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; 8 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)); 4 // 设置收件人 5 if (to != null && to.length() > 0) { 6 mimeMsg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); 7 } 8 // 设置抄送人 9 if (cc != null && cc.length() > 0) { 10 mimeMsg.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc)); 11 } 12 // 设置主题 13 mimeMsg.setSubject(subject); 14 // 设置正文 15 BodyPart bp = new MimeBodyPart(); 16 bp.setContent(content, "text/html;charset=utf-8"); 17 mp.addBodyPart(bp); 18 // 设置附件 19 if (fileList != null && fileList.length > 0) { 20 for (int i = 0; i < fileList.length; i++) { 21 bp = new MimeBodyPart(); 22 FileDataSource fds = new FileDataSource(fileList[i]); 23 bp.setDataHandler(new DataHandler(fds)); 24 bp.setFileName(MimeUtility.encodeText(fds.getName(), "UTF-8", "B")); 25 mp.addBodyPart(bp); 26 } 27 } 28 mimeMsg.setContent(mp); 29 mimeMsg.saveChanges(); 30 // 发送邮件 31 if (props.get("mail.smtp.auth").equals("true")) { 32 Transport transport = session.getTransport("smtp"); 33 transport.connect((String) props.get("mail.smtp.host"), (String) props.get("username"), (String) props.get("password")); 34 transport.sendMessage(mimeMsg, mimeMsg.getAllRecipients()); 35 transport.close(); 36 } else { 37 Transport.send(mimeMsg); 38 } 39 System.out.println("邮件发送成功"); 40 } catch (MessagingException e) { 41 e.printStackTrace(); 42 success = false; 43 } catch (UnsupportedEncodingException e) { 44 e.printStackTrace(); 45 success = false; 46 } 47 return success; 48 } 49 50 public String getMailList(String[] mailArray) { 51 StringBuffer toList = new StringBuffer(); 52 int length = mailArray.length; 53 if (mailArray != null && length < 2) { 54 toList.append(mailArray[0]); 55 } else { 56 for (int i = 0; i < length; i++) { 57 toList.append(mailArray[i]); 58 if (i != (length - 1)) { 59 toList.append(","); 60 } 61 62 } 63 } 64 return toList.toString(); 65 } 66 67 public static void main(String[] args) { 68 String from = username; 69 String[] to = {"keshu@bhusk.com", "1520812121@qq.com"}; 70 String[] copyto = {"lu12121@qq.com"}; 71 String subject = "黑壳网数据库备份"; 72 String content = "没有数据就没有一切，数据库备份就是一种防范灾难于未然的强力手段，没有了数据，应用再花哨也是镜中花水中月。"; 73 String[] fileList = new String[2]; 74 fileList[0] = "~/solo_h2/db.mv.db"; 75 fileList[1] = "~/solo_h2/db.trace.db"; 76 77 EmailManager.getInstance().sendMail(from, to, copyto, subject, content, fileList); 78 } 79 }
