Question

json转换为javabean报错。A JSONObject text must begin with '{' at character 0 of

这是str输出{"address":"33","conTel":"","desc":"","email":"","eptCarports":498,"freeTime":0,"inEntranceNum":0,"isCharge":1,"latitude":"23.04715","longitude":"113.102868","outEntraceNum":0,"parkCode":"2KPI5T73","parkName":"对外调试停车场","totalCarports":999}

使用str数据，把json转换为javabean去存到数据库中报错
for (String str : proStr) {
System.out.println(str);
ParkInfo park = (ParkInfo) JSONObject.toBean(JSONObject.fromObject(str), ParkInfo.class);
System.out.println(park);
ParkInfo PA = this.parkepository.save(park);

}

Answer 1

出现这个异常的原因是json串格式不正常，没有"{"开始或没有"}"结尾
将你的数据和代码放到程序中是可以运行的，应该还是数据的问题
import net.sf.json.JSONObject;

public class ParkInfoService {

public static void main(String[] args) {
String str = "{\"address\":\"33\",\"conTel\":\"\",\"desc\":\"\",\"email\":\"\",\"eptCarports\":498,\"freeTime\":0,\"inEntranceNum\":0,\"isCharge\":1,\"latitude\":\"23.04715\",\"longitude\":\"113.102868\",\"outEntraceNum\":0,\"parkCode\":\"2KPI5T73\",\"parkName\":\"对外调试停车场\",\"totalCarports\":999}";
System.out.println(str);
ParkInfo park = (ParkInfo) JSONObject.toBean(JSONObject.fromObject(str), ParkInfo.class);
System.out.println(park.toString());
}

}

追问

{"data":{"address":"33","conTel":"","desc":"","email":"","eptCarports":498,"freeTime":0,"inEntranceNum":0,"isCharge":1,"latitude":"23.04715","longitude":"113.102868","outEntraceNum":0,"parkCode":"2KPI5T73","parkName":"对外调试停车场","totalCarports":999},"message":"业务成功","resultCode":0,"status":1}

这是完整的数据

我对这个数据进行切分

String[] proStr = parkstr.split("\\{\"data\":|,\"message\":\"业务成功\",\"resultCode\":0,\"status\":1}|\\)");

就切分成了{"address":"33","conTel":"","desc":"","email":"","eptCarports":498,"freeTime":0,"inEntranceNum":0,"isCharge":1,"latitude":"23.04715","longitude":"113.102868","outEntraceNum":0,"parkCode":"2KPI5T73","parkName":"对外调试停车场","totalCarports":999}

追答

可以把parkstr输出的值发我下吗

追问

value = {"data":{"address":"33","conTel":"","desc":"","email":"","eptCarports":498,"freeTime":0,"inEntranceNum":0,"isCharge":1,"latitude":"23.04715","longitude":"113.102868","outEntraceNum":0,"parkCode":"2KPI5T73","parkName":"对外调试停车场","totalCarports":999},"message":"业务成功","resultCode":0,"status":1}

没有vlue=

追答

可能你切分的时候破坏了json数据原本的格式。
那咱就换种方法来写，代码如下：
还有个实体，但是已经超出最大字数限制了，你私信我，我发你
逻辑：
import net.sf.json.JSONObject;
public class ParkInfoService {
public static void main(String[] args) {
String value = "{\"data\":{\"address\":\"33\",\"conTel\":\"\",\"desc\":\"\",\"email\":\"\",\"eptCarports\":498,\"freeTime\":0,\"inEntranceNum\":0,\"isCharge\":1,\"latitude\":\"23.04715\",\"longitude\":\"113.102868\",\"outEntraceNum\":0,\"parkCode\":\"2KPI5T73\",\"parkName\":\"对外调试停车场\",\"totalCarports\":999},\"message\":\"业务成功\",\"resultCode\":0,\"status\":1}";
ResponseRetu responseRetu = (ResponseRetu)JSONObject.toBean(JSONObject.fromObject(value),ResponseRetu.class);
ParkInfo parkInfo = responseRetu.getData();
System.out.println(parkInfo);
}
}

Answer 2

是不是str前后有多余的空格之类的，改成这个试试JSONObject.fromObject(str.trim())

追问

{"data":{"address":"33","conTel":"","desc":"","email":"","eptCarports":498,"freeTime":0,"inEntranceNum":0,"isCharge":1,"latitude":"23.04715","longitude":"113.102868","outEntraceNum":0,"parkCode":"2KPI5T73","parkName":"对外调试停车场","totalCarports":999},"message":"业务成功","resultCode":0,"status":1}这是原来的数据，我把他切分了，不可能有空的地方的吧
