如何解析Json字符串中的符号“：”

Question

我想将 json 字符串解析为 JSONObject 但符号“：”似乎解析错误

例如 ->"time": "2019-05-28T16:30:29Z"会出错

但是改成"time": "20190526"就OK了

这是整个 json 对象：

{

    "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

}

和解析代码：

    try {

        JSONObject sensorObject = new JSONObject(message.toString());

        SensorModel sensorModel = new Gson().fromJson(sensorObject.toString(), SensorModel.class);

    } catch (JSONException e) {

        logger.error(e.getMessage());

    }

我怎样才能让他保持相同的"2019:05:26"内容？

使用ObjectMapper如下：import com.fasterxml.jackson.databind.ObjectMapper;import java.util.Date;public class JSONObject {    private int channel;    private int sf;    private Date time;    private String gwip;    private String gwid;    private String repeater;    private int systype;    private int rssi;    private double snr;    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() {        return time;    }    public void setTime(Date time) {        this.time = time;    }    public String getGwip() {        return gwip;    }    public void setGwip(String gwip) {        this.gwip = gwip;    }    public String getGwid() {        return gwid;    }    public void setGwid(String gwid) {        this.gwid = gwid;    }    public String getRepeater() {        return repeater;    }    public void setRepeater(String repeater) {        this.repeater = repeater;    }    public int getSystype() {        return systype;    }    public void setSystype(int systype) {        this.systype = systype;    }    public int getRssi() {        return rssi;    }    public void setRssi(int rssi) {        this.rssi = rssi;    }    public double getSnr() {        return snr;    }    public void setSnr(double snr) {        this.snr = snr;    }    public double getSnr_min() {        return snr_min;    }    public void setSnr_min(double snr_min) {        this.snr_min = snr_min;    }    public double getSnr_max() {        return snr_max;    }    public void setSnr_max(double snr_max) {        this.snr_max = snr_max;    }    public String getMacAddr() {        return macAddr;    }    public void setMacAddr(String macAddr) {        this.macAddr = macAddr;    }    public String getData() {        return data;    }    public void setData(String data) {        this.data = data;    }    public int getFrameCnt() {        return frameCnt;    }    public void setFrameCnt(int frameCnt) {        this.frameCnt = frameCnt;    }    public int getFport() {        return fport;    }    public void setFport(int fport) {        this.fport = fport;    }    @Override    public String toString() {        return "JSONObject{" + "channel=" + channel + ", sf=" + sf + ", time=" + time + ", gwip=" + gwip + ", gwid=" + gwid + ", repeater=" + repeater + ", systype=" + systype + ", rssi=" + rssi + ", snr=" + snr + ", snr_min=" + snr_min + ", snr_max=" + snr_max + ", macAddr=" + macAddr + ", data=" + data + ", frameCnt=" + frameCnt + ", fport=" + fport + '}';    }    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());    }}
