SpringBoot整合邮件任务（QQ邮箱发送）

SpringBoot整合邮件任务（QQ邮箱发送） SpringBoot整合邮件任务（QQ邮箱发送） 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。

       
        
            org.springframework.boot
            spring-boot-starter-mail
        

        
        
            org.springframework.boot
            spring-boot-starter-thymeleaf
        

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

@Service
public 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
