Java的Spring框架中实现发送邮件功能的核心代码示例

这篇文章主要介绍了Java的Spring框架中实现发送邮件功能的核心代码示例,包括发送带附件的邮件功能的实现,需要的朋友可以参考下

Spring中已经封装了邮件操作类，通过spring配置文件可以便捷地注入到controller、action等地方。

下面是配置：

       

mail配置

Email Configuration： mail.host=smtp.163.com mail.port=25 mail.user=[e-mail] mail.passwd=xxxxxxxx mail.from=[e-mail]

控制器中注入mailSender：

@Controller public class EmailController { private MailSender mailSender; @Value("${mail.from}") String emailFrom; @Autowired public void setMailSender(MailSender mailSender) { this.mailSender = mailSender; } @RequestMapping(value="/sendEmail",method=RequestMethod.POST) public ModelAndView sendEmail(@modelattribute("newEmail") ContactEmail newEmail, BindingResult bindResult,SessionStatus status){ SimpleMailMessage message = new SimpleMailMessage(); message.setTo(newEmail.getTo()); message.setFrom(emailFrom); message.setSubject(newEmail.getSubject()); message.setText(newEmail.getContent()); String result = ""; try{ mailSender.send(message); result = "Email was sent!"; }catch(MailException e){ result = "Sending email Failed!

"+e.getMessage(); } ModelAndView view = new ModelAndView("emailResult"); view.addobject("result", result); return view; } }

mail form：

subject:

content:

发送带附件的邮件：

try{ JavaMailSenderImpl senderImpl = new JavaMailSenderImpl(); Properties props = new Properties(); props.put("mail.smtp.auth", "true"); senderImpl.setHost("smtp.163.com"); senderImpl.setUsername("zhangfl85"); senderImpl.setPassword("851010"); senderImpl.setJavaMailProperties(props); MimeMessage mimeMessge = senderImpl.createMimeMessage(); MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessge,true); mimeMessageHelper.setTo("[e-mail]"); mimeMessageHelper.setFrom("[e-mail]"); mimeMessageHelper.setSubject("添加附件测试"); mimeMessageHelper.setText("test",true); FileSystemResource img = new FileSystemResource(new File("I:/liang.jpg")); mimeMessageHelper.addAttachment(MimeUtility.encodeWord("3M样品仓库标准送货单模板.jpg"), ,img); senderImpl.send(mimeMessge); }catch(Exception e){ e.printstacktrace(); }
