spring mail的使用

因为项目的要求,所以做了个邮件发送的功能,但是使用javaMail的话太麻烦了,还需要自己去适配服务器,进行验证,所以就选用了spring的mail功能.因为现在的框架是ssh的,所以就把他做成了模块.下面开始.
首先需要保证要有mail.jar,activation.jar,spring.jar.
然后就是对spring的集成,发代码吧,首先是spring的配置文件,因为我使用了properties文件,所以直接读取文件,配置文件这里要注意下,每条属性后面一定不要跟空格,不然会就会找不到smtp服务器,我就是在这里中招的！

#user is  the sender name;
#password is the sender password;
#auth is allow grant for the mailServices.  default value is true
#smtp.com is the mailService's address
mail.user=***
mail.password=****
mail.auth=true
smtp.com=smtp.163.com
mail.timeout=25000

下面的是我两个类是实现:MailService类

import javax.mail.internet.MimeMessage;

import org.springframework.mail.SimpleMailMessage;


public interface  MailService {
	public void sendMail(SimpleMailMessage smm);
	public void sendMail(MimeMessage  mm);
	public MimeMessage getMimeMessage();
}

MailServiceImpl类

import javax.mail.internet.MimeMessage;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

import com.magus.mail.service.MailService;

public class MailServiceImpl implements MailService {
	private JavaMailSender mailSend;
	
	public JavaMailSender getMailSend() {
		return mailSend;
	}

	public void setMailSend(JavaMailSender mailSend) {
		this.mailSend = mailSend;
	}

	@Override
	public void sendMail(SimpleMailMessage smm) {
		mailSend.send(smm);
	}

	@Override
	public void sendMail(MimeMessage mm) {
		mailSend.send(mm);
	}

	@Override
	public MimeMessage getMimeMessage() {
		return mailSend.createMimeMessage();
	}

}

发送邮件的action类:MailAction

import java.io.File;
import java.io.UnsupportedEncodingException;
import java.util.List;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeUtility;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.MimeMessageHelper;

import com.magus.mail.service.MailService;

public class MailAction {
	private MailService mailService;
	
	/**
	 * 普通邮件发送,sendTo收件者地址,sendSubject邮件主题,sendContent邮件内容<br/>
	 * 注:发送者需要在mailSend.properties文件里面配置<br/>
	 * @param sendTo
	 * @param sendSubject
	 * @param sendContent
	 * @return
	 */
	public void sendMail(String sendTo,String sendSubject,String sendContent){
		SimpleMailMessage smm=new SimpleMailMessage();
		smm.setTo(sendTo);
		smm.setSubject(sendSubject);
		smm.setText(sendContent);
		mailService.sendMail(smm);
	}
	
	/**
	 * 带HTML格式的邮件发送,sendTo收件者地址,sendSubject邮件主题<br/>
	 * sendContent邮件内容,flag为是否发送HTML格式邮件:true是,false不是<br/>
	 * 注:发送者需要在mailSend.properties文件里面配置 <br/>
	 * @param sendTo
	 * @param sendSubject
	 * @param sendContent
	 * @param flag
	 * @return
	 */
	public void sendMailHtml(String sendTo,String sendSubject,String sendContent,boolean flag){
		MimeMessage mimiMail=mailService.getMimeMessage();
		try {
			MimeMessageHelper mHelp=new MimeMessageHelper(mimiMail,true,"utf-8");
			mHelp.setTo(sendTo);
			mHelp.setSubject(sendSubject);
			mHelp.setText(sendContent,flag);
			mailService.sendMail(mimiMail);
		} catch (MessagingException e) {
			e.printStackTrace();
		}
	}
	
	/**
	 * 带HTML格式的邮件发送,sendTo收件者地址,sendSubject邮件主题<br/>
	 * sendContent邮件内容,flag为是否发送HTML格式邮件:true是,false不是<br/>
	 * List<File>表示需要发送的附件<br/>
	 * 注:发送者需要在mailSend.properties文件里面配置 <br/> 
	 * @param sendTo
	 * @param sendSubject
	 * @param sendContent
	 * @param flag
	 * @param l
	 * @return
	 */
	public void sendMailHtmlByAttach(String sendTo,String sendSubject,String sendContent,boolean flag,List<File> f){
		MimeMessage mimiMail=mailService.getMimeMessage();
		try {
			MimeMessageHelper mHelp=new MimeMessageHelper(mimiMail,true,"utf-8");
			mHelp.setTo(sendTo);
			mHelp.setSubject(sendSubject);
			mHelp.setText(sendContent,flag);
			for(int i=0;i<f.size();i++){
				File file=f.get(i);
				String filename=file.getName();
				mHelp.addAttachment(MimeUtility.encodeWord(filename), file);
			}
			mailService.sendMail(mimiMail);
		} catch (MessagingException e) {
			e.printStackTrace();
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	public MailService getMailService() {
		return mailService;
	}

	public void setMailService(MailService mailService) {
		this.mailService = mailService;
	}
}

这些做完之后基本上就已经成型了!
给出个测试方法

public static void main(String[] args) {
		
		args=new String[]{"/mail-service.xml"};
		BeanFactory factory=new ClassPathXmlApplicationContext(args);
		MailAction wiq=(MailAction) factory.getBean("mailAction");
		File f=new File("H:\\path.txt");
		List<File> l=new ArrayList<File>();
		l.add(f);
		wiq.sendMailHtmlByAttach("*****@qq.com", "test", "this is a test mail",false,l);
}

这个模块胜在灵活度高,可以在这个基础上安排定时器(例如定时发送邮件),下面也有代码可以下载
