使用Spring JavaMail发送邮件总结

阅读更多

一直以来都是用javax.mail来写email发送，看了spring的javamail之后才知道javax.mail臃肿繁杂。

下面总结一下spring javamail的应用：


首先导入使用jar包：activation.jar，commons-logging-1.0.4.jar，mail.jar，spring.jar

 

1、使用xml配置javamail：
在classpath底下新建application-mail.xml，内容如下：

    
    
        
            stmp.163.com
        
        
            
                true
                25000
            
        
        
            [email protected]
        
        
            xxxxxx
        
    

  或者把以上的Beans配置到applicaiont.xml里面也可以。

 

2、发送Email类：

public class SendMail {
 public ApplicationContext ctx = null;
 public SendMail() {
  //获取上下文
  ctx = new ClassPathXmlApplicationContext("applicationContext-mail.xml");
 }
 public void send() {
  //获取JavaMailSender bean
  JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
  SimpleMailMessage mail = new SimpleMailMessage(); //注意SimpleMailMessage只能用来发送text格式的邮件


  try {
   mail.setTo("[email protected]");//接受者
   mail.setFrom("[email protected]");//发送者,这里还可以另起Email别名，不用和xml里的username一致
   mail.setSubject("spring mail test!");//主题
   mail.setText("springMail的简单发送测试");//邮件内容
   sender.send(mail);
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 

 发送html格式的Email：

 

public class SendMail {
 public ApplicationContext ctx = null;
 public SendMail() {
  //获取上下文
  ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
 }
 public void send() {
  //获取JavaMailSender bean
  JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
  JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
  MimeMessage mailMessage = senderImpl.createMimeMessage();
  //设置utf-8或GBK编码，否则邮件会有乱码
  MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,true,"utf-8");
  try {
   messageHelper.setTo(email.getEmail());//接受者   
   messageHelper.setFrom("[email protected]");//发送者
   messageHelper.setSubject("测试邮件");//主题
   //邮件内容，注意加参数true，表示启用html格式
   messageHelper.setText("
hello!!chao.wang
",true);
   sender.send(mailMessage);
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

 

发送html格式并带有附件的Email：

public class SendMail {
 public ApplicationContext ctx = null;
 public SendMail() {
  //获取上下文
  ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
 }
 public void send() {
  //获取JavaMailSender bean
  JavaMailSender sender = (JavaMailSender) ctx.getBean("mailSender");
  JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
  MimeMessage mailMessage = senderImpl.createMimeMessage();
  //设置utf-8或GBK编码，否则邮件会有乱码
  MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,true,"utf-8");
  try {
   messageHelper.setTo(email.getEmail());//接受者   
   messageHelper.setFrom("[email protected]");//发送者
   messageHelper.setSubject("测试邮件");//主题
   //邮件内容，注意加参数true
   messageHelper.setText("
hello!!chao.wang
",true);
   //附件内容
   messageHelper.addInline("a", new File("E:/xiezi.jpg"));
   messageHelper.addInline("b", new File("E:/logo.png")); 
   File file=new File("E:/测试中文文件.rar");  
   // 这里的方法调用和插入图片是不同的，使用MimeUtility.encodeWord()来解决附件名称的中文问题
   messageHelper.addAttachment(MimeUtility.encodeWord(file.getName()), file); 
   sender.send(mailMessage);
  } catch (Exception e) {
   e.printStackTrace();
  }
 }
