Apache Commons Email(必须的三个Jar activation.jar commons-email-1.1.jar mail.jar)
一 、Apache Commons Email简介
Apache Commons Email是Apache提供的一个用于发送email 的API。 Email组件是构建在Java Mail API基础之上，是对Java Mail的封装。

二 、Apache Commons Email功能
1 发送普通文本格式邮件
2 发送可添加附件的、普通文本格式邮件
3 发送可添加附件的、HTML格式邮件

三 、Apache Commons Email使用
环境配置：Email组件是构建在Java Mail API基础之上，是对Java Mail的封装。因此在使用时，除了需要将Apache Commons Email本身的jar包引入外， 还需将javamail.jar加到 class path中。

Apache Commons Email主要包括以下4个类：
1 SimpleEmail ? 发送简单的email，不能添加附件。
2 MultiPartEmail ? 文本邮件，可以添加多个附件。
3 HtmlEmail ? HTML格式邮件，同时具有MultiPartEmail类所有“功能”。
4 EmailAttchment ? 附件类，可以添加本地资源，也可以指定网络上资源，在发送时自动将网络上资源下载发送。

//发送普通文本格式email：
SimpleEmail email = new SimpleEmail();
// 设置邮件编码
email.setCharset("UTF-8");
// 设置邮件服务器
email.setHostName("smtp.sohu.com");
// 设置登录邮件服务器用户名和密码
email.setAuthentication("zhangsan@sohu.com", "123456");
// 添加收件人
email.addTo("lisi@qq.com", "lisi");
// 设置发件人
email.setFrom("zhangsan@sohu.com", "zhangsan");
// 设置邮件标题
email.setSubject("Happy New Year");
// 设置邮件正文内容
email.setMsg("Hi, i'm zhangsan. Happy new year to you !");
// 发送邮件
email.send();

//发送带附件的、普通格式邮件：


MultiPartEmail email = new MultiPartEmail();

// 设置邮件编码

email.setCharset(“UTF-8”);

// 设置邮件服务器

email.setHostName(“smtp.sohu.com”);

// 设置登录邮件服务器用户名和密码

email.setAuthentication(“zhangsan@sohu.com”, “123456”);

// 设置邮件正文内容

email.setMsg(“Hi, i’m zhangsan. Happy new year to you !”);

// 要发送的附件

EmailAttachment attachment = new EmailAttachment();

File file = new File(“D:\attachment.jar”);

attachment.setPath(file.getPath());

attachment.setName(file.getName());

// 设置附件描述

attachment.setDescription(“Attachment Description”);

// 设置附件类型

attachment.setDisposition(EmailAttachment.ATTACHMENT);

// 添加附件

email.attach(attachment);

// 发送邮件

email.send();


//发送带附件的、HTML格式邮件：


HtmlEmail email = new HtmlEmail();

// 设置邮件编码

email.setCharset(“UTF-8”);

// 设置邮件服务器

email.setHostName(“smtp.sohu.com”);

// 设置登录邮件服务器用户名和密码

email.setAuthentication(“zhangsan@sohu.com”, “123456”);

// 添加收件人

email.addTo(“lisi@qq.com”, “lisi”);

// 设置发件人

email.setFrom(“zhangsan@sohu.com”, “zhangsan”);

// 设置邮件标题

email.setSubject(“Happy New Year”);

// 设置邮件正文内容

email.setHtmlMsg(“Hi, i’m zhangsan.”);

EmailAttachment attachment = new EmailAttachment();

// 要发送的附件

File file = new File(“D:\attachment.jar”);

attachment.setPath(file.getPath());

attachment.setName(file.getName());

// 设置附件描述

attachment.setDescription(“Attachment Description”);

// 设置附件类型

attachment.setDisposition(EmailAttachment.ATTACHMENT);
