25、springboot发送邮件

2024-03-16 12:21:34

虽然现在短信验证已经最流行也是最常用的验证方式；但是邮件验证还是必不可少，依然是网站的必备功能之一。什么注册验证，忘记密码或者是给用户发送营销信息都是可以使用邮件发送功能的。最早期使用JavaMail的相关api来进行发送邮件的功能开发，后来spring整合了JavaMail的相关api推出了JavaMailSender更加简化了邮件发送的代码编写，现在springboot对此进行了封装就有了现在的spring-boot-starter-mail。

1、新建项目sc-mail，对应的pom.xml文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

 

<groupId>spring-cloud</groupId>

<artifactId>sc-mail</artifactId>

<version>0.0.1-SNAPSHOT</version>

<packaging>jar</packaging>

 

<name>sc-mail</name>

<url>http://maven.apache.org</url>

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.4.RELEASE</version>

</parent>

 

<dependencyManagement>

<dependencies>

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-dependencies</artifactId>

<version>Finchley.RELEASE</version>

<type>pom</type>

<scope>import</scope>

</dependency>

 

</dependencies>

</dependencyManagement>

 

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

</properties>

 

<dependencies>

 

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-mail</artifactId>

</dependency>

 

 

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-test</artifactId>

<scope>test</scope>

</dependency>

 

</dependencies>

</project>

2、新建配置文件application.yml

spring:

  application:

    name: sc-mail

  mail:

    host: smtp.qq.com #邮箱服务器地址

    port: 465

    username: 515768476@qq.com #用户名

    password: vfcqhwsnnwugbhcx #密码 （改成自己的密码）

    default-encoding: UTF-8

    properties:

      mail:

        smtp:

          ssl:

            enable:

              true

3、新建邮件发送服务类

package sc.mail.service.impl;

 

import java.io.File;

 

import javax.mail.internet.MimeMessage;

 

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.core.io.FileSystemResource;

import org.springframework.mail.SimpleMailMessage;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.MimeMessageHelper;

import org.springframework.stereotype.Service;

 

import sc.mail.service.MailService;

 

@Service

public class MailServiceImpl implements MailService {

 

private final Logger logger = LoggerFactory.getLogger(this.getClass());

 

@Autowired

private JavaMailSender mailSender;

 

/**

 * 文本

 * @param from

 * @param to

 * @param subject

 * @param content

 */

@Override

public void sendSimpleMail(String from, String to, String subject, String content) {

SimpleMailMessage message = new SimpleMailMessage();

message.setFrom(from);

message.setTo(to);

message.setSubject(subject);

message.setText(content);

try {

mailSender.send(message);

logger.info("simple mail had send。");

} catch (Exception e) {

logger.error("send mail error", e);

}

}

 

/**

 * @param from

 * @param to

 * @param subject

 * @param content

 */

public void sendTemplateMail(String from, String to, String subject, String content) {

    MimeMessage message = mailSender.createMimeMessage();

    try {

        //true表示需要创建一个multipart message

        MimeMessageHelper helper = new MimeMessageHelper(message, true);

        helper.setFrom(from);

        helper.setTo(to);

        helper.setSubject(subject);

        helper.setText(content, true);

        mailSender.send(message);

        logger.info("send template success");

    } catch (Exception e) {

        logger.error("send template eror", e);

    }

}

 

 

/**

 * 附件

 *

 * @param from

 * @param to

 * @param subject

 * @param content

 * @param filePath

 */

public void sendAttachmentsMail(String from, String to, String subject, String content, String filePath){

    MimeMessage message = mailSender.createMimeMessage();

    try {

        MimeMessageHelper helper = new MimeMessageHelper(message, true);

        helper.setFrom(from);

        helper.setTo(to);

        helper.setSubject(subject);

        helper.setText(content, true);

        FileSystemResource file = new FileSystemResource(new File(filePath));

        String fileName = filePath.substring(filePath.lastIndexOf(File.separator));

        helper.addAttachment(fileName, file);

        mailSender.send(message);

        logger.info("send mail with attach success。");

    } catch (Exception e) {

        logger.error("send mail with attach success", e);

    }

}

 

 

/**

 * 发送内嵌图片

 *

 * @param from

 * @param to

 * @param subject

 * @param content

 * @param imgPath

 * @param imgId

 */

public void sendInlineResourceMail(String from, String to, String subject, String content,

String imgPath, String imgId){

    MimeMessage message = mailSender.createMimeMessage();

    try {

        MimeMessageHelper helper = new MimeMessageHelper(message, true);

        helper.setFrom(from);

        helper.setTo(to);

        helper.setSubject(subject);

        helper.setText(content, true);

        FileSystemResource res = new FileSystemResource(new File(imgPath));

        helper.addInline(imgId, res);

        mailSender.send(message);

        logger.info("send inner resources success。");

    } catch (Exception e) {

        logger.error("send inner resources fail", e);

    }

}

 

}

4、新建测试类

package sc.mail;

 

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

 

import sc.mail.service.MailService;

 

@RunWith(SpringRunner.class)

@SpringBootTest

public class MailSendTest {

 

@Autowired

private MailService mailService;

 

@Test

public void sendSimpleMailTest() {

mailService.sendSimpleMail("515768476@qq.com", "happy.huangjinjin@163.com",

"sendSimpleMailTest", "sendSimpleMailTest from 515768476@qq.com");

}

 

@Test

public void sendTemplateMailTest() {

String html = "<html><body>"

+ " <div> "

+ "    sendTemplateMailTest from 515768476@qq.com </br>"

+ "    <b>这是模板邮件</b>"

+ "</div>"

+ "</body></html>";

mailService.sendTemplateMail("515768476@qq.com", "happy.huangjinjin@163.com",

"sendTemplateMailTest", html);

}

 

@Test

public void sendAttachmentsMailTest() {

String filePath = "D:\\springcloudws\\sc-mail\\src\\main\\java\\sc\\mail\\service\\impl\\MailServiceImpl.java";

mailService.sendAttachmentsMail("515768476@qq.com", "happy.huangjinjin@163.com",

"sendAttachmentsMailTest", "sendAttachmentsMailTest from 515768476@qq.com", filePath);

}

 

@Test

public void sendInlineResourceMailTest() {

String imgId = "img1";

 

String content = "<html><body>"

+ "sendInlineResourceMailTest：<img src=\'cid:" + imgId + "\' >"

+ "</body></html>";

 

String imgPath = "D:\\springcloudws\\sc-mail\\src\\main\\resources\\20181015223228.jpg";

 

mailService.sendInlineResourceMail("515768476@qq.com", "happy.huangjinjin@163.com",

"sendAttachmentsMailTest", content, imgPath, imgId);

}

 

}

5、运行测试类验证是否发送邮件成功
