基於springboot發郵件
阿新 • • 發佈：2018-12-09
1.新增pom對郵件的支援
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>2.配置郵件引數
spring.mail.host=smtp.qq.com [email protected] spring.mail.password=。。。。 //授權碼 spring.mail.default-encoding=utf-8
3.傳送簡單文字郵件
@Value("${spring.mail.username}") private String from; //傳送人 @Autowired private JavaMailSender mailSender; public void sendSimpleMail(String to,String subject,String content) { SimpleMailMessage simpleMailMessage = new SimpleMailMessage(); simpleMailMessage.setTo(to);//接收人 simpleMailMessage.setSubject(subject); //郵件主題 simpleMailMessage.setText(content);//郵件內容 simpleMailMessage.setFrom(from);//傳送人 mailSender.send(simpleMailMessage); }
4.傳送帶html的郵件
public void sendHtmlMain(String to,String subject,String content) throws Exception {
MimeMessage mssage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mssage,true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true); //true為使用html
helper.setFrom(from);
mailSender.send(mssage);
}
@Test
public void testHtmlMail() throws Exception {
String to=" 5.傳送帶有附件的郵件
public void sendAttachmentsMail(String to,String subject,String content,String filePath) throws Exception {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
helper.setFrom(from);
//filepath 為附件的路徑
FileSystemResource fileSystemResource = new FileSystemResource(new File(filePath));
String fileName=fileSystemResource.getFilename();
helper.addAttachment(fileName, fileSystemResource);
mailSender.send(message);
}
//帶附件的
@Test
public void testAttachmentsMail() throws Exception {
String to="[email protected]";
String subject="附件的郵件";
String content="<html>\n"+
"<body>\n"+
"<h3>hello 你好 附件 郵件</h3>\n"+
"</body>\n"+
"</html>";
String filePath="F:\\99.GIF";
mailService.sendAttachmentsMail(to, subject, content,filePath);
}5.傳送html裡面有圖片的郵件
public void sendInLinResourceMail(String to,String subject,String content,String rscPath,String rscId) throws Exception {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
helper.setFrom(from);
FileSystemResource fileSystemResource = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, fileSystemResource);
mailSender.send(message);
}
//圖片在html中的
@Test
public void testInLinResourceMail() throws Exception {
String to="[email protected]";
String subject="圖片在html中的郵件";
String rscId="wq001";
String filePath="F:\\99.GIF";
String content="<html>\n"+
"<body>\n"+
"<h3>hello 圖片在html中的 郵件</h3>\n"+
"<img src='cid:"+rscId+"></img>"+
"</body>\n"+
"</html>";
mailService.sendInLinResourceMail(to, subject, content,filePath,rscId);
}6. 和thymeleaf整合模板郵件
新增thymeleaf支援
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>templates資料夾下面新建 emailTemplate.html檔案
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>郵件模板</title>
</head>
<body>
這是一份註冊郵箱感謝支援，，。。。。。。。測試。。。。 點選下面的連結
<a href="#" th:href="@{http://www.baidu.com/{id}(id=${id})}">啟用賬號 </a>
</body>
</html>test方法
@Resource
TemplateEngine templateEngine;
//模板郵件
@Test
public void testTmeplateMail() throws Exception {
Context context = new Context();
context.setVariable("id", "008");
String emailContent=templateEngine.process("emailTemplate", context);
String to="[email protected]";
String subject="模板中的郵件";
mailService.sendHtmlMain(to, subject, emailContent);;
}關於異常捕獲：
private final Logger logger=(Logger) LoggerFactory.getLogger(this.getClass());
public void sendInLinResourceMail(String to,String subject,String content,String rscPath,String rscId) {
logger.info("開始傳送郵件。。。。{},{},{},{},{}",to,subject,content,rscPath,rscId);
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper;
try {
helper = new MimeMessageHelper(message,true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content,true);
helper.setFrom(from);
FileSystemResource fileSystemResource = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, fileSystemResource);
mailSender.send(message);
logger.info("傳送郵件成功。。。。。。。。。");
} catch (MessagingException e) {
logger.error("傳送郵件失敗。。。。。。。。。");
}
}郵件傳送到此結束
以後可以考慮 做微服務，或者放佇列
