java - 映射字符串数组列表获取键和值

Question

根据 API 响应，我正在解析 JSON

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

下面是 parsedBlio 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 的代码键和对应的值

Map<Object, Object> innerMap = parsedBiblio.get("Data")
for (Object objectName : innerMap.keySet()) {
   
       println("Key: " + objectName + " Value: "+ innerMap.get(objectName) +".");
 }

让我知道如何检索 Applicants键和相应的值，因为这是 map<string,List<string>格式，所以我将以下面的格式声明内部映射

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

我收到此错误

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)

我认为您应该尝试按如下方式检索申​​请人:

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

您可以按如下方式获取 map 中的键和值:

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