在java里遍历包下的所有类

//遍历包下的所有类
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AssignableTypeFilter(GeneratedMessageV3.class));
Set<BeanDefinition> beanDefinitions = scanner.findCandidateComponents("proto");
for (BeanDefinition beanDefinition : beanDefinitions) {
    log.info(beanDefinition.getBeanClassName());
    try {
        list.add(Class.forName(beanDefinition.getBeanClassName()));
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
}

log.info("{}", list);
