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("aaaa@qq.com");// 接受者
            mail.setFrom("bbbb@163.com");// 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("aaaa@qq.com")。mail.setTo("cccc@qq.com")....

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；
