Quartz 定时邮件发送多个备份文件

项目代码

pom.xml 文件
Quartz 的包是整个项目不可缺少的

MyJob.java 继承 QuartzJobBean 然后 Override
有钻研精神的可以一点一点扒代码看 QuartzJobBean 。

  1 import org.quartz.JobExecutionContext;
  2 import org.quartz.JobExecutionException;
  3 import org.slf4j.Logger;
  4 import org.slf4j.LoggerFactory;
  5 import org.springframework.scheduling.quartz.QuartzJobBean;
  6
  7 import java.util.Date;

  9 /**
 10  * kzyuan Job 参考
 11  * @description black husk
 12  * @description http://www.bhusk.com
 13  */
 14 public class MyJob extends QuartzJobBean {
 15
 16     private static Logger logger = LoggerFactory.getLogger(DatabaseBackupJob.class);
 17
 18     @Override
 19     protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
 20
 21         System.out.println("执行时间:"+new Date());
 22     }
 23 }

application.xml 可以理解为 quartz 配置文件 注释很齐全

JavaMail 发送邮件工具类
java 实现邮件的发送， 抄送及多附件
这个工具类来源网络，具体精准位置也不清楚了

  1         // 设置发件人
  2 //          mimeMsg.setFrom(new InternetAddress(from));
  3             mimeMsg.setFrom(new InternetAddress(from, nick));
