java发邮件源码

❶ java实现发送邮件功能

要实现邮件发送功能需要导入包：mail.jar

/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package org.demo.action;

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.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.demo.form.DemoForm;

public class DemoAction extends Action {

private static final String CONTENT_TYPE = "test/html;charset=GB2312";

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DemoForm demoForm = (DemoForm) form;
System.out.println("标题是" + demoForm.getBiaoti());
System.out.println("内容是" + demoForm.getNeirong());
try {
response.setContentType(CONTENT_TYPE);
String smtphost = "smtp.nj.headware.cn"; // 发送邮件服务器
String user = "q0000015369"; // 邮件服务器登录用户名
String password = "Queshuwen26"; // 邮件服务器登录密码
String from = "[email protected]"; //
String to = "[email protected]"; // 收件人邮件地址
String subject = demoForm.getBiaoti(); // 邮件标题
String body = demoForm.getNeirong(); // 邮件内容
Properties props = new Properties();
props.put("mail.smtp.host", smtphost);
props.put("mail.smtp.auth", "true");
Session ssn = Session.getInstance(props, null);

MimeMessage message = new MimeMessage(ssn);

InternetAddress fromAddress = new InternetAddress(from);
message.setFrom(fromAddress);
InternetAddress toAddress = new InternetAddress(to);
message.addRecipient(Message.RecipientType.TO, toAddress);
message.setSubject(subject);
message.setText(body);
Transport transport = ssn.getTransport("smtp");

transport.connect(smtphost, user, password);

transport.sendMessage(message, message
.getRecipients(Message.RecipientType.TO));
// transport.send(message);
transport.close();
return mapping.findForward("succ");
} catch (Exception e) {
e.printStackTrace();
return mapping.findForward("fail");
}

}
}

❷ 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("[email protected]"); //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

❸ 如何使用Java发送qq邮件

方法:

1.前提准备工作：
首先，邮件的发送方要开启POP3 和SMTP服务--即发送qq邮件的账号要开启POP3 和SMTP服务

2.开启方法：
登陆qq邮箱
3.点击 设置

4.点击—-账户

5.找到：POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务 —点击开启

6.送短信 —–点击确定

7.稍等一会，很得到一个授权码！ –注意：这个一定要记住，一会用到

8.点击保存修改 —OK 完成

9.java 测试代码：
package cn.cupcat.test;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;
public class SendmailUtil {
public static void main(String[] args) throws AddressException, MessagingException {

Properties properties = new Properties();
properties.put("mail.transport.protocol", "smtp");// 连接协议
properties.put("mail.smtp.host", "smtp.qq.com");// 主机名
properties.put("mail.smtp.port", 465);// 端口号
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.ssl.enable", "true");//设置是否使用ssl安全连接 ---一般都使用
properties.put("mail.debug", "true");//设置是否显示debug信息 true 会在控制台显示相关信息
//得到回话对象
Session session = Session.getInstance(properties);
// 获取邮件对象
Message message = new MimeMessage(session);
//设置发件人邮箱地址
message.setFrom(new InternetAddress("[email protected]"));
//设置收件人地址 message.setRecipients( RecipientType.TO, new InternetAddress[] { new InternetAddress("[email protected]") });
//设置邮件标题
message.setSubject("这是第一封Java邮件");
//设置邮件内容
message.setText("内容为： 这是第一封java发送来的邮件。");
//得到邮差对象
Transport transport = session.getTransport();
//连接自己的邮箱账户
transport.connect("[email protected]", "vvctybgbvvophjcj");//密码为刚才得到的授权码
//发送邮件 transport.sendMessage(message, message.getAllRecipients());
}
}
10.运行就会发出邮件了。。。。
下面是我收到邮件的截图，当然我把源码中的邮件地址都是修改了，不是真实的，你们测试的时候，可以修改能你们自己的邮箱。最后，祝你也能成功，如果有什么问题，可以一起讨论！

注意事项

得到的授权码一定要保存好，程序中要使用

❹ 急java 发送邮件 急！~急！~ 高手快进来帮忙看看啊！~

这是我的连续发几封邮件的代码。连续发是为了163邮箱的积分，^_^。你可以参考下。
package com.test;

import java.io.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;

public class SendEmail extends Authenticator {
public static final String mailuser = "xianlaioy"; // 需要你的邮箱帐号(仅@符号前面的)
public static final String password = "######"; // 需要你的邮箱密码
private Properties props;

public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(mailuser, password);
}

public SendEmail(){
props = new Properties();
InputStream is = null;
try {
/*当部署在web容器中时，路径要修改
* Thread.currentThread().getContextClassLoader().getResource("").getPath();
* 得到的url是web容器中的项目下的class路径
**/

is = new FileInputStream("src/sendemail.properties");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
try {
props.load(is);
} catch (IOException e) {
e.printStackTrace();
}

