java 微信定时发消息给好友

本文主要是介绍java 微信定时发消息给好友，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

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.txt

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
