发送简单的邮件
@RestController
@RequestMapping("/email")
public class EmailController {
@Autowired
private JavaMailSender jms;
@Value("${spring.mail.username}")
private String from;
@RequestMapping("sendSimpleEmail")
public String sendSimpleEmail() {
try {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
// 接收地址
message.setTo("XXX@onmicrosoft.com");
// 标题
message.setSubject("一封简单的邮件");
// 内容
message.setText("使用Spring Boot发送简单邮件。");
jms.send(message);
return "发送成功";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
}
}
}
发送HTML格式的邮件
@RequestMapping("sendHtmlEmail")
public String sendHtmlEmail() {
MimeMessage message = null;
try {
message = jms.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo("XXX@onmicrosoft.com");
helper.setSubject("一封HTML格式的邮件");
// 带HTML格式的内容
StringBuffer sb = new StringBuffer("<p style='color:#42b983'>使用Spring Boot发送HTML格式邮件。</p>");
helper.setText(sb.toString(), true);
jms.send(message);
return "发送成功";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
}
}
发送带附件的邮件
@RequestMapping("sendAttachmentsMail")
public String sendAttachmentsMail() {
MimeMessage message = null;
try {
message = jms.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo("XXX@onmicrosoft.com");
helper.setSubject("一封带附件的邮件");
helper.setText("详情参见附件内容！");
// 传入附件
File file = ResourceUtils.getFile("classpath:static/file/附件.docx");
helper.addAttachment("附件.docx", file);
jms.send(message);
return "发送成功";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
}
}
发送带静态资源的邮件
@RequestMapping("sendInlineMail")
public String sendInlineMail() {
MimeMessage message = null;
try {
message = jms.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo("XXX@onmicrosoft.com");
helper.setSubject("一封带静态资源的邮件"); // 标题
helper.setText("<html><body>图片：<img src='cid:img'/></body></html>", true);
// 传入附件
File file = ResourceUtils.getFile("classpath:static/img/img.png");
helper.addInline("img", file);
jms.send(message);
return "发送成功";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
}
}
使用模板发送邮件
<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8" />
<title>模板</title>
</head>
<body>
您好，您的验证码为<span th:text="${code}"></span>，请在两分钟内使用完成操作。
</body>
</html>
@Autowired
private TemplateEngine templateEngine;
@RequestMapping("sendTemplateEmail")
public String sendTemplateEmail(String code) {
MimeMessage message = null;
try {
message = jms.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo("XXX@onmicrosoft.com"); // 接收地址
helper.setSubject("邮件摸板测试"); // 标题
// 处理邮件模板
Context context = new Context();
context.setVariable("code", code);
String template = templateEngine.process("emailTemplate", context);
helper.setText(template, true);
jms.send(message);
return "发送成功";
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();
}