}

/** email为接收邮箱，text为邮件正文
* @throws IOException */
public void sendEamils(String email, String text) throws IOException {
Transport transport = null;
try {
props.setProperty("mail.smtp.host", props.getProperty("mail.smtp.host"));
props.setProperty("mail.smtp.auth", props.getProperty("mail.smtp.auth"));
SendEmail auth = new SendEmail();
javax.mail.Session session = javax.mail.Session.getDefaultInstance(props,
auth);
MimeMessage message = new MimeMessage(session);
Address addressFrom = new InternetAddress(SendEmail.mailuser
+ "@163.com", "欧阳");
Address addressTo = new InternetAddress(email, "xianlai");

message.setText(text);
message.setSubject("邮件标题");
message.setFrom(addressFrom);
message.addRecipient(Message.RecipientType.TO, addressTo);

message.saveChanges();
transport = session.getTransport("smtp");
session.setDebug(true);

/*transport.connect("smtp.126.com", SendEmail.mailuser,
SendEmail.password);*/

transport.send(message);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} finally {
if (transport != null) {
try {
transport.close();
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
}

public static void main(String[] args) {

Timer t = new Timer();
long delay =2*60*1000;
t.schele(new TimerTask(){
private int count=0;
private SendEmail se=new SendEmail();//作为成员变量就只会创建一个SendEmail对象。

public void run() {
//在timer的run中就必须考虑好怎样或者什么时候退出的问题。
//这里是用count计数的方法来考虑退出的问题的。
if(count++<1){
int i=10;
for (int j = 0; j < i; j++) {
try {
se.sendEamils("[email protected]","test"+j );
} catch (IOException e) {
e.printStackTrace();
}
}
}else {
this.cancel();
System.exit(0);
}
}}, 2000,delay);

}
}

❺ 怎样用java实现邮件的发送

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.SocketException;
import java.rmi.UnknownHostException;
import java.util.StringTokenizer;

import sun.misc.BASE64Encoder;

public class Sender {
//private boolean debug = true;
BASE64Encoder encode=new BASE64Encoder();//用于加密后发送用户名和密码
static int dk=25;

private Socket socket;

public Sender(String server, int port) throws UnknownHostException,
IOException {
try {
socket = new Socket(server, dk);
} catch (SocketException e) {
System.out.println(e.getMessage());
} catch (Exception e) {
e.printStackTrace();
} finally {
//System.out.println("已经建立连接!");
}

}

// 注册到邮件服务器
public void helo(String server, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = getResult(in);
// 连接上邮件服务后,服务器给出220应答
if (result != 220) {
throw new IOException("连接服务器失败");
}
result = sendServer("HELO " + server, in, out);
// HELO命令成功后返回250
if (result != 250) {
throw new IOException("注册邮件服务器失败！");
}
}

private int sendServer(String str, BufferedReader in, BufferedWriter out)
throws IOException {
out.write(str);
out.newLine();
out.flush();
/*
if (debug) {
System.out.println("已发送命令:" + str);
}
*/
return getResult(in);
}

public int getResult(BufferedReader in) {
String line = "";
try {
line = in.readLine();
/*
if (debug) {
System.out.println("服务器返回状态:" + line);
}
*/
} catch (Exception e) {
e.printStackTrace();
}
// 从服务器返回消息中读出状态码,将其转换成整数返回

StringTokenizer st = new StringTokenizer(line, " ");
return Integer.parseInt(st.nextToken());
}

public void authLogin(MailMessage message, BufferedReader in,
BufferedWriter out) throws IOException {
int result;
result = sendServer("AUTH LOGIN", in, out);

if (result != 334) {
throw new IOException("用户验证失败！");
}

result=sendServer(encode.encode(message.getUser().getBytes()),in,out);
//System.out.println("用户名： "+encode.encode(message.getUser().getBytes()));
if (result != 334) {
throw new IOException("用户名错误！");
}
result=sendServer(encode.encode(message.getPassword().getBytes()),in,out);
//result=sendServer(message.getPassword(),in,out);
//System.out.println("密码： "+encode.encode(message.getPassword().getBytes()));
if (result != 235) {
throw new IOException("验证失败！");
}
}

