Java
Java is terrible.
Jackson
Jackson is a java library for (de)serializing json.
If you create a JsonDeserializer
subclass that is an inner class of another class (like below), you need to mark that inner class as static
, or else you’ll get a $CLASS has no default (no arg) constructor
error.
public class Foo {
public static class FooDeserializer extends JsonDeserializer<Foo> {
@Override
public Foo deserialize(JsonParser parser, DeserializationContext ctx) throws IOException {
return null;
}
}
}
