玩转exchange(查找邮件,修改邮件,发送邮件)

背景:

每天早上需要发站会纪要,纪要内容为组员昨日的工作完成情况,工作完成情况需要从每个组员的exchange邮件中选择昨日发的日报邮件,提取信息,因组员很多,每天这种重复的复制粘贴操作很麻烦,就想到了用java写个程序来完成这个事。

概念:

exchage 与 outlook
Exchange是服务器端的软件,而Outlook是其客户端的软件。只是Outlook不仅仅可以作为Exchange的客户端,还可以接收其他支持Pop3等的邮件,当然,Exchange邮件接收方式也不仅仅局限于使用Outlook,你也可以使用Foxmail等其他软件,也可以通过Web方式使用OWA方式接收。(PS:在网上搜索API的时候千万不要搜outlook相关的api,因为是针对exchange服务端进行邮件的操作,而非outlook,虽然我们在客户端使用的outlook)

方法:

步骤:

  1. 连接exchange
  2. 查找自己邮件中的组员邮件,并保存
  3. 查找日报模板邮件,并在指定位置替换成组员邮件中的信息
  4. 发送邮件

代码:

  • domain
package outlook.meeting
 
class UserStandMeeting {
 
    static constraints = {
 
    }
 
    UserStandMeeting(List<String> yesterdayWork,List<String> todayWork,List<String> progress){
        this.yesterdayWork = yesterdayWork
        this.todayWork = todayWork
        this.progress = progress
    }
 
    //成员姓名
    String member
    //昨日工作列表
    List<String> yesterdayWork
    //今日工作列表
    List<String> todayWork
    //昨日工作进度
    List<String> progress
}
