Spring获取某个包下带有特定注解的所有类的集合

 public Set<Class<?>> scanClassesWithAnnotation(String basePackage, Class<? extends Annotation> annotation) { 
        ClassPathScanningCandidateComponentProvider provider = new ClassPathScanningCandidateComponentProvider(false);
        provider.addIncludeFilter(new AnnotationTypeFilter(annotation));
        Set<BeanDefinition> candidates = provider.findCandidateComponents(basePackage);

        Set<Class<?>> classes = new HashSet<>();
        for (BeanDefinition candidate : candidates) {
            try {
                Class<?> clazz = Class.forName(candidate.getBeanClassName());
                classes.add(clazz);
            } catch (ClassNotFoundException e) {
                // Ignore exception
            }
        }
        return classes;
    }
