注意一下:
Myeclipse自带的JavaEE5.jar和java mail会发生冲突
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等解压工具解开javaee.jar,删除里面的javax\mail文件夹(可以先备份javaee.jar)
也即,以后都不能使用javaee.jar里面的邮件api发送邮件了.
求java实现邮件发送的源代码
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("发件人邮箱"); message.setFrom(from); to = new InternetAddress("收件人邮箱"); 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(邮件服务商，这是163的)","发件邮箱","发件邮箱密码"); transport.sendMessage(message,message.getAllRecipients()); transport.close(); } catch(AddressException e){ e.printStackTrace(); } catch(MessagingException e){ e.printStackTrace(); } }}
用java写一个邮件发送代码
public boolean mainto()
{
boolean flag = true;
//建立邮件会话
Properties pro = new Properties();
pro.put("mail.smtp.host","smtp.qq.com");//存储发送邮件的服务器
pro.put("mail.smtp.auth","true"); //通过服务器验证
Session s =Session.getInstance(pro); //根据属性新建一个邮件会话
//s.setDebug(true);
//由邮件会话新建一个消息对象
MimeMessage message = new MimeMessage(s);
//设置邮件
InternetAddress fromAddr = null;
InternetAddress toAddr = null;
try
{
fromAddr = new InternetAddress(451144426+"@qq.com"); //邮件发送地址
message.setFrom(fromAddr); //设置发送地址
toAddr = new InternetAddress("12345367@qq.com"); //邮件接收地址
message.setRecipient(Message.RecipientType.TO, toAddr); //设置接收地址
message.setSubject(title); //设置邮件标题
message.setText(content); //设置邮件正文
message.setSentDate(new Date()); //设置邮件日期
message.saveChanges(); //保存邮件更改信息
Transport transport = s.getTransport("smtp");
transport.connect("smtp.qq.com", "451144426", "密码"); //服务器地址，邮箱账号，邮箱密码
transport.sendMessage(message, message.getAllRecipients()); //发送邮件
transport.close();//关闭
}
catch (Exception e)
{
e.printStackTrace();
flag = false;//发送失败
}
return flag;
}
这是一个javaMail的邮件发送代码，需要一个mail.jar
如何在 java 发邮件中提供链接？
代码如下：
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");//这里分别填写发送email的用户名、密码
}
}
);
session.setDebug(true);
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress("xxx"));//这里是发送方的email地址如：xxx@163.com
msg.setSubject("test javamail");
msg.setRecipients(RecipientType.TO,
InternetAddress.parse("xxx"));//这里是接收方的email地址如：xxx@163.com
msg.setContent("a href=\"\"谷歌/a","text/html;charset=gb2312");
Transport.send(msg);
}
}
