    }

    代码先进行打包,Maven ——> clean ——> install

    代码运行测试

    选择jar文件,保存路径,点击生成即可。

    下载exe生成器

    1.

    exe4j : https://www.apponic.com/phome/download/95409-2-1593674778-a86aa6a3165855674c85c5a9dc7c8dbb/

    下载安装完成后,界面如图,
    第一步完成注册,Name,Company随便填就是了,注册码:A-XVK258563F-1p4lv7mg7sav (网上很多啊,随便搜一个就行)

     

    2.

    点击 next ,勾选JAR in EXE

    3.

    点击 next ,填写打包后的 exe程序名称和保存路径

    4.

    点击 next ,设置程序方式,兼容系统64位

    5.

    点击 next ,添加jar包,选择运行的主类的main方法

     

     

    6.

    点击 next ,设置JDK运行版本

    7.

    复制jre,放到jre的空文件夹下:D:/jre/jre

     

    8.

    加载jre环境

     

     

    9.

    一直点 next ,等待安装完成。

     10.

    尝试运行exe文件

      成功!!
