使用java发送邮件的时候,需要先下载两个jar包,连接如下:
然后将这连个包导入,博主用的是IDEA,导包的教程连接:https://www.cnblogs.com/yulia/p/6824058.html
由于QQ邮箱需要SSL加密,这个需要在自己的QQ邮箱中设置然后进行提取密码:
获取这么密码以后:
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 void main(String [] args) throws GeneralSecurityException { // 收件人电子邮箱 String to = "XXXXX@qq.com"; // 发件人电子邮箱 String from = "XXXXXX@qq.com"; // 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("发送人的邮箱", "授权的 QQ 邮箱密码"); //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("This is the Subject Line!"); // 设置消息体 message.setText("This is actual message"); // 发送消息 Transport.send(message); System.out.println("Sent message successfully....from runoob.com"); }catch (MessagingException mex) { mex.printStackTrace(); } } }
不会的可以加本人好友共同探讨一下
