind.DeserializationFeature

String yaml = '''
obj:
  - name: 'msg'
    patterns:
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
      '("cvv":")([^"]*)(")' : '$1xxxx$3'
      '("ssn":")([^"]*)(")' : '$1xxxxxxxxx$3'
'''

def result =
    new ObjectMapper()
        .enable(DeserializationFeature.FAIL_ON_READING_DUP_TREE_KEY)
        .readTree(new YAMLFactory().createParser(yaml))

this code throws exception:

com.fasterxml.jackson.databind.exc.MismatchedInputException: 
  Duplicate field '("ssn":")([^"]*)(")' for `ObjectNode`: 
  not allowed when `DeserializationFeature.FAIL_ON_READING_DUP_TREE_KEY` enabled
  at [Source: (StringReader); line: 7, column: 31]
