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 sender --> 
  <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl" 
    p:host="${mail.host}" p:port="${mail.port}"  
    p:username="${mail.user}" p:password="${mail.passwd}"></bean> 

       
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!<br/><hr/>"+e.getMessage(); 
    } 
    ModelAndView view = new ModelAndView("emailResult"); 
    view.addObject("result", result); 
    return view; 
  } 
} 

mail form:

<form:form action="sendEmail.do" method="post" commandName="newEmail"> 
  <div> 
    <p>   to:<form:input path="to" cssStyle="width:260px;"/> 
      <form:errors path="to" cssStyle="color:red;"/></p> 
    <p>subject:<form:input path="subject" cssStyle="width:260px;"/> 
      <form:errors path="subject" cssStyle="color:red;"/></p> 
    <p>content:<form:textarea path="content" rows="5" cols="60"></form:textarea><br/> 
      <form:errors path="content" cssStyle="color:red;"/></p> 
    <p><input type="submit" value="confirm and send"/></p> 
  </div> 
   
</form: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();
 }
