在java版經(jīng)常看到有人問如何用javamail發(fā)送郵件？如何接收郵件？如何訪問多個文件夾等。問題零散，而歷史的回復(fù)早已經(jīng)淹沒在問題的海洋之中。
本人之前所做過一個java項目，其中包含有WebMail功能，當(dāng)初為用java實現(xiàn)而對javamail摸索了一段時間，總算有點收獲。看到論壇中的經(jīng)常有此方面的問題，因此把我的一些經(jīng)驗帖出來，希望對大家有些幫助。
此篇僅介紹用javamail實現(xiàn)發(fā)送郵件功能，其中涉及smtp認(rèn)證，郵件附件發(fā)送，及HTML內(nèi)容郵件等。
其它有關(guān)多郵箱的實現(xiàn)，接收POP3郵件及IMAP等內(nèi)容，將在后續(xù)文章中介紹。
如下程序需要：javamail，JAF包，j2ee.jar包含了上述兩個包，建議大家安裝J2SDKEE或直接拷貝j2ee.jar，將其添加到j(luò)builder的library中，或系統(tǒng)ClassPath中

我是按照weblogic公司的幫助文檔做的。不知還要配置什么？
1. 通過console方式創(chuàng)建一個MailSession.
2. 在Configuration欄中輸入以下參數(shù)：
Name: MyMailSession
JNDIName: MyMailSession
Properties
mail.smtp.host=winqiu
3. 然后在Targets欄中將mailsession加入你的Target Servers.
4. 這樣你的mailsession就創(chuàng)建成功了.
5. 在程序中調(diào)用的方法如下：
import java.util.*;
import javax.activation.*;
import javax.mail.Session;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
public class SendMail {
Context ic = null;
public SendMail() {
}
public void send() {
//使用JNDI查詢Mail Session，
try
{
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://winqiu:7001");
ic = new InitialContext(ht);
Session session = (Session) ic.lookup("myMailSession");
//設(shè)置屬性，然后創(chuàng)建Session實例
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "winqiu");
InternetAddress emailAddress = new InternetAddress(
"win_qiu@yahoo.com.cn");
props.put("mail.from", emailAddress);
Session session2 =session.getInstance(props);
//創(chuàng)建消息
Message msg = new MimeMessage(session2);
msg.setFrom();
String to = "win_qiu@hotmail.com.cn";
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to, false));
String subject = "hello";
msg.setSubject(subject);
msg.setSentDate(new Date());
// 將消息內(nèi)容存放到MimeBodyPart對象中，然后把MimeBodyPart對象
//存入Multipart對象中，最后，把代表附件的Multipart對象加入待
//發(fā)送的消息中
MimeBodyPart mbp = new MimeBodyPart();
String messageTxt = "first mail ";
mbp.setText(messageTxt);
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);
msg.saveChanges();
//發(fā)送消息
Transport.send(msg);
}
catch (NamingException e) {
e.printStackTrace();
}
catch (MessagingException e) {
e.printStackTrace();
}
}
public static void main(String args[])
{
SendMail sendMail=new SendMail();
sendMail.send();
System.out.println("send ok");
}
}
但是我的發(fā)送郵件時候就出現(xiàn)這樣的異常：
