Spring MVC Generics Object Binding/Type Conversion

I'm looking for a way to wrap my models or DTOs with a generic class to add a 'selected' Boolean property and be able to bind the object in my POST method controller.



Like this:



public class RowForm<T> implements Serializable 

private static final long serialVersionUID = 1L;
private T model;
private Boolean selected=false;

public RowForm()
super();


public RowForm(T model)
super();
this.model = model;


public T getModel()
return model;


public void setModel(T model)
this.model = model;


public Boolean getSelected()
return selected;


public void setSelected(Boolean selected)
this.selected = selected;





public class ProductsForm implements Serializable

private static final long serialVersionUID = 1L;
private RowForm<Product> row;

//...other stuff and getters/setters



and use it like this:



 @PostMapping ("/postProduct")
public String POSTproduct(Model model, @ModelAttribute ProductsForm pf)

....



But I'm stuck with the conversion...



When I call pf.getRow() it returns a plain Object, not a RowForm<Product>.



How can I implement a ConversionService/PropertyEditor to bind my posted data to my extended generic object?

          Why not use a abstract base class with the selected property, and extend it for your DTOs?
