Java的Spring框架中实现发送邮件功能的核心代码示例
作者：dyyaries
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();
}
