JavaMail邮件发送-为你的邮件增加背景音乐和背景图片

先搞一个增加背景图片

 

首先要准备图片，这个图片可以是本地的也可以是远程的

如果你使用本地的，那么会有一些问题，稍后再说，大家也帮忙给看看问题

 

如果是使用了远程，那很简单，就是发送一个HTML格式的邮件而已：

package com.mail;
 import java.util.Date;
 import java.util.Properties;
 import javax.mail.BodyPart;
 import javax.mail.Message;
 import javax.mail.Multipart;
 import javax.mail.Session;
 import javax.mail.Transport;
 import javax.mail.internet.InternetAddress;
 import javax.mail.internet.MimeBodyPart;
 import javax.mail.internet.MimeMessage;
 import javax.mail.internet.MimeMultipart;
 import javax.mail.internet.MimeUtility;
 public class HtmlMail {
     public static void main(String[] args) throws Exception {
         Properties props = new Properties();
         props.put( "mail.smtp.host ", "smtp.163.com ");
         props.put("mail.smtp.auth", "true");
        Session session = Session.getInstance(props);
         Message message = new MimeMessage(session);
         InternetAddress from = new InternetAddress("[email protected]");
         from.setPersonal(MimeUtility.encodeText("风中落叶"));
        message.setFrom(from);
         InternetAddress to = new InternetAddress("[email protected]");
        message.setRecipient(Message.RecipientType.TO, to);
         message.setSubject(MimeUtility.encodeText("强哥邀请，谁敢不从！"));
         message.setSentDate(new Date());
         // 构建邮件内容对象
         Multipart mm = new MimeMultipart();
         // 构建一个消息内容块
         BodyPart mbpFile = new MimeBodyPart();
         mbpFile.setContent("" +
                 "强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！","text/html;charset=UTF-8");
        mm.addBodyPart(mbpFile);
        message.setContent(mm);
        message.saveChanges();
         Transport transport = session.getTransport("smtp");
         transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");
        transport.sendMessage(message, message.getAllRecipients());
        transport.close();
         System.out.println("发送完毕");
    }
}

package com.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
import javax.mail.internet.MimeUtility;
public class HtmlMail {
	public static void main(String[] args) throws Exception {
		Properties props = new Properties();
		props.put( "mail.smtp.host ", "smtp.163.com ");
		props.put("mail.smtp.auth", "true");
		Session session = Session.getInstance(props);
		Message message = new MimeMessage(session);		
		InternetAddress from = new InternetAddress("[email protected]");
		from.setPersonal(MimeUtility.encodeText("风中落叶"));
		message.setFrom(from);		
		InternetAddress to = new InternetAddress("[email protected]");
		message.setRecipient(Message.RecipientType.TO, to);		
		message.setSubject(MimeUtility.encodeText("强哥邀请，谁敢不从！"));
		message.setSentDate(new Date());		
		// 构建邮件内容对象
		Multipart mm = new MimeMultipart();
		// 构建一个消息内容块
		BodyPart mbpFile = new MimeBodyPart();
		mbpFile.setContent("" +
				"强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！","text/html;charset=UTF-8");
		mm.addBodyPart(mbpFile);
		message.setContent(mm);
		message.saveChanges();
		Transport transport = session.getTransport("smtp");
		transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");
		transport.sendMessage(message, message.getAllRecipients());
		transport.close();
		System.out.println("发送完毕");
	}
}

 

想想也是，你的图片肯定是要放到一个服务器的，不然每次发送一个大包给人家，谁不烦

 

当然我还是说一下怎么增加图片直接放到消息包内

先贴代码后解释：

     public static void main(String[] args) throws Exception {
         Properties props = new Properties();
         props.put( "mail.smtp.host ", "smtp.163.com ");
         props.put("mail.smtp.auth", "true");
        Session session = Session.getInstance(props);
         Message message = new MimeMessage(session);
         InternetAddress from = new InternetAddress("[email protected]");
         from.setPersonal(MimeUtility.encodeText("风中落叶"));
        message.setFrom(from);
         InternetAddress to = new InternetAddress("[email protected]");
        message.setRecipient(Message.RecipientType.TO, to);
         message.setSubject(MimeUtility.encodeText("强哥邀请，谁敢不从！"));
         message.setSentDate(new Date());
         // 我就当这是一个消息包，类型是混杂的
         MimeMultipart msgMultipart = new MimeMultipart("mixed");// 指定为混合关系
        message.setContent(msgMultipart);
         // 这是消息包里面的一个消息体块
         MimeBodyPart content = new MimeBodyPart();
        msgMultipart.addBodyPart(content);
         // 消息体块包含了一组有依赖关系的元素
         MimeMultipart bodyMultipart = new MimeMultipart("related"); // 依赖关系
        content.setContent(bodyMultipart);
         // 这两个依赖关系的元素是HTML文本内容和依赖的图片资源
         MimeBodyPart htmlPart = new MimeBodyPart();
         MimeBodyPart gifPart = new MimeBodyPart();
         // TODO 组装的顺序非常重要，一定要先组装文本域
        bodyMultipart.addBodyPart(htmlPart);
        bodyMultipart.addBodyPart(gifPart);
         DataSource gifds = new FileDataSource("D:\\123.jpg");
         DataHandler gifdh = new DataHandler(gifds);
        gifPart.setDataHandler(gifdh);
         gifPart.setHeader("Content-Location", "bg.jpg");
        htmlPart.setContent(
                         ""

                                 + "这是测试邮件，请勿回复" + "

",   

                        "text/html;charset=UTF-8");        

        message.setContent(msgMultipart);

        transport.sendMessage(message, message.getAllRecipients());   

        transport.close();   

        System.out.println("发送完毕");   

    }

这个有点麻烦

首先是有一个 复杂关系的 MimeMultipart ，然后在这个对象里面增加一个消息体，这个消息体包含了一个是 依赖关系的包 ，这个包内又包含了两个元素

因为涉及到附件，所以你运行时会很慢

 

但是有一个问题

如果你这样指定，那么邮箱会人为你发送了两个普通附件，一个是图片一个是HTML文件

然后邮箱不会显示图片，只是把图片做为了一个普通附件，但是你要是用 foxmail 看的话就会显示

如果你看源码，会发现其实 foxmail  是把普通附件下载下来，然后图片就是显示本地文件了，而邮箱不会

谁知道怎么解决说一声！

 

如果是增加背景音乐的话，那就把上面的代码改一下，然后你的邮件内容是这样的

// 邮件内容
 mbpFile.setContent(""
         + "强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！" +
                 "您听到背景音乐了么？"
         + "", "text/html;charset=UTF-8");

// 邮件内容
mbpFile.setContent(""
		+ "强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！
" +
				"您听到背景音乐了么？"
		+ "", "text/html;charset=UTF-8");

 

发送后你用foxmail  打开就可以听到音乐！
