网上javaMail邮箱推送代码太多，大都是有缺陷的，今天做项目刚好要用到，于是发了大半天的时间解决的这个问题。
jar包：javax.mail.jar
代码：
1 import java.io.IOException; 2 import java.security.GeneralSecurityException; 3 import java.util.Date; 4 import java.util.Properties; 5 6 import javax.mail.Message.RecipientType; 7 import javax.mail.Authenticator; 8 import javax.mail.Message; 9 import javax.mail.MessagingException;10 import javax.mail.NoSuchProviderException;11 import javax.mail.PasswordAuthentication;12 import javax.mail.Session;13 import javax.mail.Transport;14 import javax.mail.internet.AddressException;15 import javax.mail.internet.InternetAddress;16 import javax.mail.internet.MimeMessage;17 18 19 20 public class EmailPushUtil {21 public static void main(String[] args) {22 boolean isSSL = true;23 String host = "";24 int port = 465;25 String from = " ";//发送者邮箱26 String to = " ";//接收者邮箱27 boolean isAuth = true;28 final String username = " ";//发送者账号29 final String password = " ";//密码30 31 Properties props = new Properties();32 props.put("mail.smtp.ssl.enable", isSSL);33 props.put("mail.smtp.host", host);34 props.put("mail.smtp.port", port);35 props.put("mail.smtp.auth", isAuth);36 37 Session session = Session.getDefaultInstance(props, new Authenticator() {38 @Override39 protected PasswordAuthentication getPasswordAuthentication() {40 return new PasswordAuthentication(username, password);41 }42 });43 44 try {45 Message message = new MimeMessage(session);46 47 message.setFrom(new InternetAddress(from));48 message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));49 message.setSubject("主题");50 message.setText("内容");51 52 Transport.send(message);53 } catch (AddressException e) {54 e.printStackTrace();55 } catch (MessagingException e) {56 e.printStackTrace();57 }58 59 System.out.println("发送完毕！");60 }61 }
