java - Android. Setting default value for invalid json field

Question

I am using retrofit and json converter. I create POJO which contains some fields. One of these fields should be int, but if the server sends something else instead of int, I need to write the default value in this field, for example 2. Now if the server sends something other than int, I get an exception (json malformed exception) in my request, since in the POJO the field is declared as int. Is it possible to write a default value in this field if the server sends something other than int.

如果服务器向您发送 null ，您可以使用 Int 来存储该值，否则解析将不会成功；另一方面，如果您需要除 null 以外的其他值作为默认值，您可以覆盖您的 set 或 get 方法；set to if is null 将值设置为零或 get 如果值为 null 返回 0。

希望它有助于调试您的问题，如果服务器向您发送多个值，如字符串、布尔值等。您应该讨论哪个值是您需要的值。
