这篇文章将为大家详细讲解有关SpringBoot集成E-mail发送各种类型邮件的方法，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
JDK本身有自带发送邮件api，加上SpringBoot在进行封装，使得现在使用起来十分快速简洁。
话不多说，参考纯洁的微笑博客，更改jar版本为2.0.4 开干，基本没什么坑。
就是配置邮箱账号密码是，如果是qq邮箱，需要开启PO30和STMP服务，并且获取临时授权码。
开启服务链接：
https://mail.qq.com/cgi-bin/frame_html?sid=a5ZSbreeNm9pHyl1&r=a83225170e94773c650a460c10f7a05c
与Springboot集成
导入jar包
compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.0.4.RELEASE' compile 'org.springframework.boot:spring-boot-starter-thymeleaf:2.0.4.RELEASE'
配置邮箱
#邮箱服务器地址，各大运营商不同 spring.mail.host=smtp.qq.com #用户名 spring.mail.username=9118542413@qq.com #密码，如果是qq的，要申请临时授权码 spring.mail.password=faw124awfawfawg spring.mail.default-encoding=UTF-8 #以谁来发送邮件 mail.fromMail.addr=9118542413@qq.com
发送各种类型的邮件

FileSystemResource file = new FileSystemResource(new File(filePath));
String fileName = filePath.substring(filePath.lastIndexOf(File.separator) + 1);
helper.addAttachment(fileName, file);
mailSender.send(message);
log.info("带附件的邮件已经发送。");
} catch (MessagingException e) {
log.error("发送带附件的邮件时发生异常！", e);
}
}
@Override
public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId) {

}
}
@Override
public void sendTemplateMail(String to, String subject, String template, Context context) {
String emailContent = templateEngine.process(template, context);
sendHtmlMail("15017263512@163.com", "主题：这是模板邮件", emailContent);
}
}测试类：
@RunWith(SpringRunner.class)
@SpringBootTest
public class EmailServiceTest {
@Autowired
MailService mailService;
@Test
public void sendSimpleMailTest() {
mailService.sendSimpleMail("15017263512@163.com","test simple mail"," hello this is simple mail");
}
@Test
public void sendHtmlMailTest(){
String content="<html>\n" +
"<body>\n" +
" <h4>hello world ! 这是一封Html邮件!</h4>\n" +
"</body>\n" +
"</html>";
mailService.sendHtmlMail("15017263512@163.com","test html mail",content);
}
@Test
public void sendAttachmentsMail(){
String filePath="E:\\var\\log\\elkTest\\error\\2018-11-30.log";
mailService.sendAttachmentsMail("15017263512@163.com", "主题：带附件的邮件", "有附件，请查收！", filePath);
}
@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\\Admin\\Pictures\\Camera Roll\\9499189867_1476052069.jpg";
mailService.sendInlineResourceMail("15017263512@163.com", "主题：这是有图片的邮件", content, imgPath, rscId);
}
@Test
public void sendTemplateMail() {
//创建邮件正文
Context context = new Context();
context.setVariable("id", "006");
mailService.sendTemplateMail("15017263512@163.com","主题：这是模板邮件",
"emailTemplate",context);
}
