java邮件开发（转）

原文地址http://blog.youkuaiyun.com/cyh1111/article/details/4349200

1. 首先建立一个简单的邮件Model

 

package com.itmg.tool.email;

 

import java.io.Serializable;

 

public class MailModel implements Serializable {

private static final long serialVersionUID = 1L;

private String subjectText;

private String bodyText;

private String[] receiver;

    private String content_format = "text/html; charset=UTF-8";

    private boolean isdebug = false;

public MailModel() {

// TODO Auto-generated constructor stub

}

public String getBodyText() {

return bodyText;

}

public void setBodyText(String bodyText) {

this.bodyText = bodyText;

}

public String[] getReceiver() {

return receiver;

}

public void setReceiver(String[] receiver) {

this.receiver = receiver;

}

public String getSubjectText() {

return subjectText;

}

public void setSubjectText(String subjectText) {

this.subjectText = subjectText;

}

    public String getContent_format() {

        return content_format;

    }

    public void setContent_format(String content_format) {

        this.content_format = content_format;

    }

public boolean isIsdebug() {

return isdebug;

}

public void setIsdebug(boolean isdebug) {

this.isdebug = isdebug;

}

}

2. 认证

package com.itmg.tool.email;

import javax.mail.Authenticator;

import javax.mail.PasswordAuthentication;

public class PopupAuthenticator extends Authenticator{

String username=null;

      String password=null;

      public PopupAuthenticator(){}

      public PasswordAuthentication performCheck(String user,String pass){

          username = user;

          password = pass;

          return getPasswordAuthenticatio n();

      }

      protected PasswordAuthentication getPasswordAuthenticatio n(){

          return new PasswordAuthentication(username, password);

      }

}

3. 建立发邮件的类

package com.itmg.tool.email;

import java.io.UnsupportedEncodingExcep tion;

import java.util.Date;

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import org.apache.log4j.Logger;

import com.itmg.db.TransServer;

public class SendMail extends Thread{

private static Logger log = Logger.getLogger(SendMail.class.getName()); 

private static final String SMTP_HOST_NAME = "smtp.gmail.com"; //发邮件的服务器

private static final String emailFromAddress = "xxx@gmail.com";

private static final String emailFromAddressPassword = "xxxxx";

private static final String emailTitle = "Exception";//email 的标题名字

private MailModel mailModel;

public SendMail(MailModel mailModel) {

// TODO Auto-generated constructor stub

this.mailModel = mailModel;

}

public void sendMessage() throws MessagingException{

String recipients[] = mailModel.getReceiver();

String subject = mailModel.getSubjectText();

String message = mailModel.getBodyText();

boolean isdebug = mailModel.isIsdebug();

Properties props = System.getProperties();

Session sendMailSession;

props.put("mail.smtp.auth", "true");

props.put("mail.debug", isdebug);

props.put("mail.smtp.host", SMTP_HOST_NAME);

props.put("mail.smtp.user", emailFromAddress);

props.put("mail.smtp.password", emailFromAddressPassword );

PopupAuthenticator popA = new PopupAuthenticator();

PasswordAuthentication pop = popA.performCheck(emailFromAddress, emailFromAddressPassword );

sendMailSession = Session.getInstance(props, popA);

MimeMessage mimeMessage = new MimeMessage(sendMailSession);

try {

mimeMessage.setFrom(new InternetAddress(emailFromAddress, emailTitle,

"UTF-8"));

} catch (UnsupportedEncodingExcep tion e) {

e.printStackTrace();

}

InternetAddress[] addressTo = new InternetAddress[recipients.length];

for (int i = 0; i < recipients.length; i++) {

addressTo[i] = new InternetAddress(recipients[i]);

}

mimeMessage.setRecipients(Message.RecipientType.TO, addressTo);

mimeMessage.setSubject(subject, "UTF-8");

mimeMessage.setContent(message,

mailModel.getContent_format());

mimeMessage.setHeader("Content-Transfer-Encoding", "7bit");

mimeMessage.setSentDate(new Date());

Transport.send(mimeMessage);

log.info("========>the email has been sent out!");

}

public void run()

{

try {

sendMessage();

} catch (Exception e) {

// TODO: handle exception

e.printStackTrace();

}

}

}

4. 负责发邮件的Action

package com.itmg.search.action;

import com.itmg.search.action.base.SearchBaseAction;

import com.itmg.tool.email.MailModel;

import com.itmg.tool.email.SendMail;

import com.itmg.util.TransServerUtil;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.util.ValueStack;

public class SendMailAction extends SearchBaseAction{

     

private static final long serialVersionUID = 1L;

public String execute() throws Exception {

ValueStack valueStack = ActionContext.getContext().getValueStack();

String message = (String)valueStack.findValue("exceptionStack");

MailModel mailModel = new MailModel();

StringBuffer sb = new StringBuffer();

sb.append("RemoteHost"+request.getRemoteHost()+"/r/n");

sb.append("RemoteAddr"+request.getRemoteAddr()+"/r/n");

sb.append("User-Agent:"+request.getHeader("User-Agent")+"/r/n");

sb.append("RefererString:"+request.getHeader("referer")+"/r/n");

sb.append(message);

mailModel.setBodyText(sb.toString());

mailModel.setSubjectText("The API.com server error notice");

mailModel.setReceiver(new String[]{TransServerUtil.ToMeEmail});

mailModel.setContent_format("text/plain;charset=utf-8");

SendMail emailSend = new SendMail(mailModel);

Thread emailThread = new Thread(emailSend);

emailThread.start();

return "index";

}

     

}
