How to run code after constructor in a Lombok builder

Question

I have a class that I want to use Lombok.Builder and I need pre-process of some parameters. Something like this:

@Builder
public class Foo {
   public String val         


        

Answer 1

This works for me, not a complete solution, but quick and easy.

@Builder
@AllArgsConstructor
public class Foo {
   @Builder.Default
   int bar = 42;
   Foo init() {
      // perform values initialisation
     bar = 451;   // replaces 314
     return foo;
   }
   static Foo test() {
       return new FooBuilder()  // defaults to 42
           .bar(314)  // replaces 42 with 314
           .build()
           .init();   // replaces 314 with 451
   }
}
