  "lsp": [{
       "101": [{
            "value": "R36.0 lsp",

  }]
  "urm": [{
       "101": [{
            "value": "R36.0 urm",
            "revision": ["111","11br"]
        }]
        "202": [{
            "value": "R37.0 urm",
            "revision": ["111"]
        }]
        "301": [{
            "value": "R38.0 urm",
            "revision": ["222"]
        }]
    }]

   }]

  }

我想使用groovy打印/访问json文件中的值/修订字段，如果产品是（lsp和101），则比较它是否与我的输入匹配（“11br”，R36.0 lsp）。我只能到达101，后来我不知道如何提取更多的值。任何帮助表示赞赏

Answer 1

您可以使用JsonSlurper.parseText(json) - 它将生成一个地图地图，您可以遍历并提取有趣的值。在你的情况下，重要的是要提到你必须处理对象列表（通常它们只包含一个对象），因此遍历将产生列表列表等。在这种情况下，Groovy的.flatten()方法是很有帮助。请考虑以下脚本：

import groovy.json.JsonSlurper

def json = '''

def root = new JsonSlurper().parseText(json)
def lsp101 = root.Product.lsp.'101'.flatten()

def value = lsp101.value.first()
def revisions = lsp101.revision.flatten()

def expectedValue = 'R36.0 lsp'
def expectedRevision = '11br'

assert expectedValue == value && expectedRevision in revisions

它为路径value提取revisions和$.Product.lsp.101列表，并与预期值进行比较。希望它有助于理解如何在Groovy中使用JSON。有关更多信息和示例，请不要犹豫，访问详细介绍如何使用JSON的Groovy手册页 - http://groovy-lang.org/json.html
