注意一下:

Myeclipse自帶的JavaEE5.jar和java?mail會(huì)發(fā)生沖突

找到ME下的javeee包

D:\MyEclipse?8.5\Common\plugins\com.genuitec.eclipse.j2eedt.core_8.5.0.me201003231033\data\libraryset\EE_5\javaee.jar

用rar等解壓工具解開(kāi)javaee.jar,刪除里面的javax\mail文件夾(可以先備份javaee.jar)

也即,以后都不能使用javaee.jar里面的郵件api發(fā)送郵件了.

求java實(shí)現(xiàn)郵件發(fā)送的源代碼

import java.util.*;

import javax.mail.*;import javax.mail.internet.*;

public class JMail {

public void SendMail(String Topic,String Content){ Properties props=new Properties(); props.put("mail.smtp.host","smtp.163.com"); props.put("mail.smtp.auth","true"); Session s=Session.getInstance(props); s.setDebug(false); MimeMessage message=new MimeMessage(s); MimeMultipart mp=new MimeMultipart(); BodyPart body = new MimeBodyPart(); InternetAddress from; InternetAddress to; try{ from=new InternetAddress("發(fā)件人郵箱"); message.setFrom(from); to = new InternetAddress("收件人郵箱"); message.setRecipient(Message.RecipientType.TO,to); message.setSubject(Topic,"utf-8"); body.setContent(Content, "text/html;charset=utf-8"); mp.addBodyPart(body); message.setContent(mp); message.setSentDate(new Date()); message.saveChanges(); Transport transport=s.getTransport("smtp"); transport.connect("smtp.163.com(郵件服務(wù)商，這是163的)","發(fā)件郵箱","發(fā)件郵箱密碼"); transport.sendMessage(message,message.getAllRecipients()); transport.close(); } catch(AddressException e){ e.printStackTrace(); } catch(MessagingException e){ e.printStackTrace(); } }}

用java寫(xiě)一個(gè)郵件發(fā)送代碼

public boolean mainto()

{

boolean flag = true;

//建立郵件會(huì)話

Properties pro = new Properties();

pro.put("mail.smtp.host","smtp.qq.com");//存儲(chǔ)發(fā)送郵件的服務(wù)器

pro.put("mail.smtp.auth","true"); //通過(guò)服務(wù)器驗(yàn)證

Session s =Session.getInstance(pro); //根據(jù)屬性新建一個(gè)郵件會(huì)話

//s.setDebug(true);

//由郵件會(huì)話新建一個(gè)消息對(duì)象

MimeMessage message = new MimeMessage(s);

//設(shè)置郵件

InternetAddress fromAddr = null;

InternetAddress toAddr = null;

try

{

fromAddr = new InternetAddress(451144426+"@qq.com"); //郵件發(fā)送地址

message.setFrom(fromAddr); //設(shè)置發(fā)送地址

toAddr = new InternetAddress("12345367@qq.com"); //郵件接收地址

message.setRecipient(Message.RecipientType.TO, toAddr); //設(shè)置接收地址

message.setSubject(title); //設(shè)置郵件標(biāo)題

message.setText(content); //設(shè)置郵件正文

message.setSentDate(new Date()); //設(shè)置郵件日期

message.saveChanges(); //保存郵件更改信息

Transport transport = s.getTransport("smtp");

transport.connect("smtp.qq.com", "451144426", "密碼"); //服務(wù)器地址，郵箱賬號(hào)，郵箱密碼

transport.sendMessage(message, message.getAllRecipients()); //發(fā)送郵件

transport.close();//關(guān)閉

}

catch (Exception e)

{

e.printStackTrace();

flag = false;//發(fā)送失敗

}

return flag;

}

這是一個(gè)javaMail的郵件發(fā)送代碼，需要一個(gè)mail.jar

如何在 java 發(fā)郵件中提供鏈接？

代碼如下：

import java.util.Properties;

import javax.mail.Authenticator;

import javax.mail.Message;

import javax.mail.Message.RecipientType;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class EmailTest {

public static void main(String[] args) throws Exception{

Properties props = new Properties();

props.setProperty("mail.smtp.auth", "true");

props.setProperty("mail.transport.protocol", "smtp");

props.setProperty("mail.host", "smtp.163.com");

Session session = Session.getInstance(props,

new Authenticator() {

protected PasswordAuthentication getPasswordAuthentication(){

return new PasswordAuthentication("xxx","xxx");//這里分別填寫(xiě)發(fā)送email的用戶名、密碼

}

}

);

session.setDebug(true);

Message msg = new MimeMessage(session);

msg.setFrom(new InternetAddress("xxx"));//這里是發(fā)送方的email地址如：xxx@163.com

msg.setSubject("test javamail");

msg.setRecipients(RecipientType.TO,

InternetAddress.parse("xxx"));//這里是接收方的email地址如：xxx@163.com

msg.setContent("a href=\"\"谷歌/a","text/html;charset=gb2312");

Transport.send(msg);

}

}
