java郵件

㈠ java發郵件的幾種方式

下面給你介紹3種發送郵件的方式：

1：使用JavaMail發送郵件

㈡ Java發送郵件

本地要 有smtp伺服器，才可以測試 。。。。。。。。。。。。。~

~~~~~~~~~~~~~~~~~~~~~~~~

㈢ javamail如何判斷郵件狀態

pop3伺服器是不支持此做法的,
你用Foxmail收郵件(保留備份在伺服器上),然後再用郵件伺服器自帶的web收郵件,最後用OE收郵件,
我以前處理這一問題的做法供你參考參考:
收郵件時把郵件的唯一的UID字元串取出,並保存到web伺服器的一個文本文件中,
這樣就可以實現通過判斷pop3伺服器上的每一郵件的UID
是否已存在於文本文件中來確定是否為新郵件了.

㈣ java 代碼發郵件怎麼添加附件

實現java發送郵件的過程大體有以下幾步：

准備一個properties文件，該文件中存放SMTP伺服器地址等參數。

利用properties創建一個Session對象

利用Session創建Message對象，然後設置郵件主題和正文

利用Transport對象發送郵件

需要的jar有2個：activation.jar和mail.jar發送附件，需要用到Multipart對象。

importjava.io.File;
importjava.io.IOException;
importjava.io.InputStream;
importjava.util.Properties;

importjavax.activation.DataHandler;
importjavax.activation.DataSource;
importjavax.activation.FileDataSource;

importjavax.mail.internet.MimeMultipart;
importjavax.mail.internet.MimeUtility;

{
privateMimeMessagemessage;
privateSessionsession;
privateTransporttransport;

privateStringmailHost="";
privateStringsender_username="";
privateStringsender_password="";

privatePropertiesproperties=newProperties();

/*
*初始化方法
*/
publicJavaMailWithAttachment(booleandebug){
InputStreamin=JavaMailWithAttachment.class.getResourceAsStream("MailServer.properties");
try{
properties.load(in);
this.mailHost=properties.getProperty("mail.smtp.host");
this.sender_username=properties.getProperty("mail.sender.username");
this.sender_password=properties.getProperty("mail.sender.password");
}catch(IOExceptione){
e.printStackTrace();
}

session=Session.getInstance(properties);
session.setDebug(debug);//開啟後有調試信息
message=newMimeMessage(session);
}

/**

*
*@paramsubject
*郵件主題
*@paramsendHtml
*郵件內容
*@paramreceiveUser
*收件人地址
*@paramattachment
*附件
*/
publicvoiddoSendHtmlEmail(Stringsubject,StringsendHtml,StringreceiveUser,Fileattachment){
try{
//發件人
InternetAddressfrom=newInternetAddress(sender_username);
message.setFrom(from);

//收件人
InternetAddressto=newInternetAddress(receiveUser);
message.setRecipient(Message.RecipientType.TO,to);

//郵件主題
message.setSubject(subject);

//向multipart對象中添加郵件的各個部分內容，包括文本內容和附件
Multipartmultipart=newMimeMultipart();

//添加郵件正文
BodyPartcontentPart=newMimeBodyPart();
contentPart.setContent(sendHtml,"text/html;charset=UTF-8");
multipart.addBodyPart(contentPart);

//添加附件的內容
if(attachment!=null){
BodyPartattachmentBodyPart=newMimeBodyPart();
DataSourcesource=newFileDataSource(attachment);
attachmentBodyPart.setDataHandler(newDataHandler(source));

//網上流傳的解決文件名亂碼的方法，其實用MimeUtility.encodeWord就可以很方便的搞定
//這里很重要，通過下面的Base64編碼的轉換可以保證你的中文附件標題名在發送時不會變成亂碼
//sun.misc.BASE64Encoderenc=newsun.misc.BASE64Encoder();
//messageBodyPart.setFileName("=?GBK?B?"+enc.encode(attachment.getName().getBytes())+"?=");

//MimeUtility.encodeWord可以避免文件名亂碼
attachmentBodyPart.setFileName(MimeUtility.encodeWord(attachment.getName()));
multipart.addBodyPart(attachmentBodyPart);
}

//將multipart對象放到message中
message.setContent(multipart);
//保存郵件
message.saveChanges();

transport=session.getTransport("smtp");
