将HashMap反序列化为POJO并将空字段设置为null？

public static <T> T deserializeHashMap(HashMap<String, Object> hashMap, Class<T> clazz) throws Exception {
    T pojo = clazz.newInstance();
    for (Map.Entry<String, Object> entry : hashMap.entrySet()) {
        String fieldName = entry.getKey();
        Object value = entry.getValue();
        Field field = clazz.getDeclaredField(fieldName);
        field.setAccessible(true);
        field.set(pojo, value);
    }
    return pojo;
}
