把java做成linux脚本（类似小工具）
java 最轻便的部署方式
D:\2020工作计划\2020-09-08\New Folder\checke-chai-data>
- 目录结构如下
- lib 是放编译好的class 文件的依赖
- readFile 不用关心
- .sh 是脚本文件
图一
HttpsPostRequestWithClientKey这个类必须放在根目录下（src 目录下， 放在默认包下）
图二
在工程目录下找到该java 文件的编译文件（.class文件）复制到图一目录
图三
HttpsPostRequestWithClientKey这个类所依赖的jar 包需要放在图1 的lib 目录下
这样其实就已经可以跑起来了， 如果在window 环境可以直接在图1目录栏输入cmd 进入命令窗口启动程序
进入
图四
score 是参数， 可选
java -cp “.:./lib/" HttpsPostRequestWithClientKey score（windows）
放入文件 .bat 文件中就可以双击运行
java -cp ".；./lib/” HttpsPostRequestWithClientKey score (linux)
放入.sh 就可以 ./ 运行了
