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">

<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>

<type>pom</type>

</dependencies>
</dependencyManagement>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<dependencies>
<dependency>

<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:
true3、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br/>登录happy.huangjinjin@163.com邮箱
简单邮件
模板邮件
附件邮件
内嵌图片邮件
