MiniUi框架简单实例
来源：互联网 发布：网络教育有学籍吗 编辑：程序博客网 时间：2024/05/09 08:06
这篇博客是在实习期间在公司写的，公司让用miniui来作为软件开发的前端框架，在学习了一段时间后做一个总结，算是给自己实习的一份小礼物吧。
首先，先来看看效果图，虽然比不上工作经验丰富的同事，但也可借鉴一番！
我设计显示了三个界面，这是第一个界面，只是简单的数据的增删改查界面，是我用来做后面两个界面的练手界面。
这是第二个界面，用来进行新增信息的界面，新增的信息保存后会在第三个界面显示。
这是第三个界面，用来显示表格数据的，同时也可进行修改和删除操作！
上面三张图就是这次要做的内容，希望对miniui新手有帮助！
一：准备篇
1：安装JDK、安装MyEclipse、安装Sqlserver(公司用的数据库)、tomcat7.0。
以上这些都是基础的内容，这里就不赘述了，不知道的度娘吧！
2：建数据库+建表。建数据库就不说了，可自行建立和取名字，给出两张表的数据字典，可以根据数据字典来建表。
这是第一张表，表的名字可以用数据字典上的名字。
这是第二张表，名字也按照数据字典来命名。
3：测试数据。在测试数据库中数据是否可以被MyEclipse获取到时，先在建好的表中添加适量的数据，数据的添加注意字段的类型。
3.1：ＪＤＢＣ连接。写一个TestDB.java类,并写jdbc连接代码。
3.2：在MyEclipse中创建数据库对象并连接。
点击Finish后右键数据库-->Open就可打开你创建的数据库
二：界面篇
1：框架界面，outlookmenu.jsp
