JavaMail发送邮件个人学习总结

1、Demo1发送文本内容邮件源码：package com.peng.sun;import java.util.Properties;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;public class Lession1 { String host = ""; String user = ""; String password = ""; public void setHost(String host) { this.host = host; } public void setAccount(String user, String password) { this.user = user; this.password = password; } public void send(String from, String to, String subject, String content) { Properties props = new Properties(); props.put("mail.smtp.host", host); // 指定SMTP服务器 props.put("mail.smtp.auth", "true"); // 指定是否需要SMTP验证 try { Session mailSession = Session.getDefaultInstance(props); Message message = new MimeMessage(mailSession); message.setFrom(new InternetAddress(from)); // 发件人 message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // 收件人 message.setSubject(subject); // 邮件主题 message.setText(content); // 邮件内容 message.saveChanges(); Transport transport = mailSession.getTransport("smtp"); transport.connect(host, user, password); transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch(Exception e) { System.out.println(e); } } public static void main(String[] args) { Lession1 sm = new Lession1(); sm.setHost("smtp.qiye.163.com"); // 指定要使用的邮件服务器 sm.setAccount("sunpeng@cfc-si.com", "*********"); // 指定帐号和密码 /* * @param String 发件人的地址 * * @param String 收件人地址 * * @param String 邮件标题 * * @param String 邮件正文 */ sm.send("sunpeng@cfc-si.com", "sunpeng2@cfc-si.com", "标题", "HelloWold!"); }}

2、Demo2发送HTML内容邮件//主要利用message.setContent(content, "text/ht罪焐芡拂ml;charset=utf-8");来实现发送html内容的邮件源码如下：package com.peng.sun;import java.util.Date;import java.util.Properties;import javax.mail.Message;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;public class Lession1 { String host = ""; String user = ""; String password = ""; public void setHost(String host) { this.host = host; } public void setAccount(String user, String password) { this.user = user; this.password = password; } public void send(String from, String to, String subject, String content) { Properties props = new Properties(); props.put("mail.smtp.host", host); // 指定SMTP服务器 props.put("mail.smtp.auth", "true"); // 指定是否需要SMTP验证 try { Session mailSession = Session.getDefaultInstance(props); Message message = new MimeMessage(mailSession); message.setFrom(new InternetAddress(from)); // 发件人 message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // 收件人 message.setSubject(subject); // 邮件主题 //指定邮箱内容及ContentType和编码方式 message.setContent(content, "text/html;charset=utf-8"); //指定邮件发送日期 message.setSentDate(new Date()); message.saveChanges(); Transport transport = mailSession.getTransport("smtp"); transport.connect(host, user, password); transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch(Exception e) { System.out.println(e); } } public static void main(String[] args) { Lession1 sm = new Lession1(); sm.setHost("smtp.qiye.163.com"); // 指定要使用的邮件服务器 sm.setAccount("sunpeng@cfc-si.com", "**********"); // 指定帐号和密码 /* * @param String 发件人的地址 * * @param String 收件人地址 * * @param String 邮件标题 * * @param String 邮件正文 */ sm.send("sunpeng@cfc-si.com", "sunpeng2@cfc-si.com", "标题", "<br>Hellor,World!<hr>"); }}

3、Demo3发送带附件的邮件有空接着写，谢谢关注！
