1 背景概述 相信很多了解数通畅联软件的人对AEAI DP应用开发平台并不陌生,笔者在入职第一天就开始接触AEAI DP,使用AEAI DP开发过AEAI WM.AEAI CRM以及中国XXXX管理系统项目,在此过程中对AEAI DP有了较为深入了解,工作之余尝试对AEAI DP的工作原理.实际开发工作涉及的技术点进行梳理,希望能够对其他AEAI DP初学者和使用人员有所帮助. 本文相关说明涵盖AEAI DP的远程热部署新特性,AEAI DP V3.5以后版本支持按工程.模块.资源不同粒度实现代

Assert(断言)的初步理解构思 Web 应用在接受表单提交的数据后都需要对其进行合法性检查,如果表单数据不合法,请求将被驳回.类似的,当我们在编写类的方法时,也常常需要对方法入参进行合 法性检查,如果入参不符合要求,方法将通过抛出异常的方式拒绝后续处理.举一个例子:有一个根据文件名获取输入流的方法:InputStream getData(String file),为了使方法能够成功执行,必须保证 file 入参不能为 null 或空白字符,否则根本无须进行后继的处理.这时方法的编写者通常会在
