⑴ 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
⑵ 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
⑶ 如何用java實現發送html格式的郵件
首先Java發送郵件需要用到JavaMail，先到Oracle官網上下載好最新版本的JavaMail（剛才看了一下，最新是1.5.3），把下載的這個jar文件放到classpath里（如果是Web項目，就放到WEB-INF/lib目錄下。
JavaMail主要支持發送純文本的和html格式的郵件。
發送html格式的郵件的一個常式如下：
importjavax.mail.internet.InternetAddress;
importjavax.mail.internet.MimeMessage;
importjavax.mail.internet.MimeUtility;
importjavax.mail.Session;
importjavax.mail.MessagingException;
importjavax.mail.Transport;
publicclassSendHtmlMail{
publicstaticvoidsendMessage(StringsmtpHost,
Stringfrom,Stringto,
Stringsubject,StringmessageText)
throwsMessagingException,java.io.UnsupportedEncodingException{
//Step1:Configurethemailsession
System.out.println("Configuringmailsessionfor:"+smtpHost);
java.util.Propertiesprops=newjava.util.Properties();
props.setProperty("mail.smtp.auth","true");//指定是否需要SMTP驗證
props.setProperty("mail.smtp.host",smtpHost);//指定SMTP伺服器
props.put("mail.transport.protocol","smtp");
SessionmailSession=Session.getDefaultInstance(props);
mailSession.setDebug(true);//是否在控制台顯示debug信息
//Step2:Constructthemessage
System.out.println("Constructingmessage-from="+from+"to="+to);
InternetAddressfromAddress=newInternetAddress(from);
InternetAddresstoAddress=newInternetAddress(to);
MimeMessagetestMessage=newMimeMessage(mailSession);
testMessage.setFrom(fromAddress);
testMessage.addRecipient(javax.mail.Message.RecipientType.TO,toAddress);
testMessage.setSentDate(newjava.util.Date());
testMessage.setSubject(MimeUtility.encodeText(subject,"gb2312","B"));
testMessage.setContent(messageText,"text/html;charset=gb2312");
System.out.println("Messageconstructed");
//Step3:Nowsendthemessage
Transporttransport=mailSession.getTransport("smtp");
transport.connect(smtpHost,"webmaster","password");
transport.sendMessage(testMessage,testMessage.getAllRecipients());
transport.close();
System.out.println("Messagesent!");
}
publicstaticvoidmain(String[]args){
StringsmtpHost="localhost";
Stringfrom="[email protected]";
Stringto="[email protected]";
Stringsubject="html郵件測試";//subjectjavamail自動轉碼
StringBuffertheMessage=newStringBuffer();
theMessage.append("<h2><fontcolor=red>這倒霉孩子</font></h2>");
theMessage.append("<hr>");
theMessage.append("<i>年年失望年年望</i>");
try{
SendHtmlMail.sendMessage(smtpHost,from,to,subject,theMessage.toString());
}
catch(javax.mail.MessagingExceptionexc){
exc.printStackTrace();
}
catch(java.io.){
exc.printStackTrace();
}
}
}
JavaMail是封裝了很多郵件操作的，所以使用起來不很困難，建議你到JavaMail官網看一下API或下載Java Doc API文檔。
⑷ 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");
}
}
}
⑸ java如何實現復制excel中內容並粘貼到郵件發
主要是用到java裡面的i/o流。代碼例子如下：
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
/**
* java讀寫文件,復制文件
* 讀取d:/1.txt文件內容,寫入f:/text.txt文件中.
* @author young
*
*/
public class FileWriterTest {
// 讀寫文件
public static void rwFile(){
FileWriter fw = null;
BufferedReader br = null;
try {
fw = new FileWriter("f:\\text.txt", true);
br = new BufferedReader(new InputStreamReader(
new FileInputStream("d:\\1.txt"), "UTF-8"));
String line = null;
while ((line = br.readLine()) != null) {
System.out.println("文件內容: " + line);
fw.write(line);
fw.flush();
}
br.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fw != null) {
try {
fw.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
public static void main(String[] args) {
rwFile();
}
}
首先在D盤新建文件1.txt，輸入任意內容。然後執行java代碼即可。
⑹ 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。
