Java – Lombok builder containing existing data value classes

One library provides classes, such as org springframework. security. oauth2. provider. client. Baseclient details, which I want to wrap as a Lombok (or similar) builder

At present, I have derived such a wrapper class:

public static final class BaseClientDetailsWrapper
    extends BaseClientDetails {
    @Builder
    private BaseClientDetailsWrapper(
        final String clientId,final List<String> resourceIds,final List<GrantedAuthority> suthorities,final List<String> scopes,final List<String> autoApproveScopes,final List<String> authorizedGrantTypes,final String clientSecret) {
        super();
        setClientId(clientId);
        setResourceIds(resourceIds);
        setAuthorities(authorities);
        setScope(scopes);
        setAuthorizedGrantTypes(authorizedGrantTypes);
        setAutoApproveScopes(autoApproveScopes);
        setClientSecret(clientSecret);
    }
}

Is there any way to get rid of the annoying setXXX (...) code?

Solution

Is there a constructor that better meets your needs? No, there's no way to ask Lombok to treat other features as builder templates that you don't control

As a side note, there is no need to subclass baseclientdetails You can put @ builder on any function, no matter which class it is in The following are fully acceptable:

@Builder(builderMethodName = "fullname")
private static String fullnameHelper(String forename,String middle,String surname) {
    Objects.requireNonNull(forename);
    Objects.requireNonNull(surname);
    return forename + " " + (middle == null ? "" : middle + " ") + surname;
}

The name of the method is not important at all If necessary, you can hide it privately in the utility class You can use it this way:

fullname().forename("Alan").surname("Turing").build());
fullname().forename("Donald").middle("E.").surname("Knuth").build());
