用spring框架技术发邮件

用spring框架技术发邮件

这次来看看Spring提高的一些有用过的JEE中使用到的功能,如发送Email, 执行定时任务...

先来看看发送Email吧, 在Spring中发送Email是很简单的,使用Spring提高的MailSender和MailMessage就可以了,配置代码如下:

<? xml version = "1.0" encoding = "UTF-8" ?>

<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "spring-beans.dtd" >

< beans >

< bean id = "mailSender" class = "org.springframework.mail.javamail.JavaMailSenderImpl" >

< property name = "host" >

  < value > smtp.163.com </ value >

</ property >

< property name = "javaMailProperties" >

  < props >

    <!-- 如果要使用用户名和密码验证,这一步需要 -->

    < prop key = "mail.smtp.auth" > true </ prop >

  </ props >

</ property >

< property name = "username" >

< value > 你的Email地址 </ value >

</ property >

< property name = "password" >

< value > 你的Email密码 </ value >

</ property >

</ bean >

<!-- 简单的message -->

< bean id = "mailMessage" class = "org.springframework.mail.SimpleMailMessage" >

< property name = "to" >

< value > 收件人地址 </ value >

</ property >

< property name = "from" >

< value > 你的地址 </ value >

</ property >

< property name = "subject" > <!-- Email 标题 -->

< value > A Spring Mail sender </ value >

</ property >

</ bean >

<!-- 测试发送的类 -->

< bean id = "testMailSender" class = "test.mail.TestSenderMail" >

< property name = "mailMessage" >

< ref bean = "mailMessage" />

</ property >

< property name = "mailSender" >

< ref bean = "mailSender" />

</ property >

</ bean >

</ beans >

上面的配置好以后就可以直接发送了, 看看TestSenderMail.java的代码:

package test.mail;

import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

public class TestSenderMail {
  private MailSender mailSender;
  private SimpleMailMessage mailMessage;
  
  public TestSenderMail() {
    
  }
  
  public SimpleMailMessage getMailMessage() {
    return mailMessage;
  }
  public void setMailMessage(SimpleMailMessage mailMessage) {
    this.mailMessage = mailMessage;
  }
  public MailSender getMailSender() {
    return mailSender;
  }
  public void setMailSender(MailSender mailSender) {
    this.mailSender = mailSender;
  }
  
  public void sendMail() {
    SimpleMailMessage message = new SimpleMailMessage(mailMessage);
    //设置email内容,
    message.setText("测试Spring 发送Email.");
    
    try {
      mailSender.send(message);
    } catch (MailException e) {
      // TODO Auto-generated catch block
      System.out.println("O . 发送Email失败了....");
      e.printStackTrace();
    }
  }
}

很简单吧. 下面是测试类: TestApp.java

package test.mail;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestApp {

  /**
   * @param args
   */
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    ApplicationContext context = new ClassPathXmlApplicationContext(
        "test/mail/mail.xml");

    TestSenderMail sender = (TestSenderMail) context
        .getBean("testMailSender");
    sender.sendMail();
  }
  //抛出如下异常,是瑞星监控的问题,关闭就可以了
  /**
   * DEBUG SMTP: QUIT failed with 250 O . 发送Email失败了....
   * org.springframework.mail.MailSendException: Could not send mails: 354
   * 
   * com.sun.mail.smtp.SMTPSendFailedException: 354
   * 
   * at
   * com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
   * at com.sun.mail.smtp.SMTPTransport.finishData(SMTPTransport.java:1215) at
   * com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:586)
   */
}
