SPRING 邮件服务

[lovewgqwgq]

学习Spring 邮件服务的时候遇到了这个问题，该如何解决啊：
log4j:WARN No appenders could be found for logger (org.springframework.mail.javamail.JavaMailSenderImpl).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" org.springframework.mail.MailSendException; nested exception details (1) are:
Failed message 1:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
class javax.mail.SendFailedException: 504 5.5.2 <1c7ab2f16390497>: Helo command rejected: need fully-qualified hostname

at onlyfun.caterpillar.model.SimpleMailDemo.main(SimpleMailDemo.java:17)

代码如下：
package onlyfun.caterpillar.model;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;



public class SimpleMailDemo {
public static void main(String []args){
JavaMailSenderImpl senderImpl=new JavaMailSenderImpl();
senderImpl.setHost("mail.zjut.com");
SimpleMailMessage mailMessage=new SimpleMailMessage();
mailMessage.setTo("[e-mail]");
mailMessage.setFrom("[e-mail]");
mailMessage.setSubject("demo");
mailMessage.setText("content");
senderImpl.send(mailMessage);
System.out.println("OK.....");
}

}

这个错误是由于邮件服务商改了默认的smtp端口造成的。
发送邮件默认是25端口,但是有的部分邮件服务商用的不是25端口,而是465或587端口

if(this.smtp.indexOf("smtp.gmail.com")>=0)
{
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.smtp.socketFactory.fallback", "false");
properties.setProperty("mail.smtp.port", "465");
properties.setProperty("mail.smtp.socketFactory.port", "465");
}
