ObjectMapper - Desserialize flattened object
I have the following class that uses internally a HashMap:
open class I18n<T> {
var i18n: MutableMap<LanguageEnum, T?> = mutableMapOf()
@JsonAnyGetter get
fun add(lang: LanguageEnum, value: T?) {
i18n[lang] = value
}
// ...
}
Thanks to the @JsonAnyGetter annotation, when I serialize this into Json I have the following format:
{
"pt": "Texto exemplo",
"en": "Example text"
}
instead of
{
i18n: {
"pt": "Texto exemplo",
"en": "Example text"
}
}
Now I need to make the way back. I have a HashMap containing the languages key and I need to desserialize it into my I18n object.
The caveat here is that I'm doing this among a lot of reflections and abstractions and it would be really nice if it could work like this:
// Here I am going through the fields of a given POJO.
// One of those fields is a I18n type.
// My model variable is a Map containing the same keys as my POJO field's name, so I'm basically trying to map them all
for (f in fields) {
if (model.containsKey(f.name)) {
// when f.type is I18n, value is a HashMap<string, string>
val value = model[f.name]
f.isAccessible = true
// when f.type is I18n.class, the field is set to an empty instance of I18n because it could not desserialize
f.set(dto, mapper.convertValue(value, f.type))
f.isAccessible = false
}
}
I would not like to do things like:
if (f.type === I18n.class) {
// Special treatment
}
Any ideas? Thanks in advance.
