java 实现邮件推送

Java实现邮件推送功能

一、引入依赖

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

二、邮件来源用户信息

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、线程池异步

static {
    threadPool = new ThreadPoolExecutor(5, 10, 3L, TimeUnit.SECONDS, new ArrayBlockingQueue(50), new ThreadPoolExecutor.DiscardPolicy());
    //邮箱服务器地址
    emailServer = "smtp.163.com";
    //用户名
    userName = "****";
    //用户密码
    password = "****";
    //编码格式
    emailEncoding = "GBK";
    //邮件来源
    emailFrom = "*****.com.cn";
    //邮件来源用户名称
    sysEmailFromName = "****";
    //编码格式
    encoding = "UTF-8";
}

四、异步发送

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