Java 发送邮件

使用Apache的Commons-email.jar 包进行邮件发送/接受的小测试。主要要注意以下几点：

1. 包要齐全，一共有四个包，他们分别为：javamail.jar, mail.jar, commons-email.jar, activation.jar

2. 在添加附件的时候，要将资源文件添加到Project中来

3. 如果要让附件显示您想要的格式，在别名中要写上后缀，如"逐梦令.mp3"

			attachment.setPath("./source/4 in love - 命中注定.mp3");
//			attachment.setName("destiny.mp3"); // if the suffix is added, then it can be displayed on what you want to see.
			attachment.setName("destiny.rmvb"); // if the suffix is added, then it can be displayed on what you want to see.
			attachment.setDescription(EmailAttachment.ATTACHMENT);
			email.attach(attachment);

File file = new File("./source/000.jpg");
			StringBuffer emailContent = new StringBuffer();
			emailContent.append("<html><body>");
			emailContent.append("<img src=cid:").append(email.embed(file,"阿兰")).append("/>");
			emailContent.append("<font color=\"red\">你好啊</font>");
			emailContent.append("</body></html>");
			
			email.setHtmlMsg(emailContent.toString());
			email.setTextMsg("测试");
			email.send();
