Bean定义:
1 public class GetM100DataResponse { 2 private String service;//接口代码 3 private String sessionId;//会话Id 4 private String errorCode;//错误码 5 private String errorMsg;//错误消息 6 private String summary;//摘要 7 8 private List<M100DataObject> dataPoints; //数据列表 9 10 //get set 略 11 }
1 public class M100DataObject { 2 private String dataType; //数据类型 String 3 private String sendDateTime; //发送时间 String 4 private M100DataObjectKV dataKV; //数值对象 Object 5 private String serviceNo; //用户服务号 String 6 private Integer userSeq; //用户序号 Integer 7 private String eqmtNo; //设备号 String 8 9 //get set 略 10 }
JSON字符串:
1 { 2 "dataPoints":[ 3 { 4 "dataKV":{ 5 "pulse":"103", 6 "measurementTime":"2015-12-02 12:06:32", 7 "low":"91", 8 "high":"126", 9 "id":"d750fed2-0c95-4722-92ac-3078fa34390b" 10 }, 11 "dataType":"1", 12 "eqmtNo":"", 13 "sendDateTime":"2015-12-02 12:06:33", 14 "serviceNo":"5716b0badb4b426cbfaaebb1be7d57b3", 15 "userSeq":"1" 16 } 17 ], 18 "diagResult":"", 19 "errorCode":"1", 20 "errorMsg":"成功!", 21 "propose":"", 22 "service":"GET_M100_DATA", 23 "sessionId":"1", 24 "summary":"" 25 }
转换代码如下:
1 public static JsonConfig getDecodeJSONConfig(){ 2 JsonConfig jsonConfig = new JsonConfig(); 3 jsonConfig.registerJsonValueProcessor(String.class, new JsonValueProcessor() { 4 public Object processArrayValue(Object value, 5 JsonConfig arg1) { 6 // TODO Auto-generated method stub 7 return process(value); 8 } 9 10 public Object processObjectValue(String key, 11 Object value, JsonConfig arg2) { 12 // TODO Auto-generated method stub 13 return process(value); 14 } 15 16 public Object process(Object value) { 17 try { 18 if (value instanceof String) { 19 return URLDecoder.decode(value.toString(),"UTF-8"); 20 } 21 return value == null ? "" : value.toString(); 22 } catch (Exception e) { 23 return ""; 24 } 25 } 26 } 27 ); 28 return jsonConfig; 29 } 30 public GetM100DataResponse parseData(String resData){//resData为JSON字符串 31 JsonConfig jsonConfig = getDecodeJSONConfig(); 32 JSONObject json = JSONObject.fromObject(resData, jsonConfig); 33 /* 34 * 在JSONObject.toBean的时候,如果转换的类中有集合, 35 * 可以先定义:Map<String, Class> classMap = new HashMap<String, Class>(); 36 * 然后在classMap中put你要转换的类中的集合名,如: 37 */ 38 Map<String, Class> classMap = new HashMap<String, Class>(); 39 classMap.put("dataPoints", M100DataObject.class);//dataPoints 为 属性名称 40 /* 41 * 然后在toBean()的时候把参数加上, 如: 42 */ 43 GetM100DataResponse response = (GetM100DataResponse)JSONObject.toBean(json, GetM100DataResponse.class, classMap); 44 return response; 45 }
