Spring Boot整合邮箱发送邮件实例
作者：it永远的学习者
大家好，本篇文章主要讲的是Spring Boot整合邮箱发送邮件实例，感兴趣的同学赶快来看一看吧，对你有帮助的话记得收藏一下
1. 准备工作
登录进自己的 qq 邮箱获取授权码
设置 – 账户 – POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务
点击开始获取授权码，将授权码保存下来，下面代码整合的时候需要使用
2. 代码整合
创建一个 Spring Boot 项目，引入以下依赖
<!-- email -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
配置文件
server:
port: 8080
spring:
# email 配置
mail:
# SMTP 服务器地址
host: smtp.qq.com
username: # 你的qq 邮箱地址
password: # 授权码，上面从 qq 邮箱官网得到的授权码
port: 587
protocol: smtp
default-encoding: UTF-8
创建一个邮件收件人信息的实体类
/**
* @author lishisen
* @description 邮件收件人信息
* @date 2022/1/9 9:37
**/
@AllArgsConstructor
@NoArgsConstructor
@Data
public class EmailModel implements Serializable {
// 收件人邮箱地址
private String receiveEmailAddress;
// 邮箱主题
private String emailTheme;
// 邮件内容
private String emailContent;
}
创建一个服务提供类，SendEmailService.java
/**
* @author lishisen
* @description 邮件发送服务类
* @date 2022/1/9 9:40
**/
@Slf4j
@Component
public class SendEmailService {
@Autowired
private JavaMailSender javaMailSender;
@Autowired
private JavaMailSenderImpl javaMailSenderImpl;
// 发送者地址
private String posterAddress = "1876419736@qq.com";
// 发送者名称
private String posterName = "测试邮件发送";
/**
* 文本发送
**/
public void sendEmailAsText(final EmailModel emailModel) {
System.out.println(emailModel.toString());
MimeMessagePreparator mimeMessagePreparator = mimeMessage -> {
mimeMessage.setFrom(posterAddress);
mimeMessage.setRecipients(Message.RecipientType.TO, emailModel.getReceiveEmailAddress());
mimeMessage.setText("发送者地址：" + posterAddress + '\n'
+ "发送者名称：" + posterName + '\n'
+ "内容：" + emailModel.getEmailContent());
};
try {
this.javaMailSender.send(mimeMessagePreparator);
log.info("邮箱已返送至[{}]邮箱！", emailModel.getReceiveEmailAddress());
} catch (MailException e) {
log.error("邮箱异常：{}", e);
}
}
/**
* html 网页发送
* 该方法为同步方法
**/
public void sendEmailAsSysExceptionHtml(final EmailModel emailModel, String info) {
MimeMessage mimeMessage = javaMailSenderImpl.createMimeMessage();
MimeMessageHelper mimeMessageHelper;
try {
mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
mimeMessageHelper.setFrom(posterAddress);
mimeMessageHelper.setTo(emailModel.getReceiveEmailAddress());
mimeMessageHelper.setSubject(emailModel.getEmailTheme());
mimeMessageHelper.setText(
"<!DOCTYPE html>\n" +
"<html lang=\"en\">\n" +
"<head>\n" +
" <meta charset=\"UTF-8\">\n" +
" <title>Title</title>\n" +
"</head>\n" +
"<body>\n" +
"<h2>" + info + "</h2>\n" +
"<h3>您的验证码为：<span style='color: red'" + ">" +
emailModel.getEmailContent() +
"</span> " + "，请在 5 分钟内进行验证</h3>\n" +
"</body>\n" +
"</html>"
, true);
this.javaMailSender.send(mimeMessage);
log.info("邮箱已返送至[{}]邮箱！", emailModel.getReceiveEmailAddress());
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
测试使用
@Autowired
private SendEmailService sendEmailService;
@Test
public void sendMailTest() {
// 创建收件人实体类，封装收件人的信息
EmailModel emailModel = new EmailModel();
emailModel.setReceiveEmailAddress("18xxxxxqq.com");
emailModel.setEmailTheme("测试发送");
emailModel.setEmailContent("测试发送邮箱主体信息内容");
// 调用发送服务方法执行发送任务
sendEmailService.sendEmailAsText(emailModel);
System.out.println("邮件发送成功");
}
