Is it possible to serialize object to JSON using toString method without custom serializer?
I have this class:
public class JsonUser {
private final String id;
private final String email;
public JsonUser(String id, String email) {
this.id = id;
this.email = email;
}
@Override
public String toString() {
JsonObject json = new JsonObject();
json.addProperty("id", user.id());
json.addProperty("email", user.email());
return json.toString();
}
}
As you see, JsonUser::toString returns a JSON string. I'm wondering if there is any way to tell Jackson to serialize JsonUser by calling toString method, instead of by fields/properties.
Is it possible to achieve that without using @JsonSerialize with a custom serializer?

I think if you annotate thetoString()method with@JsonValuethat Jackson will use that for serialization. Similarly, you can annotate a String constructor with@JsonCreatorfor deserialization.

I think if you annotate thetoString()method with@JsonValuethat Jackson will use that for serialization. Similarly, you can annotate a String constructor with@JsonCreatorfor deserialization.
