问答社区-[注册]发送邮件
1.邮箱设置
开启SMTP服务并保存
2. Spring Email
2.1导入Jar包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
<version>2.2.2.RELEASE</version>
</dependency>2.2邮箱参数配置
#MailProperties spring.mail.host=smtp.sina.com spring.mail.port=465 spring.mail.username=niukexiangmu@sina.com spring.mail.password=asdfasdfasdasd spring.mail.protocol=smtps #采用ssl安全连接 spring.mail.properties.mail.stmp.ssl.enable = true
2.3使用JavaMailSender发送邮件
@Component
public class MailClient {
private static final Logger logger = LoggerFactory.getLogger(MailClient.class);
@Autowired
private JavaMailSender mailSender;
@Value("${spring.mail.username}")
private String from;
public void sendMail(String to, String subject, String content) {
try {
//这里的message相当于一个邮件模板，但是是空的，需要helper去添加信息
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
mailSender.send(helper.getMimeMessage());
} catch (MessagingException e) {
logger.error("发送邮件失败" + e.getMessage());
}
}
}3.Thymeleaf模板引擎
template中创建demo.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>邮件实例</title>
</head>
<body>
<p>欢迎你,<span style="color:red;" th:text="${username}"></span></p>
</body>
</html>@Test
public void testHtmlMail(){
Context context = new Context();
context.setVariable("username","heihei");
//使用上文创建的模板引擎
String content = templateEngine.process("/mail/demo",context);
System.out.println(content);
mailClient.sendMail("1009156204@qq.com","html",content);
}
