Spring发送邮件_javax.mail.AuthenticationFailedException异常已解决

在Spring项目中须要增加监控功能。监控过程中发现异常时。须要邮件报警。最初选择用javamail发送，代码量比較大（相对于spring发送）。终于选择Spring邮件发送~

以下贴一下实现的代码以及注意事项；

代码结构非常easy一个java类和一个xml文件，用到三个jar包，demo下载地址http://download.csdn.net/detail/jeofey/8892859

这里仅仅是简单的发送，假设须要发送附件或者HTML格式的邮件的话，代码在文章末尾

 package mail;
 import javax.mail.MessagingException;

 import org.springframework.context.ApplicationContext;
 import org.springframework.context.support.FileSystemXmlApplicationContext;
 import org.springframework.mail.SimpleMailMessage;
 import org.springframework.mail.javamail.JavaMailSender;
 /**
  *  @author Owner
  *  springMail发送邮件
  *  SendMail.java
  */
 public class SendMail {
     public ApplicationContext ctx = null;
     public SendMail() {
         ctx = new FileSystemXmlApplicationContext("src/mail/applicationContext-mail.xml");
     }
     /**
      * 主測试方法
      *
      * @throws MessagingException
      */
     public static void main(String[] args) {
         new SendMail().sendMail();
     }
     /**
      * 发送简单邮件
      */
     public void sendMail() {
         JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");// 获取JavaMailSender
         SimpleMailMessage mail = new SimpleMailMessage();
         try {
             mail.setTo("[email protected]");// 接受者
             mail.setFrom("[email protected]");// 发送者
             mail.setSubject("s邮件主题");// 主题
             mail.setText("springMail 的简单发送測试");// 邮件内容
             sender.send(mail);
             System.out.println("发送完成");
         } catch (Exception e) {
             e.printStackTrace();
         }
     }

 }

注意事项：在读取xml配置文件时，用的是FileSystemXmlApplicationContext实现类，在书写路径的时候不能仅仅写文件名称，虽然java文件和xml文件是在同一文件夹下。

假设收件人有多个时，mail.setTo("[email protected]")。mail.setTo("[email protected]")....

注意问题：username须要书写正确，必须是发送邮件中设定好的username，假设没设置。默认是邮件地址。当初这里没写正确，验证时出现了异常；
