package com.spring.until; import java.security.GeneralSecurityException; import java.util.Properties; import javax.mail.Authenticator; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import com.sun.mail.util.MailSSLSocketFactory; public class SendEmail { public static boolean send(String email,String title,String body) throws GeneralSecurityException { // 收件人电子邮箱 String to = email; // 发件人电子邮箱 String from = PropertiesUntil.Properties("account"); // 指定发送邮件的主机为 smtp.qq.com String host = "smtp.qq.com"; //QQ 邮件服务器 // 获取系统属性 Properties properties = System.getProperties(); // 设置邮件服务器 properties.setProperty("mail.smtp.host", host); properties.put("mail.smtp.auth", "true"); MailSSLSocketFactory sf = new MailSSLSocketFactory(); sf.setTrustAllHosts(true); properties.put("mail.smtp.ssl.enable", "true"); properties.put("mail.smtp.ssl.socketFactory", sf); // 获取默认session对象 Session session = Session.getDefaultInstance(properties,new Authenticator(){ public PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication( PropertiesUntil.Properties("account"), PropertiesUntil.Properties("password")); //发件人邮件用户名、密码 } }); try{ // 创建默认的 MimeMessage 对象 MimeMessage message = new MimeMessage(session); // Set From: 头部头字段 message.setFrom(new InternetAddress(from)); // Set To: 头部头字段 message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); // Set Subject: 头部头字段 message.setSubject(title); // 设置消息体 message.setText(body); // 发送消息 Transport.send(message); return true; }catch (MessagingException mex) { return false; } } }

PropertiesUntil.Properties(“account”) 发送人邮箱账号
PropertiesUntil.Properties(“password”) 发送人邮件密码，注意是刚刚生成的
