java邮件发送

1.邮件信息封装bean

package com.mail;

import java.util.Properties;
/**
 * @desc 设置邮件基本信息
 */
public class MailInfo {
	// 发送邮件的服务器的IP和端口[大多默认为25，gmail：465]

	//是否需要身份验证　
	private boolean validate = false;
	//邮件主题⡡ 
	private String subject;
	// 邮件的文本内容　
	private String content;
	// 邮件附件的文件名[上传文件路径]

	/** 
	 * 获得邮件会话属性　　 
	 */

	}

	public void setContent(String textContent) {

	}
}

2.邮件发送器

package com.mail;

import java.util.Date;
import java.util.Properties;
import javax.activation.DataHandler;
import javax.activation.FileDataSource;
import javax.mail.Address;
import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

/**
 * 简单邮件（不带附件的邮件）发送器
 */
public class SendMail {
	/**
	 * 以文本格式发送邮件
	 * @param mailInfo
	 * 待发送的邮件的信息
	 */
	public boolean sendTextMail(MailInfo mailInfo) {
		// 判断是否需要身份认证
		MyAuthenticator authenticator = null;
		Properties pro = mailInfo.getProperties();
		if (mailInfo.isValidate()) {
			// 如果需要身份认证，则创建一个密码验证器
			authenticator = new MyAuthenticator(mailInfo.getUserName(),mailInfo.getPassword());
		}
		// 根据邮件会话属性和密码验证器构造一个发送邮件的session
		Session sendMailSession = Session.getDefaultInstance(pro,authenticator);
		try {
			//根据session创建一个邮件消息
			Message mailMessage = new MimeMessage(sendMailSession);
			//创建邮件发送者地址

			String []toArray=mailInfo.getToAddress();

			InternetAddress[] toAddrArray = new InternetAddress[toArray.length];  
			for (int i = 0; i < toArray.length; i++) {
				toAddrArray[i] = new InternetAddress(toArray[i]);
			}
			mailMessage.setRecipients(Message.RecipientType.TO, toAddrArray);
			//设置邮件消息的主题

			//设置邮件消息发送的时间
			mailMessage.setSentDate(new Date());
			//设置邮件消息的主要内容
			String mailContent = mailInfo.getContent();
			mailMessage.setText(mailContent);
			//发送邮件
			Transport.send(mailMessage);
			return true;
		} catch (MessagingException ex) {
			ex.printStackTrace();
		}
		return false;
	}
	  /**

		return false;
	}
	 /**

	public static boolean sendAttach(MailInfo mailInfo) {

			Transport.send(mailMessage);
			return true;
		} catch (MessagingException ex) {
			ex.printStackTrace();
		}
		return false;
	}
}

3.身份认证

package com.mail;

import javax.mail.*;

public class MyAuthenticator extends Authenticator {
	private String username = "";
	private String password = "";

	public MyAuthenticator() {
	}

	public MyAuthenticator(String username, String password) {
		this.username = username;
		this.password = password;
	}

	protected PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication(username, password);
	}

}

4.测试使用

package com.mail;

public class TestMail {
	
	public static void main(String[] args) {
		MailInfo mailinfo=new MailInfo();
		//--设置邮件服务器开始
		mailinfo.setMailServerHost("smtp.gmail.com");
		mailinfo.setMailServerPort("465");
		mailinfo.setValidate(true);
		mailinfo.setUserName("zhaozhi3758");
		mailinfo.setPassword("XXXXXXXX");
		//--设置邮件服务器结束
		mailinfo.setFromAddress("[e-mail]");//邮件发送者的地址
		//设置接受用户
		String []ToAddress={"[e-mail]"};
		mailinfo.setToAddress(ToAddress);
		//设置附件
		String []attach={"F:\\login.properties"};
		mailinfo.setAttachFileNames(attach);
		mailinfo.setSubject("-----邮件测试----");
		mailinfo.setContent("<a href='#'>hiao的和</a>");//网页内容
		SendMail sm=new SendMail();
		if(sm.sendAttach(mailinfo))
			System.out.println("邮件发送成功");
		else
			System.out.println("邮件发送失败");
		
	}

}

sendAttach方法

4 楼 qiushily2030 2010-11-26  

楼主,附件为word文档  文件名会出现乱码 
如：邋_鰢w-20101125.doc
这个如何解决？

3 楼 weijavamen 2010-11-19  

很不错，很实用

2 楼 hoary20 2010-09-19  

如果是多个附件的时候该怎么处理呢？

1 楼 lency 2010-09-03  

非常感谢，可以用，如果能把activation.jar mail.jar两个包放上去供大家下载就更好了。
