本篇,我们尝试使用java开发一个图形化小工具(rsaTool)。
最终运行效果如下: 界面最上方有4个tab标签, 这4个标签页中分别实现了rsa加密、解密、签名、验签的功能。
下面我们来具体介绍下项目代码开发过程。
此项目使用的IDE是spring STS ,由于开发的是GUI程序,我们可以先安装一款可视化编辑器工具windowbuilder ,安装步骤如图:
在 help--》eclipse Marketplace --》search --》windowbuilder--》 安装 即可。
new一个java工程,起名为rsaTool。
java开发人员,无论开发什么都必须面向对象,对整个项目进行MVC划分。
img :图标资源
model: 模型层 ,java实体bean,业务bean等。
view :视图层,主要是JFrame 窗体等
由于RSA加解密需要依赖包 bcprov-jdk16-1.46.jar ,故需要在项目根目录中新建一个lib目录,将bcprov-jdk16-1.46.jar放入lib目录中并加入classpath 中。
ok,我们先来看看model 模型层 : 有两个工具类,一个业务类。
