2、在 application.properties 中添加邮箱配置spring.mail.host=smtp.qiye.163.com //邮箱服务器地址 spring.mail.username=xxx@oo.com //用户名 spring.mail.password=xxyyooo //密码 spring.mail.default-encoding=UTF-8 mail.fromMail.addr=xxx@oo.com //以谁来发送邮件3、编写 mailService,这里只提出实现类。
@Component
public class MailServiceImpl implements MailService{
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private JavaMailSender mailSender;
@Value("${mail.fromMail.addr}")
private String from;
@Override
public void sendSimpleMail(String to, String subject, String content) {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo(to);
message.setSubject(subject);
message.setText(content);
try {
mailSender.send(message);
logger.info("简单邮件已经发送。");
} catch (Exception e) {
logger.error("发送简单邮件时发生异常!", e);
}
}
}
4、编写 test 类进行测试@RunWith(SpringRunner.class)
@SpringBootTest
public class MailServiceTest {
@Autowired
private MailService MailService;
@Test
public void testSimpleMail() throws Exception {
MailService.sendSimpleMail("test@126.com","test simple mail"," hello this is simple mail");
}
}
至此一个简单的文本发送就完成了。public void sendHtmlMail(String to, String subject, String content) {
MimeMessage message = mailSender.createMimeMessage();
try {
//true表示需要创建一个multipart message
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
// 堆代码 duidaima.com
mailSender.send(message);
logger.info("html邮件发送成功");
} catch (MessagingException e) {
logger.error("发送html邮件时发生异常!", e);
}
}
在测试类中构建 html 内容,测试发送@Test
public void testHtmlMail() throws Exception {
String content="<html>\n" +
"<body>\n" +
" <h3>hello world ! 这是一封Html邮件!</h3>\n" +
"</body>\n" +
"</html>";
MailService.sendHtmlMail("test@126.com","test simple mail",content);
}
发送带附件的邮件public void sendAttachmentsMail(String to, String subject, String content, String filePath){
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
helper.addAttachment(fileName, file);
mailSender.send(message);
logger.info("带附件的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送带附件的邮件时发生异常!", e);
}
}
添加多个附件可以使用多条 helper.addAttachment(fileName,file)@Test
public void sendAttachmentsMail() {
String filePath="e:\\tmp\\application.log";
mailService.sendAttachmentsMail("test@126.com", "主题:带附件的邮件", "有附件,请查收!", filePath);
}
发送带静态资源的邮件public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){
MimeMessage message = mailSender.createMimeMessage();
try {
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(from);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
FileSystemResource res = new FileSystemResource(new File(rscPath));
helper.addInline(rscId, res);
mailSender.send(message);
logger.info("嵌入静态资源的邮件已经发送。");
} catch (MessagingException e) {
logger.error("发送嵌入静态资源的邮件时发生异常!", e);
}
}
在测试类中添加测试方法@Test
public void sendInlineResourceMail() {
String rscId = "neo006";
String content="<html><body>这是有图片的邮件:<img src=\'cid:" + rscId + "\' ></body></html>";
String imgPath = "C:\\Users\\summer\\Pictures\\favicon.png";
mailService.sendInlineResourceMail("test@126.com", "主题:这是有图片的邮件", content, imgPath, rscId);
}
添加多个图片可以使用多条 <imgsrc='cid:" + rscId + "'> 和 helper.addInline(rscId,res) 来实现。到此所有的邮件发送服务已经完成了。<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
2、在 resorces/templates 下创建 emailTemplate.html<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
</head>
<body>
您好,这是验证邮件,请点击下面的链接完成验证,<br/>
<a href="#" th:href="@{ http://www.test.com/{id}(id=${id}) }">激活账号</a>
</body>
</html>
3、解析模板并发送@Test
public void sendTemplateMail() {
//创建邮件正文
Context context = new Context();
context.setVariable("id", "006");
String emailContent = templateEngine.process("emailTemplate", context);
mailService.sendHtmlMail("test@126.com","主题:这是模板邮件",emailContent);
}
发送失败3、启动定时系统扫描时间段内,未发送成功并且重试次数小于3次的邮件,进行再次发送
