java学习-mail应用

Properties p=new Properties();
p.put("mail.transport.protocol", "smtp"); 
p.put("mail.smtp.auth", "true"); //密码验证
p.put("mail.smtp.host","localhost" ); //主机
p.put("mail.smtp.port", 25); //端口号
p.put("mail.debug", "true");//调试模式

简单的邮件
Session mailsession=Session.getDefaultInstance(p);  //获取邮件会话
MimeMessage message=new MimeMessage(mailsession);//邮件体对象
message.setFrom(new InternetAddress("[email protected]")); //发件人
message.setRecipient(RecipientType.TO, new InternetAddress("[email protected]")); //收件人
message.setSubject("正文");  //设置标题
message.setSentDate(new Date()); //设置日期
message.setText("你好，man;欢迎来到即刻 ");  //设置文本
message.setContent("<a href='www.baidu.com'>百度</a>","text/html;charset=utf-8");
message.saveChanges();  //保存邮件

创建一个多功能的邮件
MimeMultipart related=new MimeMultipart("related");
MimeBodyPart content=new MimeBodyPart();
MimeBodyPart resource=new MimeBodyPart();
String path=App_1SendMail.class.getResource("1.jpg").getPath();  //图片放于java文件下面，在包内
DataSource ds=new FileDataSource(new File(path));
DataHandler handler=new DataHandler(ds);
resource.setDataHandler(handler);
resource.setContentID("1.jpg");
content.setContent("<img src='cid:1.jpg'/>"," text/html;charset=utf-8");
related.addBodyPart(resource);
related.addBodyPart(content);
message.setContent(related);
message.saveChanges();   // 保存邮件(可选)

带图片和附近的邮件
MimeMultipart mut=new MimeMultipart("mixed");
MimeBodyPart left=new MimeBodyPart();
MimeBodyPart right=new MimeBodyPart();
MimeMultipart related=new MimeMultipart("related");
//左侧
MimeBodyPart content=new MimeBodyPart();  //文本
MimeBodyPart resource=new MimeBodyPart();  //资源
String path=this.getClass().getResource("1.jpg").getPath();
DataSource ds=new FileDataSource(new File(path));
DataHandler handler=new DataHandler(ds);
resource.setDataHandler(handler);
resource.setContentID("1.jpg");
content.setContent("<img src='cid:1.jpg'>","text/html;charset=utf-8");
related.addBodyPart(content);
related.addBodyPart(resource);
left.setContent(related);
//右侧
String attr_path = this.getClass().getResource("a.docx").getPath();
DataSource attr_ds = new FileDataSource(new File(attr_path));
DataHandler attr_handler = new DataHandler(attr_ds);
right.setDataHandler(attr_handler);
right.setFileName("a.docx");
// 设置到总邮件块
mut.addBodyPart(left);
mut.addBodyPart(right);
message.setContent(mut);




//发送
Transport tr=mailsession.getTransport();
tr.connect("zhangsan", "12345678"); //发件人的用户名和密码
tr.sendMessage(message, message.getAllRecipients());
tr.close();
