我们在开发业务系统时，少不的就是系统与系统间的交互, 一般是一个系统提供接口供另一个系统进行调用, 如A系统调用B系统的接口, A系统将接口需要的数据传入B, B根据相应的数据进行对应业务的处理, 但为了业务能够正常的运行, B系统会对A传入的数据进行校验, 为了使校验能够模块和标准化, B系统可以提供统一的配置和标准进行校验, 今天我们就实现一种方法， A传入数据后, B获取数据， 然后根据数据中的码值来调用xml配置进行标准化校验，校验成功后再执行相应的业务, 如果不成功，则回传错误信息

开发工具: Eclipse Mars, JDK1.7, Tomcat7
【项目包含内容】(见下图):
【DataValid】 源码
【接口文档.xlsx】 接口文档
【项目配置】
1. 将DataValid导入到Eclipse Mars中，JDK配置为JDK1.7, tomcat选择tomcat7
2. 接口文档.xlsx 中有相应数据标准格式, 代码是对数据格式的实现
【代码流程讲解】
1. A系统将数据按照上图的标准组装成json格式传给B系统
2. B系统获取json数据, 提取数据中的 transCode
3. B系统根据transCode组装校验数据的xml名称, transCode与xml校验文件是一一对应的
校验的xml内容如下: 判断内容是否为空; 校验长度; 校验时间格式等等
