java邮件发送

㈠ java Mail发送邮件

连接的错误，smtp是需要登录服务器的使用的是base64的编码格式。没有代码也不太清楚 你哪里错了

㈡ 使用javaMailSender发送邮件

邮件

㈢ 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。

㈣ 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

㈤ Java发送邮件

本地要 有smtp服务器，才可以测试 。。。。。。。。。。。。。~

㈥ java 代码发邮件怎么添加附件

实现java发送邮件的过程大体有以下几步：

准备一个properties文件，该文件中存放SMTP服务器地址等参数。

利用properties创建一个Session对象

利用Session创建Message对象，然后设置邮件主题和正文

利用Transport对象发送邮件

需要的jar有2个：activation.jar和mail.jar发送附件，需要用到Multipart对象。

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

importjavax.activation.DataHandler;

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);//开启后有调试信息
message=newMimeMessage(session);
}

//发送
transport.sendMessage(message,message.getAllRecipients());

System.out.println("sendsuccess!");
}catch(Exceptione){
e.printStackTrace();

注意点：1 jar可能有冲突，如果是demo可以直接应用mail.jar

如果是一个工程则要替换javaEE中的mail.jar包

2 关于properties配置文件的地址问题

Class.getResourceAsStream(String path) ： path 不以’/'开头时默认是从此类所在的包下取资源，以’/'开头则是从

ClassPath根下获取。其只是通过path构造一个绝对路径，最终还是由ClassLoader获取资源。

㈧ 如何用java实现发送html格式的邮件

首先Java发送邮件需要用到JavaMail，先到Oracle官网上下载好最新版本的JavaMail（刚才看了一下，最新是1.5.3），把下载的这个jar文件放到classpath里（如果是Web项目，就放到WEB-INF/lib目录下。

JavaMail主要支持发送纯文本的和html格式的邮件。

发送html格式的邮件的一个例程如下：

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验证
props.setProperty("mail.smtp.host",smtpHost);//指定SMTP服务器
props.put("mail.transport.protocol","smtp");
SessionmailSession=Session.getDefaultInstance(props);
mailSession.setDebug(true);//是否在控制台显示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邮件测试";//subjectjavamail自动转码

StringBuffertheMessage=newStringBuffer();
theMessage.append("<h2><fontcolor=red>这倒霉孩子</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是封装了很多邮件操作的，所以使用起来不很困难，建议你到JavaMail官网看一下API或下载Java Doc API文档。

㈨ 怎么用JAVA实现邮件发送

用java mail 库

㈩ 怎样用java发送邮件

1. 首先下载 JavaMail jar 包，并导入到项目中。下载地址

2. 编写代码，代码如下：

3. 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","邮件发送服务器");
   		
   		properties.setProperty("mail.smtp.auth","true");
   		
   		Sessionsession=Session.getDefaultInstance(properties,newAuthenticator(){
   			@Override
   			(){
   				
   				//设置发件人邮件帐号和密码
   				("邮件帐号","密码");
   			}
   		});
   		
   		MimeMessagemessage=newMimeMessage(session);
   		
   		//设置发件人邮件地址
   		message.setFrom(newInternetAddress("发件人邮件地址"));
   		
   		//设置收件人邮件地址
   		message.addRecipient(Message.RecipientType.TO,newInternetAddress("收件人邮件地址"));
   		
   		message.setSubject("这里是邮件主题。");
   		
   		message.setText("这里是邮件内容。");
   		
   		Transport.send(message);
   	}
   }
