SpringBoot邮件发送

这篇文章介绍springboot的邮件发送。

由于很简单就没有分出server和imp之类，只是在controller简单写个方法进行测试。

首先pom文件加入spring-boot-starter-mail，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>


</project>

接下来是application.properties，里面包含发送邮箱的地址，账号密码，接信地址，由于只是测试，所以都是固定写死的，如果项目中需要，可以根据自行情况进行修改。

##端口号
server.port=8888

##这里根据自己的情况填写
##邮箱服务器地址
##QQ smtp.qq.com
##sina smtp.sina.cn
##aliyun smtp.aliyun.com
##163 smtp.163.com
spring.mail.host=smtp.aliyun.com
##邮箱用户名
[email protected]
##邮箱密码（注意：qq邮箱应该使用独立密码，去qq邮箱设置里面获取）
spring.mail.password=******
##编码格式
spring.mail.default-encoding=UTF-8

##发送邮件地址
[email protected]
##接收邮件地址
[email protected]

然后先展示一下controller的完整代码：

package com.dalaoyang.controller;

import org.springframework.web.bind.annotation.RestController;

import javax.mail.MessagingException;

    @RequestMapping("/sendMail")
    public String sendMail() {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(sender);
        message.setTo(receiver);
        message.setSubject("大老杨");
        message.setText("你好你好你好！");
        try {
            javaMailSender.send(message);
            logger.info("简单邮件已经发送。");
        } catch (Exception e) {

        }
        return "success";
    }

    @RequestMapping("/sendHtmlMail")
    public String testHtmlMail() {
        String content="<html>\n" +
                "<body>\n" +
                "    <h3>hello world ! 这是一封Html邮件!</h3>\n" +
                "</body>\n" +
                "</html>";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            //true表示需要创建一个multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);

     * @email [email protected]

     * @param
     * @return
     */
    @RequestMapping("/sendFilesMail")
    public String sendFilesMail() {
        String filePath="/Users/dalaoyang/Downloads/article_tag.sql";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(sender);

            FileSystemResource file = new FileSystemResource(new File(filePath));
            String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
            helper.addAttachment(fileName, file);

            javaMailSender.send(message);

        } catch (MessagingException e) {
            logger.error("发送带附件的邮件时发生异常！", e);
        }
        return "success";
    }

    /* *

    @RequestMapping("/sendInlineResourceMail")
    public String sendInlineResourceMail() {
        String Id = "dalaoyang12138";
        String content="<html><body>这是有图片的邮件：<img src=\'cid:" + Id + "\' ></body></html>";
        String imgPath = "/Users/dalaoyang/Downloads/dalaoyang.jpeg";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(sender);
            helper.setTo(receiver);
            helper.setSubject("这是有图片的邮件");
            helper.setText(content, true);

            FileSystemResource res = new FileSystemResource(new File(imgPath));
            helper.addInline(Id, res);

            javaMailSender.send(message);
            logger.info("嵌入静态资源的邮件已经发送。");
        } catch (MessagingException e) {
            logger.error("发送嵌入静态资源的邮件时发生异常！", e);
        }
        return "success";
    }
}

然后一点一点来，本文分4种情况：

1.发送简单的文本邮件

/* *
     * @Description  http://localhost:8888/sendMail
     * @author dalaoyang
     * @email [email protected]
     * @method 发送文本邮件
     * @date
     * @param
     * @return
     */
    @RequestMapping("/sendMail")
    public String sendMail() {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(sender);
        message.setTo(receiver);
        message.setSubject("大老杨");
        message.setText("你好你好你好！");
        try {
            javaMailSender.send(message);
            logger.info("简单邮件已经发送。");
        } catch (Exception e) {
            logger.error("发送简单邮件时发生异常！", e);
        }
        return "success";
    }

访问

http://localhost:8888/sendMail

，可以看到页面上显示success，在去看邮箱可以看到如下图，证明发送成功

2.发送html邮件

/* *
     * @Description  http://localhost:8888/sendHtmlMail

     * @email [email protected]
     * @method 发送html邮件
     * @date
     * @param
     * @return
     */
    @RequestMapping("/sendHtmlMail")
    public String testHtmlMail() {
        String content="<html>\n" +
                "<body>\n" +
                "    <h3>hello world ! 这是一封Html邮件!</h3>\n" +
                "</body>\n" +
                "</html>";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            //true表示需要创建一个multipart message
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(sender);
            helper.setTo(receiver);
            helper.setSubject("html mail");
            helper.setText(content, true);

            javaMailSender.send(message);
            logger.info("html邮件发送成功");
        } catch (MessagingException e) {
            logger.error("发送html邮件时发生异常！", e);
        }
        return "success";
    }
http://localhost:8888/sendHtmlMail

3.发送附件邮件

/* *
     * @Description http://localhost:8888/sendFilesMail
     * @author dalaoyang
     * @email [email protected]
     * @method 发送附件邮件
     * @date
     * @param
     * @return
     */
    @RequestMapping("/sendFilesMail")
    public String sendFilesMail() {
        String filePath="/Users/dalaoyang/Downloads/article_tag.sql";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(sender);
            helper.setTo(receiver);
            helper.setSubject("附件邮件");
            helper.setText("这是一封带附件的邮件", true);

            FileSystemResource file = new FileSystemResource(new File(filePath));
            String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
            helper.addAttachment(fileName, file);

            javaMailSender.send(message);
            logger.info("带附件的邮件已经发送。");
        } catch (MessagingException e) {
            logger.error("发送带附件的邮件时发生异常！", e);
        }
        return "success";
    }
http://localhost:8888/sendFilesMail

4.发送图片邮件

/* *
     * @Description http://localhost:8888/sendInlineResourceMail
     * @author dalaoyang
     * @email [email protected]
     * @method 发送图片邮件
     * @date
     * @param
     * @return
     */
    @RequestMapping("/sendInlineResourceMail")
    public String sendInlineResourceMail() {
        String Id = "dalaoyang12138";
        String content="<html><body>这是有图片的邮件：<img src=\'cid:" + Id + "\' ></body></html>";
        String imgPath = "/Users/dalaoyang/Downloads/dalaoyang.jpeg";
        MimeMessage message = javaMailSender.createMimeMessage();

        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(sender);
            helper.setTo(receiver);
            helper.setSubject("这是有图片的邮件");
            helper.setText(content, true);

            FileSystemResource res = new FileSystemResource(new File(imgPath));
            helper.addInline(Id, res);

            javaMailSender.send(message);
            logger.info("嵌入静态资源的邮件已经发送。");
        } catch (MessagingException e) {
            logger.error("发送嵌入静态资源的邮件时发生异常！", e);
        }
        return "success";
    }
http://localhost:8888/sendInlineResourceMail
