I have my json file and corresponding java bean classes.
JSON file has multiple records,So i have LIST of objects,where i am facing the problem.LIST is not being populated.
JSON file:
{"RequestServices":
{`enter code here`
"RequestService":
[
{
"orderNumber":456,
"organizationId":123,
"headerId":3446
}
]
}
}
JAVA CLASSES:
public class RequestServices {
private List<RequestService> requestServices=new ArrayList<RequestService>();//array of objects
//default getter,setter of List<RequestService>
}
-----
public class RequestService {
private String orderNumber;
private String organizationId;
private String headerId;
/* setters and getters */}
-----
Main.class
public class JSONBind {
public static void main(String[] args) {
Gson gson = new Gson();
try {
BufferedReader br = new BufferedReader(new fileReader("c:\\JSON1.json"));
//convert the json string back to object
RequestServices obj = gson.fromJson(br, RequestServices.class);
的System.out.println(obj.getRequestServices()得到(0).getOrderNumber()); //獲取錯誤 }}} 當我嘗試打印對象列表(即REquestService),它給出IndexOutofBound 在此先感謝,Waitin爲您提供幫助!JSON到Java對象使用GSON多個記錄
非常感謝,我將變量名改爲與json文件完全相同,現在它的工作正常, – user1570345 2015-04-01 05:00:43
但是,我們可以將json值映射到GSON中的java對象變量名嗎? – user1570345 2015-04-01 05:01:28
很高興爲您服務!當它解決了問題時,你可以請,接受答案?關於你的問題我不明白,你能解釋一下嗎? – 2015-04-01 05:03:11
