# Apache Commons Email组件介绍使用 #

## 介绍 ##

发送邮件功能这几乎是很多应用程序都会使用到的，所以Apache Commons提供了Email组件便捷的发送邮件方式。
    只需要简单的几个步骤就能够达到发送邮件的功能。

--------------------

## 几种常见的发送邮件格式 ##

### SimpleEmail(普通文本) ###

// 定义发送简单邮件对象
        SimpleEmail simpleEmail = new SimpleEmail();
    
        // 设置SMTP服务器,比如:smtp.163.com
        // Set the hostname of the outgoing mail server.
        simpleEmail.setHostName("smtp.163.com");
        // 设置登入认证服务器的用户名和密码
        // Sets the userName and password if authentication is needed. If this
        // method is not used, no authentication will be performed.
        simpleEmail.setAuthentication("username", "password");
    
        // 默认是25端口
        simpleEmail.setSmtpPort(25);
        // SSL enabled SMTP server,即如果是支持SSL服务器的端口是465
        // simpleEmail.setSmtpPort(465);//gmail邮箱服务器就是支持SSL的。
    
        // 设置发送人邮箱和名字
        simpleEmail.setFrom("xxx@163.com", "xuyi", "utf-8");
    
        // 设置收件人可以是多个
        simpleEmail.addTo("xxx@qq.com", "sky-xuyi");
        // simpleEmail.addTo(String ...emails);
    
        // 设置发送主题
        simpleEmail.setSubject("use apache email send mial");
    
        // 设置发送主体内容
        simpleEmail.setMsg("apache commons emial is a very good commonent for send email");
    
        // 确定发送邮件动作
        simpleEmail.send();
        System.out.println("send mail success");