// 开始发送消息，邮件源地址
public void mailfrom(String source, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("MAIL FROM:<" + source + ">", in, out);
if (result != 250) {
throw new IOException("指定源地址错误");
}
}

// 设置邮件收件人
public void rcpt(String touchman, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = sendServer("RCPT TO:<" + touchman + ">", in, out);
if (result != 250) {
throw new IOException("指定目的地址错误！");
}
}

// 邮件体
public void data(String from, String to, String subject, String content,
BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("DATA", in, out);
// 输入DATA回车后,若收到354应答后,继续输入邮件内容
if (result != 354) {
throw new IOException("不能发送数据");
}
out.write("From: " + from);
out.newLine();
out.write("To: " + to);
out.newLine();
out.write("Subject: " + subject);
out.newLine();
out.newLine();
out.write(content);
out.newLine();
// 句号加回车结束邮件内容输入
result = sendServer(".", in, out);
//System.out.println(result);
if (result != 250) {
throw new IOException("发送数据错误");
}
}

// 退出
public void quit(BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("QUIT", in, out);
if (result != 221) {
throw new IOException("未能正确退出");
}
}

// 发送邮件主程序
public boolean sendMail(MailMessage message, String server) {
try {
BufferedReader in = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream()));
helo(server, in, out);// HELO命令
authLogin(message, in, out);// AUTH LOGIN命令
mailfrom(message.getFrom(), in, out);// MAIL FROM
rcpt(message.getTo(), in, out);// RCPT
data(message.getDatafrom(), message.getDatato(),
message.getSubject(), message.getContent(), in, out);// DATA
quit(in, out);// QUIT
} catch (Exception e) {
e.printStackTrace();
return false;

}
return true;
}
}
再写一个MailMessage.java，set/get方法即可。

❻ 用java写收发邮件的程序，求助，在线

import java.util.Properties;
import java.util.Date;
import javax.mail.Session;
import javax.mail.Message;
import javax.mail.Transport;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.InternetAddress;

public class HelloWorldJavaMail {
public static void main(String[] args) {
try {
Properties props = System.getProperties();
props.put("mail.smtp.host","xxx.xxx.xxx.xxx");
Session session=Session.getDefaultInstance(props,null);
MimeMessage mimeMessage=new MimeMessage(session);
mimeMessage.setFrom(new InternetAddress("[email protected]","姓名","gb2312"));
mimeMessage.setRecipients(Message.RecipientType.TO,"[email protected]");
mimeMessage.setSubject("Hello World JavaMail","gb2312");
mimeMessage.setText("<h1>Hello World JavaMail</h1>","gb2312");
mimeMessage.setHeader("Content-Type","text/html");
mimeMessage.setSentDate(new Date());
Transport.send(mimeMessage);
} catch (Exception e) {
e.printStackTrace();
}
}
}

2。收信
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class HelloWorldPOP {
public static void main(String args[]) {
try {
String host="xxx.xxx.xxx.xxx";
String user="xxxxxx";
String password="xxxxxx";

Session session = Session.getDefaultInstance(System.getProperties(), null);
Store store = session.getStore("pop3");
store.connect(host, -1, user, password);

Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);

int totalMessages = folder.getMessageCount();
if (totalMessages == 0) {
System.out.println("没有邮件");
folder.close(false);
store.close();
return;
}

Message[] messages = folder.getMessages();
for (int i = 0; i < messages.length; i++) {
showMessage(messages[i]);
}

folder.close(false);
store.close();
} catch (Exception e) {
e.printStackTrace();
}
}

public static void showMessage(Message m) throws Exception {
Address[] a;
if ((a = m.getFrom())!=null) {
for (int j = 0; j < a.length; j++) {
System.out.println("送信人: " + MimeUtility.decodeText(a[j].toString()));
}
}

if ((a = m.getRecipients(Message.RecipientType.TO))!=null) {
for (int j = 0; j < a.length; j++) {
System.out.println("收信人: " + MimeUtility.decodeText(a[j].toString()));
}
}

System.out.println("主体: " + m.getSubject());
Date d = m.getSentDate();
System.out.println("日期: " + (d!= null ? d.toString() : "不明"));
System.out.println("大小: " + m.getSize());
System.out.println("内容：\n" + m.getContent());
}
}

用JAVAMAIL很容易实现的。
