SpringBoot-19-之发送邮件
零、准备工作
<!--发送邮件的依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>spring:
mail:
host: smtp.126.com
username: toly1994@126.com
password: 你的密码--注意不是登陆密码，见下图：
default-encoding: utf-8点设置，会有让设置pop3密码的地方

一、发送简单邮件
toly1994.com.toly_email.service.MailService
@Service
public class MailService {
@Value("${spring.mail.username}")
private String from;
@Autowired
private JavaMailSender mJavaMailSender;
public void sendSimpleMail(String to, String subject, String content) {
SimpleMailMessage msg = new SimpleMailMessage();
msg.setTo(to);
msg.setSubject(subject);
msg.setText(content);
msg.setFrom(from);
mJavaMailSender.send(msg);
}
}toly1994.com.toly_email.controller.MailController
@RestController
public class MailController {
@Autowired
private MailService mMailService;
@GetMapping("/send")
public String send() {
mMailService.sendSimpleMail("1981462002@qq.com","你好","张风捷特烈");
return "send";
}
}

二、发送Html邮件
toly1994.com.toly_email.service.MailService
public void sendHtmlMail(String to, String subject, String content) throws MessagingException {
MimeMessage msg = mJavaMailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(msg, true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
helper.setFrom(from);
mJavaMailSender.send(msg);
}toly1994.com.toly_email.controller.MailController
@GetMapping("/sendHtml")
public String sendHtml() {
String html =
"<html\n" +
"<body>\n" +
"<h3> Hello Toly</h3>\n" +
"</body>\n" +
"</html>";
try {
mMailService.sendHtmlMail("1981462002@qq.com", "你好", html);
} catch (MessagingException e) {
e.printStackTrace();
}
return "send";
}

三、发送附件
推荐压缩一下成zip再发送。
toly1994.com.toly_email.service.MailService
/**
*
* @param to 收信人
* @param subject 主题
* @param content 内容
* @param paths 路径
* @throws MessagingException
*/
public void sendSubFileMail(String to, String subject, String content, String... paths) throws MessagingException {
MimeMessage msg = mJavaMailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(msg, true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
helper.setFrom(from);
for (String path : paths) {
FileSystemResource fsr = new FileSystemResource(new File(path));
String filename = fsr.getFilename();
System.out.println(filename);
helper.addAttachment(filename, fsr);
}
mJavaMailSender.send(msg);
}toly1994.com.toly_email.controller.MailController
@GetMapping("/sendSubFile")
public String sendSubFile() {
String path = "F:\\SpringBootFiles\\file\\springboot.zip";
String path2 = "F:\\SpringBootFiles\\file\\MySQL.zip";
try {
mMailService.sendSubFileMail("1981462002@qq.com","你好","张风捷特烈",path,path2);
} catch (MessagingException e) {
e.printStackTrace();
}
return "send";
}

四、发送图片
toly1994.com.toly_email.service.MailService
/**
* 发送带图片的邮件
* @param to
* @param subject
* @param content
* @param resPath
* @param resId
* @throws MessagingException
*/
public void sendImgMail(String to, String subject, String content,
String resPath,String resId) throws MessagingException {
MimeMessage msg = mJavaMailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(msg, true);
helper.setTo(to);
helper.setSubject(subject);
helper.setText(content, true);
helper.setFrom(from);
FileSystemResource fsr = new FileSystemResource(new File(resPath));
helper.addInline(resId, fsr);
mJavaMailSender.send(msg);
}toly1994.com.toly_email.controller.MailController
@GetMapping("/sendImgMail")
public String sendImgMail() {
String imgPath = "E:\\Photo\\picpic\\Android\\timg.jpg";
String resId = "001";
String content =
"<html><body> 图片邮件：<img width='300' src=\'cid:"+resId+"\'></img></body></html>";
try {
mMailService.sendImgMail("1981462002@qq.com","发一张图片给你",content,imgPath,resId);
} catch (MessagingException e) {
e.printStackTrace();
}
return "send";
}

五、发送模板邮件：使用thymeleaf，不熟悉的小伙伴可移驾到这篇：模板引擎--thymeleaf
toly1994.com.toly_email.controller.MailController
@Autowired
private TemplateEngine mTemplateEngine;
@GetMapping("/sendTempMail")
public String sendTempMail() {
Context context = new Context();
context.setVariable("id", "99531e7006e0");
String emailTemp = mTemplateEngine.process("emailTemp", context);
try {
mMailService.sendHtmlMail("1981462002@qq.com","模板邮件",emailTemp);
} catch (MessagingException e) {
e.printStackTrace();
}
return "OK";
}模板：templates/emailTemp.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
