Question

我有一个JSON字符串，我使用mapper.readValue()

转换为数据对象

我要转换的JSON字符串是：

[  
  {  
    "id":79107417,
    "email":"xxx@gmail.com",
    "optInType":"Single",
    "emailType":"Html",

        "value":null

      {  
        "key":"TITLE",
        "value":null
      },
      {  
        "key":"VINATONDONIABOUGHT",
        "value":null
      },
      {  
        "key":"WINE-NAME",
        "value":null
      }
    ],
    "status":"Subscribed"
  }
]

这是我的代码：

String jsin = "{\"dotMailerContact\":" + result.toString() + "}";
JSONObject jo = new JSONObject(jsin);
ObjectMapper mapper = new ObjectMapper();
StringReader reader = new StringReader(jo.toString()); // Json
// LASTSUBSCRIBED
MainDotMailerResponse moduleDto = mapper.readValue(reader, MainDotMailerResponse.class);
for (DotMailerContact dot: moduleDto.getDotMailerContact()) {
 ArrayList < LinkedHashMap < String, String >> dataFields = dot.getDataFields();
 for (Map < String, String > map: dataFields) {

  for (String key: map.keySet()) {
   System.out.println("key: " + key + " value " + String.valueOf(map.get(key)));
  }
 }
}

转换id，email等属性是有效的，但dataFields数组条目的转换方式错误（值，键）：

[{value=0.0, key=ABV}, {value=null, key=ACCOUNTNUMBER}, {value=null, key=ACELLARING}, {value=null, key=ACOLREDWINE}, {value=null, key=ACOLWHITEWINE}, {value=null, key=ADRINKING}, {value=null, key=AENPRIMEUR}, {value=null, key=AGIFTS}, {value=null, key=AHASIBSTORAGE}, {value=null, key=AINTERESTEDINRESALE}, {value=FINE+RARE, key=AM_FROM_NAME}, {value=FINE+RARE, key=AM_NAME}, {value=null, key=AOV}, {value=null, key=AREGBORDEAUX}, {value=null, key=AREGCHAMPAGNE}, {value=null, key=AREGFORTIFIEDS}, {value=null, key=AREGITALY}, {value=null, key=AREGNEWWORLD}, {value=null, key=AREGREDBURGUNDY}, {value=null, key=AREGRHONE}, {value=null, key=AREGSPAIN}, {value=null, key=AREGSPIRITS}, {value=null, key=AREGUSA}, {value=null, key=AREGWHITEBURGUNDY}, {value=null, key=AROSE}, {value=null, key=BLOCKBUSTER}, {value=null, key=COMPANYNAME}, {value=7.740008599E9, key=CONTACTNUMBER}, {value=France, key=COUNTRY}, {value=44, key=COUNTRYCODE}, {value=null, key=DELIVERY-DATE}, {value=null, key=DELIVERY-TIME}, {value=null, key=DIRECT-SIGN-UP}, {value=Chloe, key=FIRSTNAME}, {value=, key=FULLNAME}, {value=null, key=GENDER}, {value=Ashton, key=LASTNAME}, {value=null, key=LASTSIDATE}, {value=2017-11-16T08:47:45, key=LASTSUBSCRIBED}, {value=null, key=M-B-REGION-VOL-NAME}, {value=null, key=M-B-VINT-VOLUME-NAME}, {value=null, key=M-B-WINE-VOLUME-NAME}, {value=null, key=MOST-ACTIVE-MONTH}, {value=null, key=NOTBLOCKBUSTER}, {value=null, key=POSTCODE}, {value=true, key=PRIVACYAGREEMENT}, {value=null, key=REFERREDBY}, {value=null, key=SALESORDERS}, {value=null, key=STORAGE-NUMBER}, {value=null, key=TITLE}, {value=null, key=VINATONDONIABOUGHT}, {value=null, key=WINE-NAME}]

你能帮忙吗，我在这里做错了什么？
