How to scan classes for specific annotations and collect its values

Here the solution:

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import org.burningwave.core.assembler.ComponentContainer;
import org.burningwave.core.classes.hunter.ClassHunter;
import org.burningwave.core.classes.hunter.SearchCriteria;
import org.burningwave.core.classes.hunter.SearchForPathCriteria;
import org.burningwave.core.io.PathHelper;


public class Finder {

    public List<String> find() {
        ComponentContainer componentConatiner = ComponentContainer.getInstance();
        PathHelper pathHelper = componentConatiner.getPathHelper();
        ClassHunter classHunter = componentConatiner.getClassHunter();

        SearchForPathCriteria criteria = SearchCriteria.forPaths(
            //Here you can add all absolute path you want:
            //both folders, zip and jar will be recursively scanned.
            //For example you can add: "C:\\Users\\.m2"
            //With the row below the search will be executed on runtime Classpaths
            pathHelper.getMainClassPaths()
        ).allThat((cls) -> {
            return
                //Unconment one of this if you need to filter for package name
                //cls.getPackage().getName().matches("regular expression") &&
                //cls.getPackage().getName().startsWith("com") &&
                //cls.getPackage().getName().equals("com.something") &&
                cls.getAnnotation(Controller.class) != null &&
                cls.getAnnotation(RequestMapping.class) != null;
        });

        List<String> pathsList = classHunter.findBy(criteria).getItemsFound().stream().map(
            cls -> Arrays.asList(cls.getAnnotation(RequestMapping.class).value())
        ).flatMap(List::stream).distinct().collect(Collectors.toList());

        return pathsList;
    }

}
