将groovy映射的键值对转换为JSON数组元素

Question

如何获取groovy映射的键/值对值并循环到groovyJSON数组元素中？。

例如：

输入：

def childmap = ["data1": "123 "，" data2": "234 "，" data3": "456"]

def儿童地图2=["data4"："123"，"data5"："234"，"data6"："456"，"date7"："676"]

def父母地图=["Key1"："Value1"，"Key2"："Value2"，"Key3"：儿童地图，"key 4"：儿童地图2]

预期JSON输出：

{
 "Json":{
   "Key1":"Value1",
   "Key2":"Value2"
   "key3":[
      {
         "Name": "data1",
         "ID": "123"
      },
      {
         "Name": "data2",
         "ID": "234"
      },
      {
          "Name": "data3",
          "ID": "456"
      }
   ],
  "key4":[
      {
         "Name": "data4",
         "ID": "123"
      },
      {
         "Name": "data5",
         "ID": "123"
      },
      {
         "Name": "data6",
         "ID": "234"
      },
      {
          "Name": "data7",
          "ID": "456"
      }
   ]
}

}

这适用于您的示例。如果你有更深的嵌套，这是行不通的。

def newmap = parentmap.collectEntries { key, value ->
    [key, (value instanceof Map) ? value.collect {key2, value2 -> [Name: key2, ID: value2]} : value]}


def builder = new JsonBuilder([Json : newmap])
println builder.toPrettyString()
