JavaMail邮件发送-发送一个文本邮件和一些问题说明

 

需要下载的JAR包：

JavaMail：http://www.oracle.com/technetwork/java/javamail/index.html 

JAF：http://www.oracle.com/technetwork/java/javase/downloads/index-135046.html 

加入的包有：mail.jar activation.jar

 

你要准备一个邮箱账户，就用网易的吧，然后打开SMTP功能

 

 

 

 

 

关于网易的一些端口信息参考下面：

 

 

 每个公司都是不一样的，使用SSL的和不实用的也不一样

 

 使用的开发和编译环境是JDK1.4，如果你使用的是JDK1.5环境，那么你的环境需要修改一些东西，找到 javaee.jar 删除里面的 mial 包，否则会有冲突

 

否则会报错：

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream

 下面我直接贴代码了

package com.mail;

 import java.util.Properties;
 import javax.mail.Message;
 import javax.mail.Session;
 import javax.mail.Transport;
 import javax.mail.internet.InternetAddress;

 // 如果你使用JDK1.4以上运行 会出现 Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
 // 需要你找到 javaee.jar 删掉 里面的 mail 包
 public class TextMail {
     public static void main(String[] args) throws Exception {
         // 配置文件对象
         Properties props = new Properties();
         // 邮箱服务地址
         props.put( "mail.smtp.host ", "smtp.163.com ");
         // 是否进行验证
         props.put("mail.smtp.auth", "true");
         // 创建一个会话
        Session session = Session.getInstance(props);
         // 打开调试，会打印与邮箱服务器回话的内容
         session.setDebug(true);
         Message message = new MimeMessage(session);
         // 如果发送人没有写对，那么会出现 javamail 550 Invalid User
         // 如果发送人写的和使用的帐号不一致，则会出现 553 Mail from must equal authorized user
         InternetAddress from = new InternetAddress("[email protected]");
         from.setPersonal(MimeUtility.encodeText("java小强<[email protected]>"));
        message.setFrom(from);
         InternetAddress to = new InternetAddress("[email protected]");
        message.setRecipient(Message.RecipientType.TO, to);
         message.setSubject(MimeUtility.encodeText("强哥邀请，谁敢不从！"));
         message.setText("强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！");
         message.setSentDate(new Date());
         Transport transport = session.getTransport("smtp");
         // 具体你使用邮箱的smtp地址和端口，应该到邮箱里面查看，如果使用了SSL，网易的端口应该是 465/994
         transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");
        transport.sendMessage(message, message.getAllRecipients());
        transport.close();
         System.out.println("发送完毕");
    }
}

package com.mail;
import java.util.Date;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;
// 如果你使用JDK1.4以上运行 会出现 Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream
// 需要你找到 javaee.jar 删掉 里面的 mail 包
public class TextMail {
	public static void main(String[] args) throws Exception {
		// 配置文件对象
		Properties props = new Properties();
		// 邮箱服务地址
		props.put( "mail.smtp.host ", "smtp.163.com ");		
		// 是否进行验证
		props.put("mail.smtp.auth", "true");
		// 创建一个会话
		Session session = Session.getInstance(props);
		// 打开调试，会打印与邮箱服务器回话的内容
		session.setDebug(true);
		Message message = new MimeMessage(session);
		// 如果发送人没有写对，那么会出现 javamail 550 Invalid User
		// 如果发送人写的和使用的帐号不一致，则会出现 553 Mail from must equal authorized user
		InternetAddress from = new InternetAddress("[email protected]");
		from.setPersonal(MimeUtility.encodeText("java小强<[email protected]>"));
		message.setFrom(from);
		InternetAddress to = new InternetAddress("[email protected]");
		message.setRecipient(Message.RecipientType.TO, to);
		message.setSubject(MimeUtility.encodeText("强哥邀请，谁敢不从！"));
		message.setText("强哥邀请你访问我的博客：http://cuisuqiang.iteye.com/！");
		message.setSentDate(new Date());
		Transport transport = session.getTransport("smtp");
		// 具体你使用邮箱的smtp地址和端口，应该到邮箱里面查看，如果使用了SSL，网易的端口应该是 465/994
		transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");
		transport.sendMessage(message, message.getAllRecipients());
		transport.close();
		System.out.println("发送完毕");
	}
}

 

需要注意的有

InternetAddress from = new InternetAddress("[email protected]");

InternetAddress from = new InternetAddress("[email protected]");

 

和

transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");

transport.connect("smtp.163.com", 25, "test20120711120200", "test123456");

 

这两个邮箱的地址必须相同，否则会出现

Exception in thread "main" javax.mail.MessagingException: 553 Mail from must equal authorized user

     at com.sun.mail.smtp.SMTPTransport.issueCommand(SMTPTransport.java:1020)
     at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:716)
     at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:388)
     at com.mail.TextMail.main(TextMail.java:38)

Exception in thread "main" javax.mail.MessagingException: 553 Mail from must equal authorized user

	at com.sun.mail.smtp.SMTPTransport.issueCommand(SMTPTransport.java:1020)
	at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:716)
	at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:388)
	at com.mail.TextMail.main(TextMail.java:38)

 

你上网查都是说用户验证不对，其实一般大家都是按照别人代码拷贝的，然后修改了用户和密码，怎么会不对！

我这个账户和密码都是可以用的，对不起网易了！

 

由于上面我设置了打印调试，所以你在控制台会看到如下内容：

这些都是程序与邮件服务商的一些交互信息！
