javaMail的入门级问题

Question

没有认证，smtp服务器要求认证Session session;
Properties props = new Properties();
props.put("mail.smtp.auth","true");
PasswordAuthention auth = new passwordAuthention; //可以参考JavaMail的JavaDoc
......
session = Session.getInstance(props,auth);

Answer 1

给你一段程序
public void sendmail(){
                try{
                        Properties props=new Properties();
                        props.put("mail.smtp.auth","true");
                        props.put("mail.smtp.host",stmpname);                        Email_Autheticatorbean auth = new Email_Autheticatorbean(username,password);
                        Session mailConnection= Session.getInstance(props,auth);
                        Message msg = new MimeMessage(mailConnection);                        Address send = new InternetAddress(sendadd,sendname);
                        Address receive= new InternetAddress(receiveradd,receivername);                        msg.setContent(content,"text/plain");
                        msg.setFrom(send);
                        msg.setRecipient(Message.RecipientType.TO,receive);
                        msg.setSubject(subject);                        Transport.send(msg);
                        sendresult="邮件已经发送！";
                }
                catch (Exception e){
                        e.printStackTrace();
                        sendresult="邮件发送失败，请检查您的输入是否正确！";
}
  }其中Email_Autheticatorbean这样写package mailtest;import java.net.InetAddress;
import javax.mail.*;
import javax.mail.internet.*;
import java.awt.event.*;
import java.util.*;public class Email_Autheticatorbean  extends Authenticator
{
private String m_username = null;
private String m_userpass = null;public void setUsername(String username)
{
 m_username = username;
}public void setUserpass(String userpass)
{
 m_userpass = userpass;
}public Email_Autheticatorbean(String  user, String password)
{
   super();
   setUsername(user);
   setUserpass(password);}
public PasswordAuthentication getPasswordAuthentication()
{  return new PasswordAuthentication(m_username,m_userpass);
}
  public void setM_username(String m_username) {
    this.m_username = m_username;
  }
  public void setM_userpass(String m_userpass) {
    this.m_userpass = m_userpass;
  }
}
