导出可运行文件

生成下面这样的文件

下面就开始 jar 转 exe

打开 exe4j
我 win10 jdk8 忽略没问题，不用管

首页

下一步

选 jar in exe mode,下一步

写好名字，选好输出目录，下一步

勾选单应用，下一步

上面 gif 很清楚，加入 jar 和外面引用的库类 jar,指定 main 方法，下一步

选好 jdk 版本，进入 search sequence

删除之前原有的设置，只设置一个 .\jre,下一步

下一步，下一步，最后

1.8 的 32 位 jre 放进去

==========================end==========================

只是做了表格处理，只是一个 demo，有问题可以留言
