按书上说的写了个邮件发送的小类,可老是发不出去,大家帮忙看看下.一起两个类,MailSedn.java是发送的,s.java是主类,代码如下:
//MailSend.java:
import java.io.*;
import java.text.*;
import java.net.*;
import java.util.Properties;
import java.util.Date;
import javax.mail.*;
import javax.mail.internet.*;
public class MailSend {
String subject = null,text = null,mailhost = null;
public MailSend(){
mailhost = "localhost ";
text = getUserText();
subject = "Welcome~ ";
}
public String sednMsg(String from,String to){
boolean debug = false;
String err = null;
try{
Properties props = System.getProperties();
if(mailhost!=null)
props.put( "mail.smtp.host ", mailhost);
Session session = Session.getDefaultInstance(props,null);
if(debug)
session.setDebug(true);
Message msg = new MimeMessage(session);
//from = null;
if(from != null){
msg.setFrom(new InternetAddress(from));
System.out.print( "from is not null~ ");
}
else{
msg.setFrom();
System.out.print( "from is null~ ");
}
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to,false));
msg.setSubject(subject);
msg.setText(text);
msg.setSentDate(new Date());
Transport.send(msg);
System.out.println( "Mail has been send successfully! ");
}
catch (Exception e){
e.printStackTrace();
err = e.toString();
err = "Mail send has an error! ";
}
return err;
}
public String getUserText(){
String userText = " ";
String nowDate = DateFormat.getDateInstance().format(new Date());
userText = "hello~ ";
return userText;
}
}
//S.java
public class S {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String mail = new String( "suhuajun2001@163.com ");
MailSend ms = new MailSend();
ms.sednMsg( "shj0717@gmail.com ", "suhuajun2001@163.com ");
//ms.sednMsg( " ", mail);
}
}
错误提示如下:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
