[当我尝试使用Gson库反序列化对象的JSON数组时遇到问题。
JSON数组的示例:
[
{"ID":1,"Title":"Lion","Description":"bla bla","ImageURL":"http:\/\/localhost\/lion.jpg"},
{"ID":1,"Title":"Tiger","Description":"bla bla","ImageURL":"http:\/\/localhost\/tiger.jpg"}
]
您怎么看?反序列化此类JSON响应的正确Java代码是什么?
要反序列化JSONArray,您需要使用TypeToken。您可以从GSON user guide了解更多信息。示例代码:
@Test
public void JSON() {
Gson gson = new Gson();
Type listType = new TypeToken<List<MyObject>>(){}.getType();
// In this test code i just shove the JSON here as string.
List<Asd> asd = gson.fromJson("[{'name':\"test1\"}, {'name':\"test2\"}]", listType);
}
如果您有JSONArray,则可以使用
...
JSONArray jsonArray = ...
gson.fromJson(jsonArray.toString(), listType);
...
