如何从Hibernate元数据中获取特定类/实体的所有子类的列表？

SessionFactory sessionFactory = ...; // 获取SessionFactory对象
Configuration configuration = sessionFactory.getConfiguration();

Map<String, ClassMetadata> classMetadataMap = configuration.getClassMappings();
List<Class<?>> subclasses = new ArrayList<>();

for (ClassMetadata classMetadata : classMetadataMap.values()) {
    Class<?> mappedClass = classMetadata.getMappedClass();
    Class<?>[] mappedSubclasses = mappedClass.getSubclasses();

    subclasses.addAll(Arrays.asList(mappedSubclasses));
}

// subclasses 列表中包含了特定类/实体的所有子类
