用Spring来发邮件-转载

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)
   */
}

呵呵, 现在就可以发送Email了.
