SpringBoot 邮件任务
SpringBoot 邮件任务
今天学习了异步任务和邮件任务等等，写篇随笔记录一下邮件任务
导入依赖(也可以自己创建SpringBoot项目时勾选上启动器)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
开启POP3/SMTP服务(这里以QQ邮箱为例)
登录QQ邮箱，在设置->帐户寻找下面的服务
编写配置文件(这里使用properties)
# 填写自己的邮箱 这里以QQ邮箱为例
spring.mail.username=*********@qq.com
# 这里是自己邮箱的授权码，如果是QQ邮箱，需要自己去开启服务，并且获取授权码，其它邮箱就是自己的密码
spring.mail.password=*************
spring.mail.host=smtp.qq.com
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
# 开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=true
测试
@Autowired
JavaMailSender javaMailSender;
@Test
void contextLoads() {
//发送简单邮件
SimpleMailMessage message = new SimpleMailMessage();
message.setSubject("激活邮件"); //设置标题
message.setText("您好,这是一封测试邮件,无需回复"); //设置正文
message.setTo("2933253458@qq.com"); //发给谁
message.setFrom("2933253458@qq.com"); //谁发的
javaMailSender.send(message);
}
@Autowired
JavaMailSender javaMailSender;
@Test
public void test01() throws MessagingException {
//发送复杂邮件(html+附件)
MimeMessage mimeMessage = javaMailSender.createMimeMessage();
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage,true);
mimeMessageHelper.setSubject("激活邮件"); //设置邮件主题
mimeMessageHelper.setText("<p>您好,这是一封测试邮件！<p>",true);//开启解析html
//发送附件
mimeMessageHelper.addAttachment("图片.png",new File("C:\\Users\\gaoteng\\Desktop\\Typora截图\\QQ截图20200613091605.png"));
//发给谁
mimeMessageHelper.setTo("2933253458@qq.com");
//谁发的
mimeMessageHelper.setFrom("2933253458@qq.com");
javaMailSender.send(mimeMessage);
}
抽取工具类(这是在网上找的某大佬的，后面会附上链接)

//第二个参数指定发送的是HTML格式,同时cid:是固定的写法
//"<html><body>带静态资源的邮件内容 图片:<img src='cid:picture' /></body></html>"
helper.setText(html, true);
Set<Map.Entry<String,File>> fileSet = files.entrySet();

}
因为测试结果太多，所以我就不贴图片了.
本篇随笔参考使用spring-boot-starter-mail实现邮件发送。
特别感谢!!!
