一般的json解析工具都是解析一层或两层的，多层的不容易兼容
json格式
{
"ANSWERS": [
{
"ANS_MSG_HDR": {
"MSG_CODE":"0", //返回程序执行正确或者错误的编码
"MSG_TEXT":"", //返回程序执行正确或者错误的信息
"MSG_LEVEL":"",
"RESULT_NUM":"2",
"MSG_ID":"",
"PACKAGE_FLAG":"0",
"DATA_ROWS":"1",
"BPM_ROWS":"0",
"RUN_TIMES":"50", //运行时间
"MSG_TRACE":""
},
"ANS_COMM_DATA": //返回的主要数据
[
{
"ACTL_ISSUE_SIZE": "3.2915",
"INVEST_CONSU": "",
"FEE_CALC_MODE":"",
"PROD_DESC":"啦啦啦",
"PROD_NAME":"啦啦啦",
"NEWEST_NET_VAL": "1.151",
"RISK_TYPE":"2",
"SELL_STATUS": "2",
"FEE_RATE_FEE_CEIL": "",
"ISSUE_PERSON_DES": "啦啦啦",
……..
}
],
{
"BPM_DATA": [ ]
},
{
"CONFIG": { }
}

}
]
}
利用fastjson的parseObject解析后自己组装
public static CommonResponse<ANSWERS> convertFromJsonString(String json)
{ CommonResponse<ANSWERS> response = new CommonResponse<ANSWERS>(); JSONObject jsonObj = JSONObject.parseObject(json); JSONArray jsonArray = (JSONArray)jsonObj.get("ANSWERS"); List<ANSWERS> ansList = new ArrayList<ANSWERS>(); for (int i = 0; i < jsonArray.size(); i++ ) { ANSWERS answer = new ANSWERS(); JSONObject innerJsonObj = (JSONObject)jsonArray.get(i); JSONObject hdrJsonObj = (JSONObject)innerJsonObj.get("ANS_MSG_HDR"); ANS_MSG_HDR hdrObj = JSONObject.parseObject(hdrJsonObj.toJSONString(), ANS_MSG_HDR.class); JSONArray bodyJsonArray = (JSONArray)innerJsonObj.get("ANS_COMM_DATA"); List<Object> bodyList = new ArrayList<Object>(); JSONArray aTumArray = (JSONArray)bodyJsonArray.get(0); List<ANS_COMM_DATA> aTumList = new ArrayList<ANS_COMM_DATA>(); for (int j = 0; j < aTumArray.size(); j++ ) { JSONObject aTumJsonObj = (JSONObject)aTumArray.get(j); ANS_COMM_DATA aTumObj = JSONObject.parseObject(aTumJsonObj.toJSONString(), ANS_COMM_DATA.class); aTumList.add(aTumObj); } bodyList.add(aTumList); JSONObject bpmData = (JSONObject)bodyJsonArray.get(1); JSONObject configData = (JSONObject)bodyJsonArray.get(2); bodyList.add(bpmData); bodyList.add(configData); answer.setANS_COMM_DATA(bodyList); answer.setANS_MSG_HDR(hdrObj); ansList.add(answer); } response.setANSWERS(ansList); return response; }
