春季:发送HTML邮件 [英] Spring: Send HTML mail
问题描述
我想创建一个使用Spring电子邮件发送HTML邮件的服务，其中 MimeMessage .这是我的服务:
I want to create a service to send an HTML mail using Spring email with MimeMessage. Here is my service:
public void sendHtmlEmail(String receiver,String Subject, String htmlBody) throws MessagingException {
MimeMessage msg = javaMailSender.createMimeMessage();
// true = multipart message
MimeMessageHelper helper = new MimeMessageHelper(msg, false);
helper.setTo(receiver);
helper.setSubject(Subject);
// true = text/html
helper.setText(htmlBody, true);
javaMailSender.send(msg);
}
The problem is that I don't receive an email in html but tags in html,knowing that I put true in the method setText() ! the email I send is displayed in plain html text like following
<html><h1>some text !</h1></html>

这是application.properties:
here's the application.properties :
spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=username
spring.mail.password=password
# Other properties
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.connectiontimeout=5000
spring.mail.properties.mail.smtp.timeout=5000
spring.mail.properties.mail.smtp.writetimeout=5000
# TLS , port 587
spring.mail.properties.mail.smtp.starttls.enable=true
和控制器
@PostMapping("/htmlMail")
public String sendHtmlMail(@RequestBody MailDTO mail) {
mailService.sendHtmlEmail(mail.getReceiver(),mail.getSubject(),mail.getHtmlbody());
return "html E-Mail Sent ! ";
}
推荐答案
有时所需的参数不存在，因此会出现错误.在您的问题中，没有给出完整的代码或错误提示，因此我在途中进行了描述.
Sometime required parameter is not there so it gives an error. In your question not whole code or error snep is given so i describe on my way.
首先检查以下两点，
- 提供了所有必需的配置数据.
- 您的电子邮件ID必须具有使用您的应用程序发送邮件的权限(如果使用的话，请在您的gmail帐户中允许安全性较低的应用程序").

代码段
@Autowired
JavaMailSender mailSender;
public void sendMail(String to, String subject, String content, boolean
isMultipart, boolean isHtml){
MimeMessage mimeMessage = mailSender.createMimeMessage();
JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost(EMAIL_HOST);
mailSender.setPort(EMAIL_PORT);
mailSender.setUsername(EMAIL_USERNAME);
mailSender.setPassword(EMAIL_PASSWORD);
Properties properties = mailSender.getJavaMailProperties();
properties.put("mail.smtp.starttls.enable", Boolean.TRUE);
properties.put("mail.transport.protocol", "smtp");
properties.put("mail.smtp.auth", Boolean.TRUE);
properties.put("mail.smtp.starttls.required", Boolean.TRUE);
properties.put("mail.smtp.ssl.enable", Boolean.FALSE);
properties.put("mail.test-connection", Boolean.TRUE);
properties.put("mail.debug", Boolean.TRUE);
mailSender.setJavaMailProperties(properties);
try {
MimeMessageHelper messageHelper = new MimeMessageHelper(mimeMessage, isMultipart, "UTF-8");
messageHelper.setFrom(USER_EMAIL);
messageHelper.setTo(to);
messageHelper.setSubject(subject);
messageHelper.setText(content, isHtml);
mailSender.send(mimeMessage);
} catch (Exception ex) {
log.warn("Email could not be sent to user '{}': {}", to, ex.getMessage());
}
}
通话
@Async
public void sendTestingMail(String mail) {
String subject = "Test mail from Project Management System";
String content = "<h1>Be happy, Enjoy Life...!!!</h1>";
sendMail(mail, subject, content, false, true);
}
通过电子邮件发送一次设置的配置，并使用多个位置，因此请尝试进行单个完整设置.
Email kind of configuration you set up once and use multiple place so try to do single full setup.
