把list类型转为List<clazz> 类型，其中，值为null时转为空字符串
public static <T> List<T> listFomart(List list, Class<T> clazz) { List<T> result = new ArrayList<>(); list.forEach(item -> { result.add(JSON.parseObject(JSON.toJSONString(item, SerializerFeature.WriteNullStringAsEmpty), clazz, Feature.InitStringFieldAsEmpty)); }); return result; }
