com.google.gson.JsonSyntaxException

Gson解析错误，不可以直接解析，用下面的方法即可

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result));
reader.setLenient(true);
BaseEntity<Entity, String> entity = gson.fromJson(reader, new TypeToken<BaseEntity<Entity, String>>() {}.getType());
return entity;
