  前段时间在工作中用到了邮件发送监控的报警信息,今天在这个记录一下JavaMail的邮件工具类。

  下边为用到的JavaMail的jar包的pom依赖。这里用的是JavaMail的1.4.6的版本。

<dependency>
  <groupId>javax.mail</groupId>
  <artifactId>mail</artifactId>
  <version>1.4.6</version>
</dependency>

  这里是工具类中的用到的邮件的一些参数对象的实体类。  

package com.juihai.entity;

import java.util.Arrays;

public class EmailTO {
    private String title;//邮件主题
    private String content;//邮件内容
    private String sender;//发件人账号
    private String password;//发件人密码
    private String host;//发件邮箱服务器
    private String[] toAdress;//收件人地址
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getContent() {
        return content;
    }
    public void setContent(String content) {
        this.content = content;
    }
    public String getSender() {
        return sender;
    }
    public void setSender(String sender) {
        this.sender = sender;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getHost() {
        return host;
    }
    public void setHost(String host) {
        this.host = host;
    }
    public String[] getToAdress() {
        return toAdress;
    }
    public void setToAdress(String[] toAdress) {
        this.toAdress = toAdress;
    }
    @Override
    public String toString() {
        return "EmailTO [title=" + title + ", content=" + content + ", sender="
                + sender + ", password=" + password + ", host=" + host
                + ", toAdress=" + Arrays.toString(toAdress) + "]";
    }
    
    
}

  这里是就是发送Email的工具类。具体说明件代码中的注释。

public class SendEmailUtils {

    private static Logger log = Logger.getLogger(SendEmailUtils.class);

    public static boolean send(EmailTO to) throws GeneralSecurityException{

        final String user = to.getSender();
        final String password = to.getPassword();
        log.info("SendEmailUtils >>>> Start Send Mail");
        Properties properties = System.getProperties();// 获取系统属性
        properties.setProperty("mail.smtp.host", to.getHost());// 设置邮件服务器 "smtp.163.com",这是发件人的邮箱服务器
        properties.put("mail.smtp.auth", "true");
        String senderNick = null;
     
     //部分邮箱服务器需要开启SSL验证才可以发送邮件,需要的话,开启注释即可 
/*MailSSLSocketFactory sf = new MailSSLSocketFactory();// SSL验证 begin sf.setTrustAllHosts(true); properties.put("mail.smtp.ssl.enable", "true"); properties.put("mail.smtp.ssl.socketFactory", sf);// SSL验证 end*/ Session session = Session.getDefaultInstance(properties, new Authenticator() { public PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(user, password); // 发件人邮件用户名、密码 } }); try { MimeMessage message = new MimeMessage(session);// 创建默认的 MimeMessage对象 senderNick = javax.mail.internet.MimeUtility.encodeText("Juihai");//设置发件人昵称 message.setFrom(new InternetAddress(senderNick+"<"+user+">")); //message.addRecipient(Message.RecipientType.TO,new InternetAddress());//创建单个收件人 String[] tos = to.getToAdress();//创建多个收件人 if (tos != null && tos.length != 0) { InternetAddress[] toAddress = new InternetAddress[tos.length]; for (int i = 0; i < tos.length; i++) { toAddress[i] = new InternetAddress(tos[i]); } message.setRecipients(Message.RecipientType.TO, toAddress); } message.setSubject(to.getTitle());//设置邮件主题 //message.setText(content);//发送纯文本内容 message.setContent(to.getContent(), "text/html;charset=utf-8");//发送html邮件内容 Transport.send(message);//发送Email log.info(" SendEmailUtils邮件发送成功"); return true; }catch (MessagingException mex) { mex.printStackTrace(); log.info(" >>>>SendEmailUtils邮件发送失败"+mex); } catch (UnsupportedEncodingException e) { log.info(" >>>>SendEmailUtils邮件发送失败-设置发件人昵称error"+e); e.printStackTrace(); } return false; } }
