需求：只发送文本邮件（带图片和附件的未测试）

库版本：javamail-1.4.7

导入Java工程中jar包：mailapi.jar + smtp.jar

代码如下：

package com.buyu.mail;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;public class Mail {/** * 发送邮件 */public static boolean send(String smtp, String from, String to, String subject, String content, String username,String password) {try {// 1.设置SMTP主机Properties props = System.getProperties();props.put("mail.smtp.host", smtp);props.put("mail.smtp.auth", "true");// 2.创建MIME邮件对象Session session = Session.getDefaultInstance(props, null); // 获得邮件会话对象MimeMessage mimeMsg = new MimeMessage(session); // 创建MIME邮件对象Multipart mp = new MimeMultipart(); // Multipart对象,邮件内容,标题,附件等内容均添加到其中后再生成MimeMessage对象// 5.设置邮件主题mimeMsg.setSubject(subject);// 6.设置邮件正文BodyPart bp = new MimeBodyPart();bp.setContent("" + content, "text/html;charset=GBK");mp.addBodyPart(bp);// 7.设置发件人和收件人mimeMsg.setFrom(new InternetAddress(from));mimeMsg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));// 8.开始发送邮件mimeMsg.setContent(mp);Transport transport = session.getTransport("smtp");transport.connect((String) props.get("mail.smtp.host"), username, password);transport.sendMessage(mimeMsg, mimeMsg.getRecipients(Message.RecipientType.TO));transport.close();System.out.println("发送邮件成功！");} catch (Exception e) {System.err.println("邮件发送失败！");return false;}return true;}}

调用实例：

String smtp = "smtp.163.com";String from = "xxx@163.com";String to = "xxx@qq.com";String subject = "主题xxx";String content = "内容xxx";String username = "xxx@163.com";String password = "密码xxx";Mail.send(smtp, from, to, subject, content, username, password);
