java免費發送郵件實現

java免費發送郵件實現

現在項目上線一段時間了，希望能夠在項目中出現異常後郵件通知給相關開發人員。我從網上找了大量的第三方介面（需要花錢）和發送郵件demo。最後選擇了一個只需要引入一個jar包和一個工具類的實現，不需要設定檔，具體的工具類代碼如下：

package com.evan.mail;import java.util.Date;import java.util.Properties;import javax.mail.Authenticator;import javax.mail.Message;import javax.mail.MessagingException;import javax.mail.PasswordAuthentication;import javax.mail.Session;import javax.mail.Transport;import javax.mail.internet.AddressException;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeMessage;public class SendMail {    public static void main(String[] args) {        MessageVo mv = new MessageVo();        mv.setSubject("很遺憾，您的程式出bug了"+new Date());        mv.setText("bug的具體內容為："+"null 指標異常");        mv.setToMailAddress("[email protected]");        sendMail(mv);    }    public static void sendMail(MessageVo mv ){        final String username = "[email protected]";        final String password = "evan0202";        boolean isSSL = true;        String host = "smtp.163.com";        int port = 465;        boolean isAuth = true;        String from = "[email protected]";        Properties props = new Properties();        props.put("mail.smtp.ssl.enable", isSSL);        props.put("mail.smtp.host", host);        props.put("mail.smtp.port", port);        props.put("mail.smtp.auth", isAuth);        Session session = Session.getDefaultInstance(props, new Authenticator() {            @Override            protected PasswordAuthentication getPasswordAuthentication() {                return new PasswordAuthentication(username, password);            }        });        try {            Message message = new MimeMessage(session);            message.setFrom(new InternetAddress(from));            message.setSubject(mv.getSubject());            message.setText(mv.getText());            message.addRecipient(Message.RecipientType.TO, new InternetAddress(mv.getToMailAddress()));            Transport.send(message);        } catch (AddressException e) {            e.printStackTrace();        } catch (MessagingException e) {            e.printStackTrace();        }        System.out.println("發送完畢！");    }}

需要注意的是：
1、寄件者郵箱沒有開通pop3/SMTP協議需要開通
2、寄件者163郵件發送次數多了，163會提示說帳號有安全威脅之類，需要你在163郵箱設定授權
3、項目中需要用到的jar是mail-1.4.5.jar

直接將項目匯入eclipse，運行main方法即可完成發送郵件
