写在前面的话
网上很多文章都是针对配置文件来说的,本文是对<spring各种邮件发送>这篇文章作了封装,使用spring发送Email更加方便
网易和其它很多公司现在都没有对外开放POP3/SMTP服务,可能你会碰到这样的错误:
org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is javax.mail.AuthenticationFailedException
我测试时是用的是：新浪的邮箱:smtp.sina.com也是可以的
如下设置:

Exception: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection
参考文章:http://zhidao.baidu.com/question/227409027.html
解答: 配置JavaMail的Properties时，不要指定mail.smtp.socketFactory.class,因为TLS使用的是普通的Socket。然后指定属性mail.smtp.starttls.enable为true.

介绍
Spring邮件抽象层的主要包为org.springframework.mail。它包括了发送电子邮件的主要接口MailSender，和值对象SimpleMailMessage，
它封装了简单邮件的属性如from, to,cc, subject,text。包里还包含一棵以MailException为根的checked Exception继承树，
它们提供了对底层邮件系统异常的高级别抽象.为了使用JavaMail中的一些特色, 比如MIME类型的信件, Spring提供了MailSender的一个子接口,
即org.springframework.mail.javamail.JavaMailSender。Spring还提供了一个回调接口org.springframework.mail.javamail.MimeMessagePreparator,
用于准备JavaMail的MIME信件.

工程环境:XP+Myeclipse6.5+JDK1.6

一实现功能
1 封装了常用的四种发送Email的方法(文本,html,img,file),用户只要调用一个工厂类传递相应的邮件的属性如from, to,cc, subject,text,或者是消息对象
2 解决了发送邮件附件中的中文筹码问题,参见了<Spring Mail中文乱码问题>
3 支持链式风格
4 可以混合发送多种消息(text,html,img,file)

二工程图片

或者你也可以这样,使用打包好的jar:email.spring.util.jar

,见附件
三调用说明
1 发送文本消息

 //默认空构造为发送文本类型
//默认空构造为发送文本类型
		MailMessageFactory mms = new MailMessageFactory();
		mms.setSubject("使用spring email 测试发送文本消息")
		.setText("正文消息了。。。。")
		.send();

2 发送Html格式消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.HTML);
		mms.setSubject("使用spring email 测试发送Html中文邮件")
		.setText("<html><head><meta http-equiv='content-type' content='text/html; charset=GBK'>" +
				"</head><body><h1>这里是咫尺天涯发送的邮件</h1></body></html>").send();

3 发送含有图片的消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.HTML);				
		 String text = "<html><body>欢迎访问咫尺天涯博客<br>"
                + "<a href='http://liuzidong.iteye.com/' target='_blank'>"
                + "<img src='cid:belle'></a><br><img src='cid:belle2'></body></html>";  
		 //附件要嵌入到HTML中显示，则在IMG标签中用"cid:XXX"标记。               
		mms.setSubject("使用spring email 测试邮件中嵌套图片");	
		mms.setText(text);
		File file = new File("c:\\5.jpg");			
		mms.setImgFile("belle", file);		
		File file2 = new File("c:\\4.jpg");
		mms.setImgFile("belle2", file2);	
		mms.send();

4 发送含有附件的消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.HTML);
		mms.setSubject("使用spring email 测试发送附件");
		File file = new File("c:\\1.zip");
		mms.setAttachmentFile("jquery学习记录", file).send();

5 综合发送(文本,html,img,file)消息

MailMessageFactory mms = new MailMessageFactory(SendMailType.HTML);
		mms.setSubject("使用spring email 测试发送邮件<包含html,img,file>等格式");		
		mms.setText("这是我的文本格式");
		mms.setText("<html><head><h1>这里是咫尺天涯发送的邮件</h1></head><body>" +
				"<h1><a href='http://liuzidong.iteye.com/' target='_blank'></h1><br>" +
				"<img src='cid:belle'></a><br><img src='cid:belle2'>"+
				"</body></html>");
		 //附件要嵌入到HTML中显示，则在IMG标签中用"cid:XXX"标记。 
		File file = new File("c:\\5.jpg");
		mms.setImgFile("belle", file);		
		File file2 = new File("c:\\4.jpg");
		mms.setImgFile("belle2", file2);		
		File file3 = new File("c:\\1.zip");
		mms.setAttachmentFile("附件1", file3);		
		File file4 = new File("c:\\jquery学习记录.txt");
		mms.setAttachmentFile("jquery学习记录", file4);		
		mms.send();
