java 微信定时发消息给好友
作者：互联网
起因 ：加入一个新的公司 每周都要发感悟，这种死板重复的工作，作为一个程序员怎么能忍呀！ 肯定程序定时发呀 ！
准备工作 ： 微信pc版, 2 开发环境（jdk ,eclipse/intelliJ IDEA 等）
直接上程序

3 用IntelliJ IDEA 或者 Eclipse 打包可运行的jar
4配置执行参数 config.properties
a=a recipient=前数据处理开发群 sendTime=09:35:20 weixinPath=D:/Program Files (x86)/Tencent/WeChat/WeChat.exe contentPath=C:/Users/Administrator/Desktop/感悟.txtView Code
5配置bat文件 wxAuto.bat
@echo off
if "%1" == "h" goto head
mshta vbscript:createobject("wscript.shell").run("%~nx0 h",0)(window.close)&&exit
:head
cd C:\software\autoWX
java -jar wxAuto.jar
6配置windows 定时器
win+r 调出命令框 输入 compmgmt.msc
然后 配置定时器