//smtp驗證，就是你用來發郵件的郵箱用戶名密碼
transport.connect(mailHost,sender_username,sender_password);
//發送
transport.sendMessage(message,message.getAllRecipients());

System.out.println("sendsuccess!");
}catch(Exceptione){
e.printStackTrace();
}finally{
if(transport!=null){
try{
transport.close();
}catch(MessagingExceptione){
e.printStackTrace();
}
}
}
}

publicstaticvoidmain(String[]args){
JavaMailWithAttachmentse=newJavaMailWithAttachment(true);
Fileaffix=newFile("c:\測試-test.txt");
se.doSendHtmlEmail("郵件主題","郵件內容","[email protected]",affix);//

}

㈤ 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。

㈧ java 發送郵件

要兩個java文件 還有一個mail.jar是不是只能用javamail誰也不敢說

第一個：

public class Constant {

public static final String mailAddress ="用戶名@163.com";
public static final String mailCount ="用戶名";
public static final String mailPassword ="密碼";
public static final String mailServer ="smtp.163.com";
//pukeyouxintest,

}

第二個：

import java.util.Date;
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;

public class SendMail {
/**
* 發送簡單郵件
* @param str_from：發件人地址
* @param str_to:收件人地址
* @param str_title：郵件標題
* @param str_content：郵件正文
*/
public static void send(String str_from,String str_to,String str_title,String str_content) {

// str_content="<a href='www.163.com'>html元素</a>"; //for testing send html mail!

try {
//建立郵件會話
Properties props=new Properties(); //用來在一個文件中存儲鍵-值對的，其中鍵和值是用等號分隔的，
//存儲發送郵件伺服器的信息
props.put("mail.smtp.host",Constant.mailServer);
//同時通過驗證
props.put("mail.smtp.auth","true");
//根據屬性新建一個郵件會話
Session s=Session.getInstance(props);
s.setDebug(true); //有他會列印一些調試信息。

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

//設置郵件
InternetAddress from= new InternetAddress(str_from); //[email protected]
message.setFrom(from); //設置發件人的地址
//
// //設置收件人,並設置其接收類型為TO
InternetAddress to=new InternetAddress(str_to); //[email protected]
message.setRecipient(Message.RecipientType.TO, to);

//設置標題
message.setSubject(str_title); //java學習

//設置信件內容
// message.setText(str_content); //發送文本郵件 //你好嗎？
message.setContent(str_content, "text/html;charset=gbk"); //發送HTML郵件 //<b>你好</b><br><p>大家好</p>
//設置發信時間
message.setSentDate(new Date());

//存儲郵件信息
message.saveChanges();

//發送郵件
Transport transport=s.getTransport("smtp");
//以smtp方式登錄郵箱,第一個參數是發送郵件用的郵件伺服器SMTP地址,第二個參數為用戶名,第三個參數為密碼
transport.connect(Constant.mailServer,Constant.mailCount,Constant.mailPassword);
//發送郵件,其中第二個參數是所有已設好的收件人地址
transport.sendMessage(message,message.getAllRecipients());
transport.close();

} catch (Exception e) {
e.printStackTrace();
}
}

public static void main(String[] args) {
//測試用的，你吧你想寫的內容寫上去就行
send(Constant.mailAddress,"收件人郵箱","標題","<b>內容</b>");
}
}

然後把mail.jar導入，就可以了，我用的是163 的，其他的吧相應的伺服器改一下就行了

注意點：1 jar可能有沖突，如果是demo可以直接應用mail.jar

如果是一個工程則要替換javaEE中的mail.jar包

2 關於properties配置文件的地址問題

Class.getResourceAsStream(String path) ： path 不以』/'開頭時默認是從此類所在的包下取資源，以』/'開頭則是從

ClassPath根下獲取。其只是通過path構造一個絕對路徑，最終還是由ClassLoader獲取資源。

㈩ 怎麼用JAVA實現郵件發送

用java mail 庫
