springboot发送邮件

1. 依赖

java 复制代码

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

2. 在application.yml文件中配置JavaMail

java 复制代码

spring:
   mail:
    # 邮箱服务器
    host: smtp.qq.com
    # 邮箱
    username: [email protected]
    # 授权码,不是登录密码
    password: xxxxxxxx

授权码获取

各种邮箱获取授权码

3. 无附件,简单内容发送

java 复制代码

import com.itheima.service.SendMailService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;
 
@Service
public class SendMailServiceImpl implements SendMailService {
    @Autowired
    private JavaMailSender javaMailSender;
    //发送人
    private String from = "[email protected]";
    //接收人
    private String to = "[email protected]";
    //标题
    private String subject = "测试邮件";
    //正文
    private String context = "测试邮件正文内容";
    @Override
    public void sendMail() {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from+"(小甜甜)");
        message.setTo(to);
        message.setSubject(subject);
        message.setText(context);
        javaMailSender.send(message);
    }
}

import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;

            File f2 = new File("E:\\guigu\\test\\src\\mail\\word1.docx");
 
            helper.addAttachment(f1.getName(),f1);
            helper.addAttachment("最靠谱的培训结构.png",f2);
 
            javaMailSender.send(message);
        } catch (Exception e) {
