java发送email文件
1. 加入jar包
<dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.5.0-b01</version> </dependency>
2.编码如下:
方式1:
import java.util.Date; import java.util.Properties; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class EmailTest { public static String myEmailAccount = "mabiao008@126.com"; // 发件人邮箱地址 public static String myEmailPassword = "XXXXXX"; // 发件人邮箱密码 public static String myEmailSMTPHost = "smtp.126.com"; public static String receiveMailAccount = "360227812@qq.com"; // 收件人邮箱地址 public static void main(String[] args) throws Exception { // 1. 创建参数配置, 用于连接邮件服务器的参数配置 Properties props = new Properties(); // 参数配置 props.setProperty("mail.transport.protocol", "smtp"); // 使用的协议(JavaMail规范要求) props.setProperty("mail.host", myEmailSMTPHost); // 发件人的邮箱的 SMTP 服务器地址 props.setProperty("mail.smtp.auth", "true"); // 2. 根据配置创建会话对象, 用于和邮件服务器交互 Session session = Session.getDefaultInstance(props); session.setDebug(true); // 设置为debug模式, 如果值为true则可以查看详细的发送 log // 3. 创建一封邮件 MimeMessage message = createMimeMessage(session, myEmailAccount, receiveMailAccount); // 4. 根据 Session 获取邮件传输对象 Transport transport = session.getTransport(); // 5. 使用 邮箱账号 和 密码 连接邮件服务器--这里认证的邮箱必须与 message 中的发件人邮箱一致,否则报错 transport.connect(myEmailAccount, myEmailPassword); // 6. 发送邮件, 发到所有的收件地址, message.getAllRecipients() 获取到的是在创建邮件对象时添加的所有收件人, 抄送人, 密送人 transport.sendMessage(message, message.getAllRecipients()); // 7. 关闭连接 transport.close(); } /** * 创建一封只包含文本的简单邮件 * * @param session 和服务器交互的会话 * @param sendMail 发件人邮箱 * @param receiveMail 收件人邮箱 * @return * @throws Exception */ public static MimeMessage createMimeMessage(Session session, String sendMail, String receiveMail) throws Exception { // 1. 创建一封邮件 MimeMessage message = new MimeMessage(session); // 2. From: 发件人 message.setFrom(new InternetAddress(sendMail, "mabiao008", "UTF-8")); // 3. To: 收件人(可以增加多个收件人、抄送、密送) message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(receiveMail, "测试", "UTF-8")); // 4. Subject: 邮件主题 message.setSubject("测试邮件", "UTF-8"); // 5. Content: 邮件正文(可以使用html标签) message.setContent("<font color=\"red\">欢迎光临我的博客: http://www.cnblogs.com/mabiao008/ </font>", "text/html;charset=UTF-8"); // 6. 设置发件时间 message.setSentDate(new Date()); // 7. 保存设置 message.saveChanges(); return message; } }
方式2:
需要3个java文件支持
