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)

return flag;
}

}
『伍』 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
『陸』 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

import org.apache.commons.mail.EmailException; import org.apache.commons.mail.HtmlEmail; public class Mail { public static void main(String[] args) { //SimpleEmail email = new SimpleEmail(); HtmlEmail email = new HtmlEmail(); email.setHostName("smtp.163.com");//郵件伺服器 email.setAuthentication("xingui5624", "******");//smtp認證的用戶名和密碼 try { email.addTo("[email protected]");//收信者 email.setFrom("[email protected]", "******");//發信者 email.setSubject("xingui5624的測試郵件");//標題 email.setCharset("UTF-8");//編碼格式 email.setMsg("這是一封xingui5624的測試郵件");//內容 email.send();//發送 System.out.println("send ok.........."); } catch (EmailException e) { e.printStackTrace(); } } } 【如果發送不成功，可能是你的jar包問題，javamail 的jar可能和jdk1.5以上的j2ee的jar沖突。還有就是可能你的郵箱不支持pop3和smtp協議。】

『玖』 java中如何實現公司郵箱發送郵件配置
Java中可以通過Javamail API實現公司郵箱郵件發送配置，Java mail是利用現有的郵箱賬戶發送郵件的版工具，具體步權驟如如下：
1、通過JavamailAPI設置發送者郵箱用戶名及密碼
