We are using hessian for java client server remoting. Now we need to change a interface to add a new field.
Is there any other way except to add a new interface.
the interface looks like
public void process(fieldA, fieldB)
we want to just to change the interface for adding a new field and add some logic to handle for backward compatibility like
public void process(fieldA, fieldB, fieldC){
if (StringUtils.isBlank(fieldC)){
old logic
} else{
new logic
}
Why can't you just add another method?
@Deprecated
public void process(fieldA, fieldB);
public void process(fieldA, fieldB, fieldC);
This should preserve backward compatibility.
