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：

p:host="${mail.host}" p:port="${mail.port}"

p:username="${mail.user}" p:password="${mail.passwd}">

mail配置

Email Configuration：

mail.host=smtp.163.com

mail.port=25

mail.user=xxxxxx@163.com

mail.passwd=xxxxxxxx

mail.from=xxxxxx@163.com

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!

}

ModelAndView view = new ModelAndView("emailResult");

view.addObject("result", result);

return view;

}

}

mail form：

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("zhangfl85@126.com");

mimeMessageHelper.setFrom("zhangfl85@163.com");

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();

}
