模型验证小型框架，用于检查模型是否正确验证。
对于模型开发的TDD（测试驱动开发）方法，我也很有用。
它几乎可以与任何测试框架一起使用！从NuGet安装它：:主要特点检查模型验证明际上是否因错误的值而失败。
检查是否已测试所有属性。
检查是否已测试所有类级别的验证属性。
检查是否已测试所有属性级别验证属性。
检查错误消息实际上是否正确。

poi解析excel功能参数说明此项目是基于springMVC实现的，基本流程为从前台jsp页面使用Ajax文件上传导入excel文件（.xls(97-03)/.xlsx(07以后)）,传到后台controller调用相应工具类解析后前往指定参数做后续处理.1.POIUtil.java工具类解析通过MutilpartFile导入的Excel并解析里面数据，先判断文件的类型(excel处理有两种此处为两种通用)是.xls/.xlsx，通过workbook.getNumberOfSheets()获取工作簿数量，遍历工作簿，sheet.getLastRowNum()获取最大行数，将每行数据放入Listlist=newArrayList()，并根据excel数据类型将器转换为字符串、数字、Boolean、公式、空值类型防止出现错误，最后前往一个list.2.ExcelUtil.java工具类解析通过MutilpartFile导入的Excel并解析里面数据，先判断文件的类型(excel处理有两种此处为两种通用)是.xls/.xlsx，采用Apache的POI的API来操作Excel，读取内容后保存到List中，再将List转Json（使用Linked，增删快，与Excel表顺序保持一致），Sheet表1————＞List1步骤1：根据Excel版本类型创建对于的Workbook以及CellSytle步骤2：遍历每一个表中的每一行的每一列，这里做了些小改动，因为后续可能解析过后可能会保存入数据库，这里为第一行数据添加一个自定义表头String[]p=newString[]{"name","age","sex","tel","address","e-mail","phone"};遍历的列数量以p的length为准步骤3：一个sheet表就是一个Json，多表就多Json，对应一个List一个sheet表的一行数据就是一个Map一行中的一列，就把当前列头为key，列值为value存到该列的Map中Map一个线性HashMap，以Excel的sheet表顺序，并以sheet表明作为key，sheet表转换Json后的字符串作为value最后前往一个LinkedHashMap3.ExcelToJsonPoi.java工具类这个与上面工具类类似，不过这个是解析本地excel文件不是使用的流，使用迭代遍历sheet工作簿与每行每列的值，将所有类型作为String类型处理前往一个json对象输出至控制台

场景假如有两个域名不同的服务器，a.com和b.com,在b.com/b_return_js.php这个接口里，可以获取一些数据。
当然，假如是b.com的页面里，可以运用ajax,直接请求这个接口，但如果在a.com的页面里如果请求呢。
b_return_js.php的接口代码：代码如下:$a=array(???array(‘username’=＞’tony’,‘age’=＞25),???array(‘username’=＞’yimeng’,‘age’=＞23),???array(‘username’=＞’ermeng’,‘age’=＞22),??

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
