Spring Data optional parameter in query method

Question

I want to write some query methods in repository layer. This method must ignore null parameters. For example:

List findByBarAndGoo(Bar barParam,          


        

Answer 1

You could code this yourself in just a few lines:

List findByBarAndOptionalGoo(Bar bar, Goo goo) {
   return (goo == null) ? this.findByBar(bar) : this.findByBarAndGoo(bar, goo);
}

Otherwise, I don't know if Spring-Data supports this out of the box.
