springboot 发送QQ邮件

1.开启发送端邮箱的smtp服务，登录进入后设置

2.引入依赖包

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

3.添加设置信息 

#配置邮件消息
spring.mail.host=smtp.qq.com
#发送邮件者信箱
spring.mail.username=******@qq.com
#这里不是邮箱的登录密码，而是开启PO3/SMTP服务时邮箱的授权码
spring.mail.password= ******
spring.mail.default-encoding=UTF-8
spring.mail.port=587
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.debug=true

4.添加邮件工具类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.mail.internet.MimeMessage;
@Component
public class MailUtil {
    @Autowired
    private JavaMailSender jms;

    public void sendMail(String toUser, String subject, String text){
        try {
            MimeMessage mimeMessage = jms.createMimeMessage();
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
            // 设置发信人，发信人需要和spring.mail.username配置的一样否则报错
            message.setFrom("[email protected]");
            // 设置收信人
            message.setTo(toUser);
            // 设置主题
            message.setSubject(subject);
            // 第二个参数true表示使用HTML语言来编写邮件
            message.setText(text,true);
/*FileSystemResource file = new FileSystemResource(
new File("src/main/resources/static/image/picture.jpg"));
helper.addAttachment("图片.jpg", file);//添加带附件的邮件
helper.addInline("picture",file);//添加带静态资源的邮件*/
            jms.send(mimeMessage);

        } catch (Exception ex) {
            ex.printStackTrace();

        }
    }
}

5.发送时调用工具类

mailUtil.sendMail(接收方, 标题, 内容);
