ArchRule for methods which have at least one argument of a given type

[jbader-berner]

I looking for an ArchRule which reports all methods which have at least on String parameter

        ArchRule rule = methods()
                .that()
                .areDeclaredInClassesThat()
                .areAnnotatedWith(Controller.class)
                .and()
                .arePublic()
                .and()
                // todo: search for methods which hase a String parameter (include methods which hase more then only string)
                .haveRawParameterTypes(String.class)
                .should()
                .beAnnotatedWith(PreAuthorize.class);

this method includes only methods that

public void m1(String s)

but the rule should also cover methods

public void m1(String s1, String s2) or
public void m1(Model model, String s1)

Any ideas?

You can implement a custom predicate:

static imports

import static com.tngtech.archunit.base.DescribedPredicate.describe;
import static com.tngtech.archunit.lang.conditions.ArchPredicates.have;

    ArchRule rule = methods()
            .that().areDeclaredInClassesThat().areAnnotatedWith(Controller.class)
            .and().arePublic()
            .and(have(describe("at least one String parameter", method ->
                    method.getRawParameterTypes().stream().anyMatch(parameter -> parameter.isEquivalentTo(String.class))
            )))
            .should().beAnnotatedWith(PreAuthorize.class);
