如果你沒有關於什麼的響應將包含確切的知識,您可以隨時使用地圖類的實現傳授給GSON,因爲我試圖在這裏證明:
public class RestResponse {
private boolean success;
private String errorDescription;
private Map<String, Object> data;
private static Gson GSON = new Gson();
private RestResponse()
{
data = new HashMap<String, Object>();
}
public boolean isSuccess() {
return success;
}
private void setSuccess(boolean success) {
this.success = success;
}
public String getErrorDescription() {
return errorDescription;
}
private void setErrorDescription(String errorDescription) {
this.errorDescription = errorDescription;
}
public Object getData(String... nestedKeys)
{
List<String> nestedKeysAsList = Arrays.asList(nestedKeys);
return getData(nestedKeysAsList);
}
public Object getData(List<String> nestedKeys)
{
String firstKey = nestedKeys.get(0);
if(!data.containsKey(firstKey))
throw new IllegalArgumentException("Key not found");
Object mapValue = data.get(firstKey);
if(!(mapValue instanceof Map))
return mapValue;
String finalKey = nestedKeys.get(nestedKeys.size()-1);
if(nestedKeys.size() > 2)
{
for(String nextKey : nestedKeys.subList(1,nestedKeys.size()-1))
{
Map<String,Object> tempMap = (Map)mapValue;
mapValue = tempMap.get(nextKey);
}
}
Map<String,Object> tempMap = (Map)mapValue;
return tempMap.get(finalKey);
}
private Map<String, Object> getData() {
return data;
}
private void setData(Map<String, Object> map){
this.data = map;
}
public static RestResponse createUnsuccessfulResponse(Exception e)
{
return createUnsuccessfulResponse(e.getMessage());
}
public static RestResponse createUnsuccessfulResponse(String reason)
{
RestResponse res = new RestResponse();
res.setSuccess(false);
res.setErrorDescription(reason);
return res;
}
public static RestResponse createSuccessfulResponse(String jsonString)
{
Map<String, Object> jsonToDataMap = GSON.fromJson(jsonString, Map.class);
return createSuccessfulResponseByMap(jsonToDataMap);
}
private static RestResponse createSuccessfulResponseByMap(Map<String, Object> jsonToDataMap)
{
RestResponse res = new RestResponse();
res.setSuccess(true);
res.setErrorDescription("Success");
res.setData(jsonToDataMap);
return res;
}
}

你可以遵循的形式給出了對bean的格式,這樣的bean包含的所有元素(那些可以發現或不能在JSON源泉)還你讀它json有很多參數,所以它的bette你使用bean'http://www.jsoneditoronline.org/?id = 13e7c95e8439b49c20412204ecaa1c8e' – Divya 2014-10-18 17:33:34
