Add extension to force generated classes to implement additional interface(s)

It may be convenient to ask generator to place super class (or interface) reference into generated DTO, for instance

Schema
{
...
"javaType":"model.json.Buffer",
"javaSuper":"model.AbstractModel",
"javaInterfaces": ["java.io.Serializable","api.CustomContract"],
"properties":{
"id":{
"type":"integer",
"id":"id"
},
"title":{
"type":"string",
"id":"title"
}
...
"type":"object"
}

Generated
...
public class Buffer extends AbtractModel implements Serializable, CustomContract {
private int id;
private String title;
...

It may also generate stub implementations of interface methods automatically if any.

If you have the super class on the classpath you should be able to achieve javaSuper using the existing 'extends' keyword like this:

{
"type" : "object",
"extends" : {
"type" : "object",
"javaType" : "model.AbstractModel"
}
}

Thank you for a quick response. Yes, it works by means of 'extends' feature.

It would be helpful to support generation serialVersionUID for Serializable classes also.

And may be the flag 'force' that forces generator overwrite existing classes also be helpful.

Changing the scope of this based on the fact that super type can already be accommodated via the 'extends' schema keyword.

Fixed for 0.3.7. There is now a new extension property "javaInterfaces" that takes an array of strings, where each string is the fully qualified name of a Java interface. The generated type will implement those interfaces.

Hi! Does this feature exist in the maven-plugin? I cannot seem to find it here.

EDIT: Sorry to bother. I found it here. I did not know that I would need to edit the schema because I was expecting it to be a configuration. I am not complaining was just looking in the wrong place I guess.
