java - 映射字符串arraylist获取键和值

从API响应中，我正在解析JSON

String myData = jsonSlurper.parseText(responseBody)
Map parsedBiblio = jsonSlurper.parseText(myData)

以下是parsedBiblio的输出

{"Data": {"AppNumber": "15671037", "CustomerNumber": "81744", "Date": "08-07-2017", "Status": "Active"},

 "Applicants": [{"Name": "abcd Inc.", "Address": "xxx, CA (US)"}],

下面是检索Data键和相应值的代码

Map<Object, Object> innerMap = parsedBiblio.get("Data")
for (Object objectName : innerMap.keySet()) {

       println("Key: " + objectName + " Value: "+ innerMap.get(objectName) +".");
 }

让我知道如何重新检索Applicants键和相应的值，因为这是map<string,List<string>格式，所以我将以以下格式声明内部映射

Map<String, List<String>> innerMapApplicant = parsedBiblio.get("Applicants")

我收到以下错误

 Cannot cast object '[{Address=xxx, CA (US), Name=abcd Inc.}]' with class 'java.util.ArrayList' to class 'java.util.Map' due to: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: java.util.Map(groovy.json.internal.LazyMap)

最佳答案

我认为您应该尝试按以下方式检索申​​请人：

List<Map<String,String>> applicantList =  = parsedBiblio.get("Applicants")

您可以按以下方式在地图中获取键和值：

  for(Map<String,String> applicantMap: applicantList)
  {
       for (Object objectName : applicantMap.keySet())
       {
          println("Key: " + objectName + " Value: "+ applicantMap.get(objectName) +".");
       }
   }
