SpringBoot整合邮件任务（QQ邮箱发送）
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>
# 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
public interface IMailService {
void sendHtmlMailThymeLeaf(String mailFrom, String mailFromNick, String mailTo, String cc, String subject, String content);
}
@Service
public class MailServiceImpl implements IMailService {
/**
* JavaMailSender是Spring Boot在MailSenderPropertiesConfiguration 类中配直好的，该类在 Mail
* 自动配置类 MailSenderAutoConfiguration 中导入 因此这里注入 JavaMailSender 就可以使用了
*/
@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);
}
}
}
// 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");
