Spring发送邮件简单试用

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=[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!<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>
