如何在类路径中找到具有特定方法注释的所有类？

import java.lang.annotation.Annotation;
import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;

public class ClassFinder {
    public static void main(String[] args) {
        List<Class<?>> classes = findClassesWithMethodAnnotation(MyAnnotation.class);
        for (Class<?> clazz : classes) {
            System.out.println("Found class: " + clazz.getName());
        }
    }

    public static List<Class<?>> findClassesWithMethodAnnotation(Class<? extends Annotation> annotationClass) {
        List<Class<?>> classes = new ArrayList<>();
        // 获取类加载器
        ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
        try {
            // 获取所有类路径下的类
            Enumeration<URL> urls = classLoader.getResources("");
            while (urls.hasMoreElements()) {
                URL url = urls.nextElement();
                // 获取类路径下的所有类文件
                File directory = new File(url.getFile());
                if (directory.isDirectory()) {
                    for (File file : directory.listFiles()) {
                        if (file.getName().endsWith(".class")) {
                            String className = file.getName().replace(".class", "").replace("/", ".");
                            Class<?> clazz = classLoader.loadClass(className);
                            // 检查类中是否存在具有特定注释的方法
                            for (Method method : clazz.getDeclaredMethods()) {
                                if (method.isAnnotationPresent(annotationClass)) {
                                    classes.add(clazz);
                                    break;
                                }
                            }
                        }
                    }
                }
            }
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }
        return classes;
    }
}
