我想將 json 字符串解析為 JSONObject 但符號“：”似乎解析錯誤例如 ->"time": "2019-05-28T16:30:29Z"會出錯但是改成"time": "20190526"就OK了這是整個 json 對象：{ "channel": 922875000, "sf": 12, "time": "2019-05-28T16:30:29Z", "gwip": "192.168.0.180", "gwid": "00001c497b431ff5", "repeater": "00000000ffffffff", "systype": 170, "rssi": -103, "snr": 20.5, "snr_max": 33, "snr_min": 18, "macAddr": "00000000aabb60ba", "data": "00000000", "frameCnt": 8, "fport": 3}和解析代碼： try { JSONObject sensorObject = new JSONObject(message.toString()); SensorModel sensorModel = new Gson().fromJson(sensorObject.toString(), SensorModel.class); } catch (JSONException e) { logger.error(e.getMessage()); }我怎樣才能讓他保持相同的"2019:05:26"內容？

使用ObjectMapper如下：

public class JSONObject {

private double snr_min;
private double snr_max;
private String macAddr;
private String data;
private int frameCnt;
private int fport;
public int getChannel() {
return channel;
}
public void setChannel(int channel) {
this.channel = channel;
}
public int getSf() {
return sf;
}
public void setSf(int sf) {
this.sf = sf;
}
public Date getTime() {

public void setSystype(int systype) {

}
public int getRssi() {

}
public void setRssi(int rssi) {
this.rssi = rssi;
}
public double getSnr() {

}
public double getSnr_min() {

}
public double getSnr_max() {

}

}
public String getMacAddr() {

}
public void setMacAddr(String macAddr) {

}
public static void main(String[] args) throws Exception {
String json = "{\"channel\":922875000,\"sf\":12,\"time\":\"2019-05-28T16:30:29Z\",\"gwip\":\"192.168.0.180\",\"gwid\":\"00001c497b431ff5\",\"repeater\":\"00000000ffffffff\",\"systype\":170,\"rssi\":-103,\"snr\":20.5,\"snr_max\":33,\"snr_min\":18,\"macAddr\":\"00000000aabb60ba\",\"data\":\"00000000\",\"frameCnt\":8,\"fport\":3}";
ObjectMapper objectMapper = new ObjectMapper();
JSONObject obj = objectMapper.readValue(json, JSONObject.class);
System.out.println(obj.toString());
}
