lombok - Spring: Properly use of lombock Builder

Question

I faced with problem while using of lombock @Builder.

In SpringBoot application I create the following component:

@Getter
@Builder
@Component
@AllArgsConstructor
public class ContentDTO {
    private UUID uuid;
    private ContentAction contentAction;
    private String payload;
}

But when I run the application< I receive:

 Error creating bean with name 'contentDTO': Unsatisfied dependency expressed through constructor parameter 0

Caused by:

 No qualifying bean of type 'java.util.UUID' available: expected at least 1 bean which qualifies as autowire candidate

"Finger to the sky", I changed lombock-builder to custom builder, like this:

 @Getter
 @Component
public class ContentDTO {

  private ContentDTO() {       
  }

 // fields

  public static Builder newBuilder() {
       return new ContentDTO().new Builder();
  }

 public class Builder{
    private Builder() {
        private constructor
    }


  public ContentDTO build() {
       return ContentDTO.this;
      }     
   }
}

And problem is gone.

Its nice, but I clearly dont understand, what was problem!

Why in this case lombock-builder prevented the autowiring of beans?

And how to use lombock-builder properly in Spring ApplicationContext?

Answer 1

the use of the builder requires a default constructor. When you added the @AllArgsConstructor annotation the problem appears. therefore, you must also add the @NoArgsConstructor annotation. That should be the solution for your code.
