有人有Deserializer工作吗？我在方法“deserialize”而不是元素中获得完整的
JSON表达式？
public static void main(String[] args) {
GsonBuilder gb = new GsonBuilder();
gb.registerTypeAdapter(DummyObject.class,new JsonSerializer<Date>() {
public JsonElement serialize(Date src,Type typeOfSrc,JsonSerializationContext context) {
System.out.println("serialize...");
return new JsonPrimitive(DateUtil.toString(src));
}
});
gb.registerTypeAdapter(DummyObject.class,new JsonDeserializer<Date>() {
DateFormat format = DateFormat.getInstance();
public Date deserialize(JsonElement json,Type typeOfT,JsonDeserializationContext context) throws JsonParseException {
if (!(json instanceof JsonPrimitive)) {
throw new JsonParseException("The date should be a string value");
}
try {
return format.parse(json.getAsString());
} catch (ParseException e) {
throw new JsonParseException(e);
}
}
});
String jsonExp = "{\"createdDate\":\"2011-12-27T15:21:16\"}";
Gson g = gb.create();
DummyObject tf = g.fromJson(jsonExp,DummyObject.class);
}
解决方法
Gson gson = new GsonBuilder()
.setDateFormat("yyyy-MM-dd'T'HH:mm:ssz")
.create();
