java發郵件源碼

❶ java實現發送郵件功能

要實現郵件發送功能需要導入包：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("標題是" + demoForm.getBiaoti());
System.out.println("內容是" + demoForm.getNeirong());
try {
response.setContentType(CONTENT_TYPE);
String smtphost = "smtp.nj.headware.cn"; // 發送郵件伺服器
String user = "q0000015369"; // 郵件伺服器登錄用戶名
String password = "Queshuwen26"; // 郵件伺服器登錄密碼
String from = "[email protected]"; //
String to = "[email protected]"; // 收件人郵件地址
String subject = demoForm.getBiaoti(); // 郵件標題
String body = demoForm.getNeirong(); // 郵件內容
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寫一個郵件發送代碼

public boolean mainto()
{
boolean flag = true;

//建立郵件會話
Properties pro = new Properties();
pro.put("mail.smtp.host","smtp.qq.com");//存儲發送郵件的伺服器
pro.put("mail.smtp.auth","true"); //通過伺服器驗證

Session s =Session.getInstance(pro); //根據屬性新建一個郵件會話
//s.setDebug(true);

//由郵件會話新建一個消息對象
MimeMessage message = new MimeMessage(s);

//設置郵件
InternetAddress fromAddr = null;
InternetAddress toAddr = null;

try
{
fromAddr = new InternetAddress(451144426+"@qq.com"); //郵件發送地址
message.setFrom(fromAddr); //設置發送地址

toAddr = new InternetAddress("[email protected]"); //郵件接收地址
message.setRecipient(Message.RecipientType.TO, toAddr); //設置接收地址

message.setSubject(title); //設置郵件標題
message.setText(content); //設置郵件正文
message.setSentDate(new Date()); //設置郵件日期

message.saveChanges(); //保存郵件更改信息

Transport transport = s.getTransport("smtp");
transport.connect("smtp.qq.com", "451144426", "密碼"); //伺服器地址，郵箱賬號，郵箱密碼
transport.sendMessage(message, message.getAllRecipients()); //發送郵件
transport.close();//關閉

}
catch (Exception e)
{
e.printStackTrace();
flag = false;//發送失敗
}

return flag;
}

這是一個javaMail的郵件發送代碼，需要一個mail.jar

❸ 如何使用Java發送qq郵件

方法:

1.前提准備工作：
首先，郵件的發送方要開啟POP3 和SMTP服務--即發送qq郵件的賬號要開啟POP3 和SMTP服務

2.開啟方法：
登陸qq郵箱
3.點擊 設置

4.點擊—-賬戶

5.找到：POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服務 —點擊開啟

6.送簡訊 —–點擊確定

7.稍等一會，很得到一個授權碼！ –注意：這個一定要記住，一會用到

8.點擊保存修改 —OK 完成

9.java 測試代碼：
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");// 連接協議
properties.put("mail.smtp.host", "smtp.qq.com");// 主機名
properties.put("mail.smtp.port", 465);// 埠號
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.ssl.enable", "true");//設置是否使用ssl安全連接 ---一般都使用
properties.put("mail.debug", "true");//設置是否顯示debug信息 true 會在控制台顯示相關信息
//得到回話對象
Session session = Session.getInstance(properties);
// 獲取郵件對象
Message message = new MimeMessage(session);
//設置發件人郵箱地址
message.setFrom(new InternetAddress("[email protected]"));
//設置收件人地址 message.setRecipients( RecipientType.TO, new InternetAddress[] { new InternetAddress("[email protected]") });
//設置郵件標題
message.setSubject("這是第一封Java郵件");
//設置郵件內容
message.setText("內容為： 這是第一封java發送來的郵件。");
//得到郵差對象
Transport transport = session.getTransport();
//連接自己的郵箱賬戶
transport.connect("[email protected]", "vvctybgbvvophjcj");//密碼為剛才得到的授權碼
//發送郵件 transport.sendMessage(message, message.getAllRecipients());
}
}
10.運行就會發出郵件了。。。。
下面是我收到郵件的截圖，當然我把源碼中的郵件地址都是修改了，不是真實的，你們測試的時候，可以修改能你們自己的郵箱。最後，祝你也能成功，如果有什麼問題，可以一起討論！

