java 實現郵件推送

Java實現郵件推送功能

一、引入依賴

 <dependency>
 ? ? ? ? ? ?<groupId>org.apache.commons</groupId>
 ? ? ? ? ? ?<artifactId>commons-email</artifactId>
 ? ? ? ? ? ?<version>1.4</version>
 </dependency>

二、郵件來源用戶信息

private static Logger log = Log.getLogger();
private static ThreadPoolExecutor threadPool;
private static String emailServer;
private static String userName;
private static String password;
private static String emailEncoding;
private static String emailFrom;
private static String sysEmailFromName;
private static String encoding;
    
private static void initMail(Email mail) throws EmailException {
    mail.setHostName(emailServer);
    mail.setAuthentication(userName, password);
    mail.setCharset(emailEncoding);
    mail.setFrom(emailFrom, sysEmailFromName);
}

三、線程池異步

static {
    threadPool = new ThreadPoolExecutor(5, 10, 3L, TimeUnit.SECONDS, new ArrayBlockingQueue(50), new ThreadPoolExecutor.DiscardPolicy());
    //郵箱服務器地址
    emailServer = "smtp.163.com";
    //用戶名
    userName = "****";
    //用戶密碼
    password = "****";
    //編碼格式
    emailEncoding = "GBK";
    //郵件來源
    emailFrom = "*****.com.cn";
    //郵件來源用戶名稱
    sysEmailFromName = "****";
    //編碼格式
    encoding = "UTF-8";
}
?

四、異步發(fā)送

 private static void sendMail(Email mail) {
 ? ? ?  threadPool.execute(new Runnable() {
 ? ? ? ? ?  @Override
 ? ? ? ? ?  public void run() {
 ? ? ? ? ? ? ?  try {
 ? ? ? ? ? ? ? ? ?  mail.send();
 ? ? ? ? ? ? ?  } catch (EmailException var2) {
 ? ? ? ? ? ? ? ? ?  log.error("[郵件抄送失敗]-", var2);
 ? ? ? ? ? ? ?  }
 ? ? ? ? ?  }
 ? ? ?  });
 ?  }
