Java发送邮件----自己封装的方法

发送邮件的封装类：

package com.email;

import java.util.Properties;

import javax.mail.Authenticator;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import org.springframework.mail.javamail.MimeMessageHelper;

public class Email {

public MimeMessage message;

public MimeMessageHelper creatEmail(String host, String port, String user, String pw) throws MessagingException{

// 创建Properties 类用于记录邮箱的一些属性

final Properties props = new Properties();

// 表示SMTP发送邮件，必须进行身份验证

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

//开启ttl加密

props.put("mail.smtp.starttls.enable", "true");

//此处填写SMTP服务器

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

//端口号，QQ邮箱给出了两个端口，但是另一个我一直使用不了，所以就给出这一个587

props.put("mail.smtp.port", port);

// 此处填写你的账号

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

// 此处的密码就是前面说的16位STMP口令

props.put("mail.password", pw);

// 构建授权信息，用于进行SMTP进行身份验证

Authenticator authenticator = new Authenticator() {

protected PasswordAuthentication getPasswordAuthentication() {

// 用户名、密码

String userName = props.getProperty("mail.user");

String password = props.getProperty("mail.password");

return new PasswordAuthentication(userName, password);

}

};

// 使用环境属性和授权信息，创建邮件会话

Session mailSession = Session.getInstance(props, authenticator);

// 创建邮件消息

message = new MimeMessage(mailSession);

MimeMessageHelper helper = null;

// 设置发件人

InternetAddress form = new InternetAddress(

props.getProperty("mail.user"));

try {

helper = new MimeMessageHelper(message,true,"utf-8");

helper.setFrom(form);

} catch (MessagingException e) {

e.printStackTrace();

}

return helper;

}

}

调用方法：发送邮件

@RequestMapping(value = "/sendEmail", method = RequestMethod.POST)

    @ResponseBody

    public ArrayList sendEmail(@RequestBody HashMap body) throws MessagingException{

        Email email = new Email();

        MimeMessageHelper msgHelper = email.creatEmail("邮箱发信服务器地址", "端口", "发件邮箱", "密码");

        msgHelper.setTo((String)body.get("toEmail"));

        msgHelper.setSubject("主题");

        msgHelper.setText("内容");

        Transport.send(email.message);

        ArrayList ls = new ArrayList();

        ls.add("OK");

        return ls;

    }