注意事項

得到的授權碼一定要保存好，程序中要使用

❹ 急java 發送郵件 急！~急！~ 高手快進來幫忙看看啊！~

這是我的連續發幾封郵件的代碼。連續發是為了163郵箱的積分，^_^。你可以參考下。
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"; // 需要你的郵箱帳號(僅@符號前面的)
public static final String password = "######"; // 需要你的郵箱密碼
private Properties props;

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

public SendEmail(){
props = new Properties();
InputStream is = null;
try {
/*當部署在web容器中時，路徑要修改
* Thread.currentThread().getContextClassLoader().getResource("").getPath();
* 得到的url是web容器中的項目下的class路徑
**/

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

}

/** email為接收郵箱，text為郵件正文
* @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", "歐陽");
Address addressTo = new InternetAddress(email, "xianlai");

message.setText(text);
message.setSubject("郵件標題");
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();//作為成員變數就只會創建一個SendEmail對象。

public void run() {
//在timer的run中就必須考慮好怎樣或者什麼時候退出的問題。
//這里是用count計數的方法來考慮退出的問題的。
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 怎樣用java實現郵件的發送

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();//用於加密後發送用戶名和密碼
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("已經建立連接!");
}

}

// 注冊到郵件伺服器
public void helo(String server, BufferedReader in, BufferedWriter out)
throws IOException {
int result;
result = getResult(in);
// 連接上郵件服務後,伺服器給出220應答
if (result != 220) {
throw new IOException("連接伺服器失敗");
}
result = sendServer("HELO " + server, in, out);
// HELO命令成功後返回250
if (result != 250) {
throw new IOException("注冊郵件伺服器失敗！");
}
}

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

public int getResult(BufferedReader in) {
String line = "";
try {
line = in.readLine();
/*
if (debug) {
System.out.println("伺服器返回狀態:" + line);
}
*/
} catch (Exception e) {
e.printStackTrace();
}
// 從伺服器返回消息中讀出狀態碼,將其轉換成整數返回

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("用戶驗證失敗！");
}

result=sendServer(encode.encode(message.getUser().getBytes()),in,out);
//System.out.println("用戶名： "+encode.encode(message.getUser().getBytes()));
if (result != 334) {
throw new IOException("用戶名錯誤！");
}
result=sendServer(encode.encode(message.getPassword().getBytes()),in,out);
//result=sendServer(message.getPassword(),in,out);
//System.out.println("密碼： "+encode.encode(message.getPassword().getBytes()));
if (result != 235) {
throw new IOException("驗證失敗！");
}
}

// 開始發送消息，郵件源地址
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("指定源地址錯誤");
}
}

// 設置郵件收件人
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("指定目的地址錯誤！");
}
}

// 郵件體
public void data(String from, String to, String subject, String content,
BufferedReader in, BufferedWriter out) throws IOException {
int result;
result = sendServer("DATA", in, out);
// 輸入DATA回車後,若收到354應答後,繼續輸入郵件內容
if (result != 354) {
throw new IOException("不能發送數據");
}
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();
// 句號加回車結束郵件內容輸入
result = sendServer(".", in, out);
//System.out.println(result);
if (result != 250) {
throw new IOException("發送數據錯誤");
}
}

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

// 發送郵件主程序
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;
}
}
再寫一個MailMessage.java，set/get方法即可。

❻ 用java寫收發郵件的程序，求助，在線

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("沒有郵件");
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("主體: " + 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("內容：\n" + m.getContent());
}
}

用JAVAMAIL很容易實現的。
