spring 发送MAIL

spring对mail的支持是org.springframework.mail.MailSender接口来定义的，其中的org.springframework.mail.javamail.JavamailSenderImpl这个实现类提供了对javamail的支持，下面简单介绍其用法，首先看下不用注入的方法，再看用注入的方法。

1、发送简单邮件的例子
     首先，我们要需要springframwork 1.2.8中lib目录下的j2ee目录的activation.jar和mail.jar文件，将它们放到工程的lib目录下去。
  发送一个简单邮件的例子如下
  import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.mail.SimpleMailMessage;

public class SimpleMailDemo {
    public static void main(String[] args) throws Exception {
        JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
        // 设定 Mail Server
        senderImpl.setHost("mail.xxxxx");
        
      //SMTP验证时，需要用户名和密码
        senderImpl.setUsername("abc");
        senderImpl.setPassword("defdf");
       
        // 建立邮件讯息
        SimpleMailMessage mailMessage = new SimpleMailMessage();
       
        // 设定收件人、寄件人、主题与内文
        mailMessage.setTo(hello@abc.com);
        mailMessage.setFrom(der@def.com);
        mailMessage.setSubject("Test");
        mailMessage.setText("This is a test!!!");
       
        // 传送邮件
        senderImpl.send(mailMessage);
       
        System.out.println("邮件传送OK..");
    }
}

2、发送HTML格式的邮件
    要发送HTML格式的话，要用org.springframework.mail.javamail.MimeMessageHelper来建立HTML邮件
  import org.springframework.mail.javamail.JavaMailSenderImpl;
import javax.mail.internet.MimeMessage;
import org.springframework.mail.javamail.MimeMessageHelper;
public class HTMLMailDemo {
    public static void main(String[] args) throws Exception {
        JavaMailSenderImpl senderImpl =
            new JavaMailSenderImpl();
        
      // 设定 Mail Server
        senderImpl.setHost("mail.xxxxx");
        
      //SMTP验证时，需要用户名和密码
        senderImpl.setUsername("abc");
        senderImpl.setPassword("defdf");
        
        // 建立邮件讯息
        MimeMessage mailMessage =
            senderImpl.createMimeMessage();
        MimeMessageHelper messageHelper =
            new MimeMessageHelper(mailMessage);
               
        // 设定收件人、寄件人、主题与内文
        messageHelper.setTo("xxx@your_mail_server.com");
        messageHelper.setFrom("xxx@your_mail_server.com");
        messageHelper.setSubject("Test");
        messageHelper.setText(
                "<html><head></head><body><h1>Hello! Spring!"
                + "</h1></body></html>", true);
       
        // 传送邮件
        senderImpl.send(mailMessage);
       
        System.out.println("邮件传送OK...");
    }
}
 
3、发送带附件的邮件
    这时要用MimeMessageHelper的addAttachement()方法
 import java.io.File;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import javax.mail.internet.MimeMessage;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.javamail.MimeMessageHelper;
public class AttachedFileDemo {
    public static void main(String[] args) throws Exception {
        JavaMailSenderImpl senderImpl =
                      new JavaMailSenderImpl();
        
                //SMTP验证时，需要用户名和密码
        senderImpl.setUsername("abc");
        senderImpl.setPassword("defdf");

                MimeMessage mailMessage =     senderImpl.createMimeMessage();
        MimeMessageHelper messageHelper =  new MimeMessageHelper(mailMessage, true);
                
           messageHelper.setTo("def@erer.net");
        messageHelper.setFrom("bfg@tom.com");
        messageHelper.setSubject("Test");
        messageHelper.setText(
            "<html><head></head><body><h1>Hello! Spring!"
            + "</h1></body></html>", true);
       
        FileSystemResource file =
                new FileSystemResource(
                           new File("d:/test.rar"));
        messageHelper.addAttachment("test.rar", file);
        
               senderImpl.send(mailMessage);
       
        System.out.println("OK");
    }
}


4、用注入的方式来配置邮件，和之前的差不多拉
  <?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.xxx.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();
    }
  }
}
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();
  }
  }
