AutoEmail

AutoEmail - 写了个监听文件修改，自动发送修改文件提示邮件的程序

由于时间比较赶，现学一下午写的，很多细节没有考虑清楚，总体来说程序的鲁棒性并不算强。

内含Java环境，没装Java环境需要先装好。（实在没弄明白Exe4j和inno怎么用，做出来的setup还是不能在无jre机器上跑）

1 配置发件人邮箱

发送邮件首先需要有一个邮箱账号和密码，本文以QQ邮箱为例，邮箱账号必须要开启SMTP 服务，操作步骤如下：

• 首先登录网页版QQ邮箱（https://mail.qq.com）

• 点击“设置”

  

• 点击“账户”

  

• 向下滑动，找到“POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务”

  

  开启POP3/SMTP服务（示例图中已经开启）

• 点击“生成授权码”，按照提示完成操作

  

  请记录这一步的授权码，方便后面使用。

2 监听文件

在进行这一步操作前，请确保你已经按照要求完成了步骤1。

• 填写发件人

  发件人即你用来发送邮件的邮箱地址，本程序仅支持QQ/163/126邮箱。

• 填写密码

  这个密码并非qq邮箱的登录密码，而是第一步中的授权码。

• 填写收件人

  收件人即用来接收邮件的邮箱地址，这个地址可以是任何邮箱。

• 填写监听文件路径

  为了防止用户手动输入错误，此路径不能通过直接编辑更改。请点击“选择文件”按钮来选择你想要监听的文件。

• 设置监听间隔（秒）

  监听间隔表示程序每隔多少秒监测一次目标文件是否被修改。在程序启动时，这个监听间隔被默认设置为60秒，你也可以手动输入一个(geqslant 1)的整数来改变它。

最后，点击“开始/结束监测”，即可开始监听（再次按下本按钮可以停止监测）。

3 【推荐】导入已有的配置

为了避免每次运行本程序时，都需要重复填写一边收件人等基本信息，你可以将这些信息预先写入一个.txt文本文件中。

这个.txt文本文件记录着发件人、密码、收件人、监听文件、监听间隔。你应该仿照图例来编写此文件。

然后将该文件存储到一个位置（本例中，我们将其命名为'conf.txt'，你也可以更改为其他的名称）。然后，我们只需要点击导入已有配置按钮，选择刚刚存储的这个conf.txt，配置的信息就会被自动填充到程序中，最后点击开始/结束监测按钮即可。
