(转)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：

Java代码


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

at javax.mail.Session.loadProvidersFromStream(Session.java:928)

at javax.mail.Session.access$000(Session.java:174)

at javax.mail.Session$1.load(Session.java:870)

at javax.mail.Session.loadResource(Session.java:1084)

at javax.mail.Session.<init>(Session.java:210)

at javax.mail.Session.getInstance(Session.java:249)

at com.mail.TextMail.main(TextMail.java:22)

下面我直接贴代码了

Java代码


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("test20120711120200@163.com");

from.setPersonal(MimeUtility.encodeText("java小强<test20120711120200@163.com>"));

message.setFrom(from);

InternetAddress to = new InternetAddress("455213313@qq.com");

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

Java代码


InternetAddress from = new InternetAddress("test20120711120200@163.com");

和

Java代码


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

Java代码


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：

Java代码

这些都是程序与邮件服务商的一些交互信息！
