java發郵件
❶ 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。

}
}
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。
❸ 怎麼用JAVA實現郵件發送
用java mail 庫
❹ 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
❺ 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
❻ 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
❼ 使用javaMailSender發送郵件
郵件
❽ 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。

❿ 怎樣用java發送郵件
首先下載 JavaMail jar 包,並導入到項目中。下載地址
編寫代碼,代碼如下:
importjavax.mail.Authenticator;
importjavax.mail.Message;
importjavax.mail.MessagingException;
importjavax.mail.PasswordAuthentication;
importjavax.mail.Session;
importjavax.mail.Transport;
importjavax.mail.internet.AddressException;
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;
publicclassApp45{
publicstaticvoidmain(String[]args)throwsAddressException,MessagingException{
Propertiesproperties=System.getProperties();
properties.setProperty("mail.smtp.host","郵件發送伺服器");
properties.setProperty("mail.smtp.auth","true");
Sessionsession=Session.getDefaultInstance(properties,newAuthenticator(){
@Override
(){
//設置發件人郵件帳號和密碼
("郵件帳號","密碼");
}
});
MimeMessagemessage=newMimeMessage(session);
//設置發件人郵件地址
message.setFrom(newInternetAddress("發件人郵件地址"));
//設置收件人郵件地址
message.addRecipient(Message.RecipientType.TO,newInternetAddress("收件人郵件地址"));
message.setSubject("這里是郵件主題。");
message.setText("這里是郵件內容。");
Transport.send(message);
}
}
