編輯MailInfo

編輯MessageSender

編輯MailAuthenticator
package util;

/**

寫一個MailDemo進行測試
package test;
import java.util.ArrayList;
import java.util.List;
import util.MailInfo;
import util.MessageSender;
public class MailDemo {
public static void main(String[] args) {
mail();
}
public static void mail(){
String serverHost="smtp.qq.com";
String user="[email protected]"; //使用者名稱
String password="chcvuocdaffbbhfh"; //密碼
String fromAddress=user; //郵件地址
String title="郵件測試Demo";
String content="郵件測試成功";
String fileName="E:\\a.txt";
List<String> receiver=new ArrayList<String>();
receiver.add("[email protected]");
List<String> ccReceiver=new ArrayList<String>();
//新增抄送人
ccReceiver.add("[email protected]");
ccReceiver.add("[email protected]");
MailInfo mailInfo = new MailInfo(serverHost,user,password,fromAddress,title,content,receiver,ccReceiver, fileName);
MessageSender.sendMail(mailInfo);
}
}
