第二步：编写java提交post

} }第三步：部署到服务器上定时运行
①确认Linux环境。
确保系统时间为北京时间。
确保java环境配置完毕。
确保xshell连接正常。
②上传所需jar和写好的Java文件到Linux
用到的jar包有
activation-1.1.jar， fastjson-1.2.74.jar， javax.mail-1.6.0.jar，以及写好的程序daka.java
在xshell连接下用rz命令上传到目录
/root/mylearn/webapp/daka③操作权限解决：
修改使用文件夹的操作权限
sudo chmod -R 777 /root/mylearn/webapp/daka④Linux下带jar包编译与运行Java程序
jar包之间用:隔开，最后也要加。
javac -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: /root/mylearn/webapp/daka/daka.java得到class文件后，运行如下。
java -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: daka⑤写sh脚本并且配置定时运行
写sh脚本
vi daka.sh按i进入编辑，粘贴如下，：x保存退出。
#!/bin/bash cd /root/mylearn/webapp/daka java -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: daka配置定时
vi /etc/crontab #改类似定时，这里设置00：10分打卡 10 00 * * * root /root/mylearn/webapp/daka/daka.sh装载
crontab /etc/crontab重启定时服务
systemctl enable crond.service #开启启动 systemctl restart crond.service #重启服务结语
前几个月暑假无聊用python+appuim弄过一个自己打卡的脚本，就是滚屏幕模拟点击的那种。想把它部署到服务器，发现不现实，后来想到他打卡不就是个提交表单嘛，不就是个post嘛。所以搞了个这个，以后不用自己打卡了嘿嘿嘿！
