本篇内容主要讲解“怎么用SpringBoot实现QQ邮箱发送邮件”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“怎么用SpringBoot实现QQ邮箱发送邮件”吧!
1.获取QQ邮箱授权码
2.导入邮箱发送依赖启动器
使用定制邮件模板的方法实现通用邮件发送，Thymeleaf构建邮件模板需要一起导入依赖。
<!-- Mail --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency> <!-- thymeleaf模板依赖 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>3.配置文件yml添加邮件服务配置
# Spring配置spring: mail: host: smtp.qq.com username: ********@qq.com # password是第一步QQ邮箱开通的smtp服务后得到的客户端授权码 password: ****************** default-encoding: UTF-8 properties: mail: smtp: auth: true starttls: enable: true required: true#thymeleaf模板引擎配置太简单，就不贴出来了4.编写接口IMailService
public interface IMailService { void sendHtmlMailThymeLeaf(String mailFrom, String mailFromNick, String mailTo, String cc, String subject, String content);}5.编写实现MailServiceImpl
@Servicepublic class MailServiceImpl implements IMailService { @Autowired private JavaMailSender mailSender; @Override public void sendHtmlMailThymeLeaf(String mailFrom, String mailFromNick, String mailTo, String cc, String subject, String content) { MimeMessage mimeMessage = mailSender.createMimeMessage(); try { MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true); mimeMessageHelper.setFrom(new InternetAddress(mailFromNick + " <" + mailFrom + ">")); // 设置多个收件人 String[] toAddress = mailTo.split(","); mimeMessageHelper.setTo(toAddress); if (!StringUtils.isEmpty(cc)) { mimeMessageHelper.setCc(cc); } mimeMessageHelper.setSubject(subject); // 第二个参数为true表示邮件正文是html格式的，默认是false mimeMessageHelper.setText(content, true); mailSender.send(mimeMessage); } catch (MessagingException e) { System.out.println(e); } }}6.Controller调用
// 发件人要跟yml配置文件里填写的邮箱一致 String mailFrom = "******@qq.com"; // 收件人 String mailTo = "******@qq.com,******@qq.com"; // 抄送(可为空) String cc = "******@qq.com"; // 注入mailService @Autowired private IMailService mailService; // 注入TemplateEngine @Autowired TemplateEngine templateEngine; @RequestMapping("/other/test")//请求路径 @ResponseBody public void testMail() { //注意1：这里我是查询对应的内容,使用富文本编辑器存储html标签的内容 Strategy strategy = strategyService.selectStrategyByStrategyId(Long.valueOf(1)); Context context = new Context(); // 导包是org.thymeleaf.context //注意2：获取发送的内容传入thymeleaf模板中 context.setVariable("content", strategy.getStrategyContent()); String content = templateEngine.process("mailTemplate.html", context); //System.out.println(content); mailService.sendHtmlMailThymeLeaf(mailFrom, "定义发件人名字", mailTo, cc, "定义邮件标题", content); System.out.println("邮件发送成功"); }7.thymeleaf模板 mailTemplate.html
<!DOCTYPE html><html lang="en" xmlns:th="http://www.thymeleaf.org"><head> <meta charset="UTF-8"> <title>邮件发送</title></head><body> <!--使用富文本框包含HTML标签 使用 th:utext标签 会解析html，显示相应的效果--><div th:utext="${content}">Some escaped text</div></body></html>到此，相信大家对“怎么用SpringBoot实现QQ邮箱发送邮件”有了更深的了解，不妨来实际操作一番吧！这里是编程网网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
