parse JSON with gson and GsonBuilder()
提问by senzacionale
String jsons = "{'appname':'application', 'Version':'0.1.0', 'UUID':'300V', 'WWXY':'310W', 'ABCD':'270B', 'YUDE':'280T'}";
This is my json string. How can i parse it to GsonBuilder() that i will get object back? I try few thinks but none works.
这是我的 json 字符串。我如何将它解析为 GsonBuilder() 以便我取回对象？我尝试很少思考，但没有任何效果。

public class YourObject {
private String appname;
private String Version;
private String UUID;
private String WWXY;
private String ABCD;
private String YUDE;
//getters/setters
}
parse to Object
解析为对象
YourObject parsed = new Gson().fromJson(jsons, YourObject.class);
or
或者
YourObject parsed = new GsonBuilder().create().fromJson(jsons, YourObject.class);
minor test
次要测试
String jsons = "{'appname':'application', 'Version':'0.1.0', 'UUID':'300V', 'WWXY':'310W', 'ABCD':'270B', 'YUDE':'280T'}";
YourObject parsed = new Gson().fromJson(jsons, YourObject.class);
works well
效果很好
EDIT
in this case use JsonParser
在这种情况下使用编辑JsonParser
JsonObject object = new JsonParser().parse(jsons).getAsJsonObject();
object.get("appname"); // application
object.get("Version"); // 0.1.0

JSON uses double quotes ("), not single ones, for strings so the JSON you have there is invalid. That's likely the cause of any issues you're having converting it to an object.
JSON"对字符串使用双引号 ( )，而不是单引号，因此您拥有的 JSON 无效。这可能是您将其转换为对象时出现任何问题的原因。
