(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:
- 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.loadProviders(Session.java:889)
- 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
- 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
- InternetAddress from = new InternetAddress("test20120711120200@163.com");
和
- 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)
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!
