使用spring发送邮件例

使用spring发送邮件例

     做了个spring发送纯文本文件以及发送带附件的邮件的例子，共享之。
      1. SpringMail类
     

import  org.springframework.context.ApplicationContext;
import  org.springframework.context.support.FileSystemXmlApplicationContext;
import  org.springframework.mail.SimpleMailMessage;
import  org.springframework.mail.javamail.JavaMailSender;
import  org.springframework.mail.javamail.MimeMessagePreparator;

import  javax.mail.internet.MimeMessage;
import  javax.mail.MessagingException;
import  javax.mail.Message;
import  javax.mail.internet.InternetAddress;
import  javax.activation.FileDataSource;
import  javax.activation.DataHandler;
import  javax.mail.internet.MimeMultipart;
import  javax.mail.internet.MimeBodyPart;
import  javax.mail.Multipart;

import  java.util.List;
import  java.util.ArrayList;
import  java.util.Date;
import  java.util.Iterator;

public   class  SpringMail  {

    public static void main(String[] args) throws Exception {
        ApplicationContext ctx = new FileSystemXmlApplicationContext(
                "src/applicationContext.xml");
        JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
        SpringMail springMail = new SpringMail();
        
        //测试发送只有文本信息的简单测试
        springMail.sendTextMail(sender);
        
        //测试发送带附件的邮件
        springMail.sendMimeMessage(sender);
    }
    
    /** *//**

    }
    
    /** *//**

     * @throws Exception
     */
    private void sendMimeMessage(final JavaMailSender sender) throws Exception {
        //附件文件集合
        final List files = new ArrayList();
        MimeMessagePreparator mimeMail = new MimeMessagePreparator() {
            public void prepare(MimeMessage mimeMessage) throws MessagingException {
                mimeMessage.setRecipient(Message.RecipientType.TO, 
                        new InternetAddress("[email protected]"));
                mimeMessage.setFrom(new InternetAddress("[email protected]"));
                mimeMessage.setSubject("Spring发送带附件的邮件", "gb2312"); 
                
                Multipart mp = new MimeMultipart();
                
                //向Multipart添加正文
                MimeBodyPart content = new MimeBodyPart();
                content.setText("内含spring邮件发送的例子，请查收!");
                
                //向MimeMessage添加（Multipart代表正文）
                mp.addBodyPart(content);
                files.add("src/SpringMail.java");
                files.add("src/applicationContext.xml");
                
                //向Multipart添加附件
                Iterator it = files.iterator();
                while(it.hasNext()) {
                    MimeBodyPart attachFile = new MimeBodyPart();
                    String filename = it.next().toString();
                    FileDataSource fds = new FileDataSource(filename);
                    attachFile.setDataHandler(new DataHandler(fds));
                    attachFile.setFileName(fds.getName());
                    mp.addBodyPart(attachFile);
                }
                
                files.clear();
                
                //向Multipart添加MimeMessage
                mimeMessage.setContent(mp);
                mimeMessage.setSentDate(new Date());
            }
        };

        //发送带附件的邮件
        sender.send(mimeMail);
        
        System.out.println("成功发送带附件邮件!");
    }
}

      2. spring的配置文件
     

<? xml version="1.0" encoding="UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >

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

         </ property >
         < property  name ="javaMailProperties" >
             < props >
                 < prop  key ="mail.smtp.auth" > true </ prop >

             < value > <!--  此处填写密码  --> </ value >
         </ property >
     </ bean >
</ beans >

    刚才发现一bug，当附件名为中文时，会出现中文乱码问题，对sendMimeMessage方法进行了部分修改，如下：
   

               sun.misc.BASE64Encoder enc  =   new  sun.misc.BASE64Encoder();
                files.add( " src/SpringMail.java " );
                files.add( " src/applicationContext.xml " );
                files.add( " src/谢星星.xml " );
                
                 // 向Multipart添加附件
                Iterator it  =  files.iterator();
              while (it.hasNext())  {
                    MimeBodyPart attachFile = new MimeBodyPart();
                    String filename = it.next().toString();
                    FileDataSource fds = new FileDataSource(filename);
                    attachFile.setDataHandler(new DataHandler(fds));
                    attachFile.setFileName("=?GBK?B?"+enc.encode(fds.getName().getBytes())+"?=");
                    mp.addBodyPart(attachFile);
                }
